On Earth, we can find water in the seas, lakes, oceans, streams, rivers etc. Water also comes in form of rain as well.
In a hotel breakfast bar, you see an older woman sticking a fork into a toaster to remove a piece of toast. You warn her not to do that, and she says, "You know, I always wondered why forks conduct electricity so well." As an astute chemistry student, how would you explain it to her? Make sure you provide a relationship to electronegativity, proton pull, and electron distribution in your answer.
Answer:
See explanation
Explanation:
You see, all these materials we see around us are composed of elements. These elements are unique in their own ways!
Some of them are able to attract tiny negative particles called electrons close to their positive interior called the nucleus. This positive interior is so designated because it contains a positive particle called protons which attract these electrons.
Now, elements are broadly divided into metals and non metals. Protons in metallic elements are less able to pull electrons than protons in non metallic elements. As a result of this, non metals are mostly electronegative because they pull electrons towards themselves while metals are mostly electropositive because they give away their electrons easily. Fork is composed of metallic elements.
Since metals give away electrons easily, they can conduct electricity since electrons are the same charge carriers in electric circuits.
Also, in elements, there is a conduction band and a valence band. Electrons occupy the valence band but also move into the conduction band. The gap between the valence band and the conduction band in nonmetals is large hence they do not conduct electricity. The gap between the valence band and the conduction band in metals is minimal hence metals conduct electricity.
So if you stick that fork into a toaster, electrons can flow right through the toaster circuit into your body and cause you to be electrocuted.

A solid piece of lead has a mass of 32.00 g and a volume of 2.84 cm^3. From these data, calculate the density of lead in SI units (kilograms per cubic meter).
Answer:
11267.61 Kg/m³.
Explanation:
From the question given above, the following data were obtained:
Mass of lead = 32 g
Volume of lead = 2.84 cm³
Density of lead =.?
Next, we shall convert 32 g to Kg. This can be obtained as follow:
1000 g = 1 Kg
Therefore,
32 g = 32 g × 1 Kg / 1000 g
32 g = 0.032 Kg
Next, we shall convert 2.84 cm³ to m³. This can be obtained as follow:
1 cm³ = 10¯⁶ m³
Therefore,
2.84 cm³ = 2.84 cm³ × 10¯⁶ m³ / 1 cm³
2.84 cm³ = 2.84×10¯⁶ m³
Finally, we shall determine the density of the piece of lead. This can be obtained as follow:
Mass of lead = 0.032 Kg
Volume of lead = 2.84×10¯⁶ m³
Density of lead =.?
Density = mass / volume
Density of lead = 0.032 / 2.84×10¯⁶
Density of lead = 11267.61 Kg/m³

When of a certain molecular compound X are dissolved in of benzene , the freezing point of the solution is measured to be . Calculate the molar mass of X. If you need any additional information on benzene, use only what you find in the ALEKS Data resource. Also, be sure your answer has a unit symbol, and is rounded to the correct number of significant digits.
The question is incomplete. Here is the complete question.
When 2.10 g of a certain molecular compound X are dissolved in 65.0 g of benzene (C₆H₆), the freezing point of the solution is measured to be 3.5°C. Calculate the molar mass of X. If you need any additional information on benzene, use only what you find in the ALEKS Data resource. Also, be sure your answer has a unit symbol, and is rounded to 2 significant digits.
Answer: MM = 47.30 g/mol.
Explanation: There is a relationship between freezing point depression and molality. With this last one, is possible to calculate molar mass or molar weight of a compound.
Freezing Point Depression occurs when a solute is added to a solvent: the freezing point of the solvent decreases when a non-volatile solute is incremented.
Molality or molal concentration is a quantity of solute dissolved in a certain mass, in kg, of solvent. Its symbol is m and it's defined as
[tex]m=\frac{moles(solute)}{kg(solvent)}[/tex]
Freezing point depression and molal are related as the following:
[tex]\Delta T_{f}=K_{f}.m[/tex]
where
[tex]\Delta T_{f}[/tex] is freezing point depression of solution
[tex]K_{f}[/tex] is molal freezing point depression constant
m is molality
Now, to determine molar mass, first, find molality of the mixture:
[tex]\Delta T_{f}=K_{f}.m[/tex]
[tex]m=\frac{\Delta T_{f}}{K_{f}}[/tex]
For benzene, constant is 5.12°C/molal. Then
[tex]m=\frac{3.5}{5.12}[/tex]
m = 0.683 molal
Second, knowing the relationship between molal and moles of solute, determine the last one:
[tex]m=\frac{moles(solute)}{kg(solvent)}[/tex]
[tex]mol(solute)=m.kg(solvent)[/tex]
mol(solute) = 0.683(0.065)
mol(solute) = 0.044 mol
The definition for Molar mass is the mass in grams of 1 mol of substance:
[tex]n(moles)=\frac{m(g)}{MM(g/mol)}[/tex]
[tex]MM=\frac{m}{n}[/tex]
In the mixture, there are 0.044 moles of X, so its molecular mass is
[tex]MM=\frac{2.1}{0.044}[/tex]
MM = 47.30 g/mol
The molecular compound X has molecular mass of 47.30 g/mol.
g Aqueous hydrobromic acid will react with solid sodium hydroxide to produce aqueous sodium bromide and liquid water . Suppose 57.4 g of hydrobromic acid is mixed with 41. g of sodium hydroxide. Calculate the minimum mass of hydrobromic acid that could be left over by the chemical reaction. Be sure your answer has the correct number of significant digits.
Answer:
Zero
Explanation:
The complete reaction for this is as follows -
HBr + NaOH = NaBr + H2O
1 mole of NaOH reacts with 1 mole of HBr
m(HBr) = 57.4g and M(HBr) = 80.9g/mol
m(NaOH) = 16g and M(NaOH) = 40g/mol
Number of moles = m/M
Substituting the given values we get -
n(HBr) = 57.4 g/80.9 g/mol = 0.709
n(NaOH) = 16 g/40 g/mol = 0.4
n(H2O) = n(NaOH) = 0.40 mol
According to balanced equation
40 gram of NaOH reacts with 81 grams of HBr
41 gram of NaOH will react with 81/40 * 41 = 83.025 gram of HBr
We have only 57.4 g of HBr only hence, 0 HBr will be left.

Mg(s)+2HCl(aq) → MgCl2(aq)+H2(g)
In an experiment, a student places a small piece of pure Mg(s) into a beaker containing 250.mL of 6.44MHCl(aq). A reaction occurs, as represented by the equation above. The student collects the H2(g) produced by the reaction and measures its volume over water at 298 K after carefully equalizing the water levels inside and outside the gas-collection tube. The volume is measured to be 45.6mL. The atmospheric pressure in the lab is measured as 765 torr, and the equilibrium vapor pressure of water at 298 K is 24 torr.
Calculate the following.
(i) The pressure inside the tube due to the H2(g)
(ii) The number of moles of H2(g) produced in the reaction
What is the answer and why?
Answer:
741 torr
0.81 moles of H2
Explanation:
Given the reaction equation;
Mg(s)+2HCl(aq) → MgCl2(aq)+H2(g)
We can obtain the pressure of the gas at 298 K using Dalton's law of partial pressures.
Pressure of gas + vapour pressure of water = 765 torr
vapour pressure of water = 24 torr
765 torr - vapour pressure of water = Pressure of gas
Pressure of gas = 765 torr - 24 torr = 741 torr

1.61 moles of HCl yields 1.61 * 1/2 = 0.81 moles of H2
In the United States, barometric pressures a re generally reported in inches of mercury (in. Hg). On a beautiful summer day in Chicago, the barometric pressure is 30.45 in. Hg. Convert this pressure to torr.
Answer:
773.43 torr
Explanation:
From the question given above, the following data were obtained:
Pressure (in inHg) = 30.45 inHg
Pressure (in torr) =?
We can convert 30.45 inHg to torr by doing the following:
1 inHg = 25.4 torr
Therefore,
30.45 inHg = 30.45 inHg × 25.4 torr / 1 inHg
30.45 inhg = 773.43 torr
Thus, 30.45 inhg is equivalent to 773.43 torr

(a) Find the increase in internal energy if only translational and rotational motions are possible. (b) Find the increase in internal energy if translational, rotational, and vibrational motions are possible. (c) How much of the energy calculated in (a) and (b) is translational kinetic energy?
Answer:
a) the increase in internal energy is 3211.78 J
b) dU = 3854.14 J
c) dU[tex]_{T}[/tex] = 1927.06 J
Explanation:
Given the data in question;
Foe a diatomic gas, the degree of freedom are as follow;
lets consider the positional degree of freedom
transitional df = 3
rotational df = 2
vibrational ff = 1
now, the internal energy given by;
U = Nf × 1/2NKT = Nf×1/2×nRT
where Nf is the number of degree of freedom
N is Number of atoms or molecules
n = number of molecules
L is Boltzmann constant
R is universal gas constant
so change in internal energy , change in T is given by
dU = Nf × 1/2 × nT dT
n = 2.37 moles
dT = 65.2 K
R = 8.314 J/mol.J
a)
Find the increase in internal energy if only translational and rotational motions are possible
since rotational and transitional motion are involved ;
Nf = 3(trasitional) + 2(rotational) = 5
so,
dU = 5 × 1/2 × nRdT
we substitute
dU = 5 × 0.5 × 2.37 × 8.314 × 65.2
dU = 3211.78 J
Therefore, the increase in internal energy is 3211.78 J
b)
Find the increase in internal energy if translational, rotational, and vibrational motions are possible.
Nf = 3 + 2 + 1 = 6
dU = 6 × 1/2 × nRdT
dU = 6 × 0.5 × 2.37 × 8.314× 65.2
dU = 3854.14 J
c)
How much of the energy calculated in (a) and (b) is translational kinetic energy?
dU[tex]_{T}[/tex] = 3 × 0.5 × 2.37 × 8.314 × 65.2
dU[tex]_{T}[/tex] = 1927.06 J

An unknown compound is processed using elemental analysis and found to contain 117.4 g of platinum, 28.91 g of carbon, and 33.71 g of nitrogen. How many moles of platinum are present in the compound? Need help ASAP
Answer:
1 mole of platinum (Pt).
Explanation:
From the question given above, the following data were obtained:
Platinum (Pt) = 117.4 g
Carbon (C) = 28.91 g
Nitrogen (N) = 33.71 g
Number of mole of platinum =?
To obtain the number of mole of platinum present in the compound, we shall determine the empirical formula for the compound. The empirical formula for the compound can be obtained as follow:
Pt = 117.4 g
C = 28.91 g
N = 33.71 g
Divide by their molar mass
Pt = 117.4 /195 = 0.602
C = 28.91 /12 = 2.409
N = 33.71 /14 = 2.408
Divide by the smallest
Pt = 0.602 /0.602 = 1
C = 2.409 /0.602 = 4
N = 2.408 / 0.602 = 4
Therefore, the empirical formula for the compound is PtC₄N₄ => Pt(CN)₄
From the empirical formula for the compound (i.e Pt(CN)₄) we can see that the compound contains 1 mole of platinum (Pt).

The following experimental data are obtained for the amount of A as the reaction proceeds. What is the average rate of appearance of B in units of M/s between t = 10.0 min. and t = 30.0 min.? Assume that the volume of the flask is constant.

A 100.0 mL flask is filled with 0.065 moles of A and allowed to react to form B according to the reaction below. The following experimental data are obtained for the amount of A as the reaction proceeds. What is the average rate of appearance of B in units of M/s between t = 10 min. and t = 30 min.? Assume that the volume of the flask is constant. A(g) → B(g)
Time 0.0 10.0 20.0 30.0 40.0
Moles of A 0.065 0.051 0.042 0.036 0.031
Solution :
Consider the following reaction as follows :
[tex]$A \rightarrow B$[/tex]
The experiment data is given as follows :
Time (min) : 0.0 10.0 20.0 30.0 40.0
Moles of A : 0.065 0.051 0.042 0.036 0.031
According to the rate of reaction concept, the rate can be expressed as a consumption of the reactant and formation of the product as follows :
Average rate : [tex]$= -\frac{d[A]}{dt} = \frac{d[B]}{dt} $[/tex]
Now we have to calculate the average rate between 10.0 to 30.0 min w.r.t. A as follows :
Rate [tex]$=-\frac{(0.051-0.036) mol \times \frac{1}{0.1 \ L}}{(30.0-10.0) mol \times \frac{60 \ s}{1 \ min}}$[/tex]
[tex]$=\frac{0.15 \ M}{20 \ min \times \frac{60 \ s}{1 \ min}}$[/tex]
[tex]$= 1.25 \times 10^{-4 }\ M/s$[/tex]
Therefore, the rate = [tex]$= 1.3 \times 10^{-4 }\ M/s$[/tex]
A 100.0-mL flask is filled with 0.065 moles of A and allowed to react to form B. Between 10.0 min and 30.0 min, the average rate of appearance of B is 1.3 × 10⁻⁴ M/s.
What is the rate of reaction?The rate of reaction is the speed at which a chemical reaction takes place, defined as proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time.
Step 1: Write the balanced equation.A(g) → B(g)
Step 2: Calculate the rate of reaction of A (rate of disappearance of A).To calculate the rate of disappearance of A (rA) between 10.0 min and 30.0 min, we will use the following expression.
rA = -ΔnA / V. Δt = -(0.036 mol - 0.051 mol)/ (0.1000 L) (30.0 min - 10.0 min)
rA = 7.5 × 10⁻³ M/min
where,
ΔnA is the change in the number of moles of A.Δt is the change in time.Step 3: Calculate the rate of reaction of B (rate of appearance of B).The molar ratio of A to B is 1:1.
7.5 × 10⁻³ mol A/L.min × 1 mol B/1 mol A = 7.5 × 10⁻³ mol B/L.min
Step 4: Convert 7.5 × 10⁻³ M/min to M/sWe will use the conversion factor 1 min = 60 s.
7.5 × 10⁻³ M/min × 1 min/60 s = 1.3 × 10⁻⁴ M/s
A 100.0-mL flask is filled with 0.065 moles of A and allowed to react to form B. Between 10.0 min and 30.0 min, the average rate of appearance of B is 1.3 × 10⁻⁴ M/s.
