Part 1Observe The Image Of Sodium. List The Properties You See.Part 2Observe The Image Of Hydrogen Chloride.

Answers

Answer 1

Answer:

Observable properties of sodium from the image:

1. It's slivery-white solid

2. It's shiny and bright

3. Looks soft

4. Looks waxy

Observable properties of hydrogen chloride from the image:

1. It is a colorless liquid

2. It is transparent

Explanation:

Sodium is known to be a metal that is silvery-white and waxy in appearance. The metal is bright and shiny especially when it is cut. It can be cut with a knife due to it soft nature. It is reactive and has low melting point. It actually reacts with water to form sodium hydroxide.

Hydrogen chloride (known to be hydrochloric acid) is a transparent and colorless substance. It is used in manufacturing plastics, textile,  fertilizers, etc. The concentrated hydrogen chloride is very corrosive.

The above are what I can see from the image.

What is the chemical law?

Answers

Answer:

Chemical laws are those laws of nature relevant to chemistry. The most fundamental concept in chemistry is the law of conservation of mass, which states that there is no detectable change in the quantity of matter during an ordinary chemical reaction. Modern physics shows that it is actually energy that is conserved, and that energy and mass are related; a concept which becomes important in nuclear chemistry. Conservation of energy leads to the important concepts of equilibrium, thermodynamics, and kinetics.

Calculate the percentage composition of Aluminum, Sulfur & Oxygen in the compound of Al(SO4)3

Answers

Answer:

Percentage of O = 56.1 %

Percentage of Al =15.8%

Percentage of S = 28.1 %

Explanation:

Given compound Al₂(SO₄)₃

Molar mass of compound:

27×2 + 32×3 + 16×12 = 342 g/mol

Percentage of Al = ( Mass of Al / Total mass ) × 100

Percentage of Al = 54 /342 × 100

Percentage of Al =15.8%

Percentage of S = ( Mass of S / Total mass ) × 100

Percentage of S = 96 /342 × 100

Percentage of S = 28.1 %

Percentage of O = ( Mass of O / Total mass ) × 100

Percentage of O = 192 /342 × 100

Percentage of O = 56.1 %

4. When the mole fraction of solute is 1, there is
(a) a 1:1 ratio of solute to solvent.
(b) no solute present.
(c) only solute present.
(d) only solvent present.
(e) 1 mole of solute and 99 moles of solvent.

Answers

Answer:

(c) only solute present

Explanation:

In chemistry, the mole fraction, denoted by X, refers to the number of moles of a substance in a compound/mixture divided by the total number of substances in the same compound or mixture.

In this case, we can say that mole fraction represents the number of solutes to the number of solutes and solvent in the solution i.e. X = nA/nA + nB

Where; nA = number of solutes

nB = number of solvent

X = mole fraction.

Based on this analogy, When the mole fraction of solute is 1, there is only solute present. That is; X = 1 / 1 + 0

X = 1/1 = 1.

Use the mole concept to calculate the number of formula units that are in a 1.75-mol sample of NaCl.

Answers

Answer: There are [tex]10.5\times 10^{23}[/tex] formula units in 1.75 mol sample of NaCl.

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

1 mole of NaCl contains = [tex]6.023\times 10^{23}[/tex] formula units

Thus 1.75 mol of NaCl contains = [tex]\frac{6.023\times 10^{23}}{1}\times 1.75=10.5\times 10^{23}[/tex] formula units

Thus there are [tex]10.5\times 10^{23}[/tex] formula units in 1.75 mol sample of NaCl.

what is a unique characteristic of covalent bonding between nonmetal atoms
a) atoms give away electrons to reach a stable octet
b)atoms share valence electrons with neighboring atoms to reach a stable octect.
c)atoms gain electrons to reach a stable octet
d)delocalized electrons move freely among many positive atoms creating a ''sea'' of electrons

Answers

Answer:

The answer isssssssssssssss DRUM ROLL PLEASEEE

Explanation:

B

Considering the definition of covalent bonds,  the correct answer is option b): atoms share valence electrons with neighboring atoms to reach a stable octect.

Covalent bonds are the forces that hold non-metallic atoms together. These atoms have many electrons at their outermost level (valence electrons) and have a tendency to gain electrons rather than give them up, to acquire the stability of the noble gas electronic structure. Therefore, non-metallic atoms cannot give electrons to each other to form ions.

In other words, a covalent bond is a force that joins two atoms of non-metallic elements to form a molecule. Atoms share pairs of electrons from their most superficial shell (called the valence shell) to achieve the stability of the molecule that has been formed with the bond and thus comply with the octet rule.

In summary, the correct answer is option b): atoms share valence electrons with neighboring atoms to reach a stable octect.

If the [H+] of a solution is 6.8 x 10-9 mol/L the pH is

Answers

Answer:

8.2

Explanation:

To solve this problem;

 The concentration of [H⁺]   = 6.8 x 10⁻⁹mol/L

So, we need to convert this to pH:

           pH  = -log [H⁺]

So;

          pH  = -log 6.8 x 10⁻⁹ = 8.2

Thomas calculates the volume of an object by multiplying the measurements 1.74 cm x 2.3 cm x 3.09 cm. Using significant figures, how should the answer be reported?

Answers

Answer:

12 cm³

Explanation:

Always round to the place of the number with the least amount of significant figures.

1.74 and 3.09 have three significant figures. 2.3 has two significant figures. Therefore, the answer will be rounded to two significant figures.

1.74 cm × 2.3 cm × 3.09 cm = 12.36618 -> 12 cm³

(The 3 in the tenths place is less than 5 so drop it and all the numbers to the right of it.)

When chemists convert ethene (C2H2) to ethanol (CH3CH2OH), they have a mixture of the two gaseous substances. Why do chemists then lower the temperature of the mixture?

Answers

Answer:

to collect liquid ethanol and leave ethene as a gas because ethanol has hydrogen bonds    

Explanation:

The chemist would be lesser than the temperature of the mixture as to collect the liquid ethanol and then leave ethene as a gas since the ethanol is a bond that should be hydrogen. Also -OH that available in the ethanol would be responsible for the hydrogen bonds also it is the main and significant molecular forice

Answers

Answer:

0.01M = [H⁺]; 1x10⁻¹²M = [OH⁻]; Ratio is: 1x10¹⁰

Explanation:

pH is defined as -log [H⁺]

For a pH of 2 we can solve [H⁺] as follows:

pH = -log [H⁺]

2 = -log [H⁺]

10^-2 = [H⁺]

0.01M = [H⁺]

Using Keq of water:

Keq = 1x10⁻¹⁴ = [H⁺] [OH⁻]

1x10⁻¹⁴ / 0.01M = [OH⁻]

1x10⁻¹²M = [OH⁻]

The ratio is:

[H⁺] / [OH⁻] = 0.01 / 1x10⁻¹² =

A container with a volume of 893L contains how may moles of air at STP?

Answers

Answer:

i think 54

Explanation:

In the container with a volume of 893 liters, there are 39.9 moles of air at STP conditions.

We can find the number of moles with the Ideal gas law equation:

[tex] PV = nRT [/tex]

Where:

P: is the pressure = 1 atm (STP)

V: is the volume = 893 L

n: is the number of moles =?

R: is the gas constant = 0.082 L*atm/(K*mol)

T: is the temperature = 273 K

Hence, the number of moles is:

[tex] n = \frac{PV}{RT} = \frac{1 atm*893 L}{0.082 L*atm/(K*mol)*273 K} = 39.9 moles [/tex]

Therefore, there are 39.9 moles in the container.
