The weak acid HA is 4 % ionized (dissociated) in a 0.30 M solution. A. What is Ka for this acid?B. What is the pH of this solution?
Answer:
[tex]Ka=5x10^{-4}[/tex]
[tex]pH=1.92[/tex]
Explanation:
Hello,
In this case, given the percent ionization and the concentration of the acid, one computes the concentration of hydrogen ions as follows:
[tex]\% ionization=\frac{[H^+]}{[HA]}*100\%[/tex]
[tex][H^+]=\frac{\% ionization*[HA]}{100\%} =\frac{4\%*0.30M}{100\%}=0.012M[/tex]
Therefore the Ka is computed by using the equilibrium expression:
[tex]Ka=\frac{[H^+][A^-]}{[HA]} =\frac{0.012M*0.012M}{0.30M-0.012M}\\ \\Ka=5x10^{-4}[/tex]
And the pH:
[tex]pH=-log([H^+])=-log(0.012)\\\\pH=1.92[/tex]
Regards.
2.643 grams of potassium butanoate (KCH3(CH2)2CO2 ) is fully dissolved in 50.00 mL of water, which is carefully transferred to a conical flask. Then 100.00 mL of 0.120 M HCℓ is added dropwise to this solution from a burette. Given: Ka(butanoic acid) = 1.5 × 1O−5 . 2.1 Showing all your calculations and reasoning, determine the pH of the solution that results after the addition of all the acid mentioned above.
Answer:
The pH of the solution is 4.69
Explanation:
Given that,
Mass of potassium = 2.643 grams
Weight of water = 50.00 mL
Weight of HCl=100.00 ml
Mole = 0.120 M
We know that,
[tex]KCH_{3}(CH_{2})_{2}CO_{2}[/tex] is a basic salt.
Let's write it as KY.
The acid [tex]HCH_{3}(CH_{2}CO_{2})[/tex] would become HY.
We need to calculate the moles of KY
Using formula of moles
[tex]moles\ of\ KY=\dfrac{m}{M}\times1000[/tex]
[tex]moles\ of\ KY=\dfrac{2.643}{126}\times1000[/tex]
[tex]moles\ of\ KY=20.97\ m\ mole[/tex]
The reaction is
[tex]KY+HCl\Rightarrow HY+ KCl[/tex]
The number of moles of KY is 20.98 m
initial moles = 20.98
Final moles [tex]m=20.98-0.120\times100= 8.98[/tex]
We need to calculate the value of pKa(HY)
Using formula for pKa(HY)
[tex]pKa_{HY}=-log Ka[/tex]
[tex]pKa_{HY}=-log(1.5\times10^{-5})[/tex]
[tex]pKa_{HY}=4.82[/tex]
We need to calculate the pH of the solution
Using formula of pH
[tex]pH=pKa+log(\dfrac{[KY]}{[KH]})[/tex]
Put the value into the formula
[tex]pH=4.82+log(\dfrac{8.98}{12})[/tex]
[tex]pH=4,69[/tex]
Hence, The pH of the solution is 4.69

What types of compounds are CaCl2, Cu, C2H6, respectively.
Answer:
Ionic, metal, organic
Explanation:
In this case, we have to analyze each compound:
-) [tex]CaCl_2 [/tex]
In this compound, we have a non-metal atom (Cl) and a metal atom (Ca) . So, we will have a high electronegativity difference between these atoms, With this in mind, we will have an ionic bond. Ions can be produced:
[tex]CaCl_2~->~Ca^+^2~+~2Cl^-[/tex]
The cation would be [tex]Ca^+^2[/tex] and the anion is [tex]Cl^-[/tex]. So, we will have an ionic compound.
-) [tex]Cu[/tex]
In this case, we have a single atom. If we check the periodic table we will find this atom in the transition metals section (in the middle of the periodic table). So, this indicates that Cu (Copper) is a metal.
-) [tex]C_2H_6[/tex]
In this molecule, we have single bonds between carbon and hydrogen. The electronegativity difference between C and H are not high enough to produce ions. So, with this in mind, we will have covalent bonds. This is the main characteristic of organic compounds. (See figure 1)
CaCl₂, Cu, C₂H₆ are ionic, metal, and organic compounds, respectively.
CaCl₂ is formed by a metal (Ca) and a non-metal (Cl). Due to the difference in their electronegativities, they form ionic compounds. These compounds tend to have high melting and boiling points and conduct electricity in aqueous solution.
Cu is a transition metal. It is a good electric and heat conductor, which is why it is used in cables. It also has high melting and boiling points.
C₂H₆ (ethane) is a hydrocarbon, that is, an organic compound (formed by at least C and H). They are bad conductors and have low melting and boiling points.
CaCl₂, Cu, C₂H₆ are ionic, metal, and organic compounds, respectively.

Which weak acid would be best to use when preparing a buffer solution with a pH of 9.80?A. An acid with Ka = 7.9 times 10-12.B. An acid with Ka = 2.0 times 10-5.C. An acid with Ka = 2.5 times 10-7.D. An acid with Ka = 1.6 times 10-6.E. An acid with Ka = 2.0 times10-8.F. An acid with Kg = 1.3 times 10-10.
Answer:
An acid with Kg = 1.3 times 10-10.
Explanation:
The formula for pH of a buffer solution is as follows
pH = pKa + log [ A⁻ ] / [ HA ]
HA is acid concentration and A⁻ is concentration of conjugate base .
Generally the the second term is very small so neglecting this figure
pH = pKa
9.8 = pKa
If Ka = 10⁻¹⁰ x 1.3
pKa = - log ( 10⁻¹⁰ x 1.3 )
= 10 - log 1.3
= 9.8 approx .
Hence option F is correct .

1. Water will evaporate______ acetone
2. The vapor pressure of acetone is__________ than that of water at the same temperature.
3. This is because the intermolecular forces between acetone molecules are ___________than those between water molecules.
Answer:
1. more slowly than
2. larger than
3. weaker
Explanation:
Acetone molecules are bonded by very weak intermolecular forces when compared to that of the hydrogen bond between water molecules. This makes it very easy for acetone molecules to vaporize easily into its gaseous state, much more faster than water molecules (since the acetone molecules need a lesser amount of energy to break these bonds). Also, the boiling point of liquid acetone is much lower than that of water, meaning that it has a higher vapor pressure than that of water.

Answer:
Tvfbggbtb
Explanation:
Arrange these compounds by their expected boiling point.Highest boiling pointLowest boiling pointCH3OH, CH3Cl, CH4
Answer:
CH3OH > CH3Cl > CH4
Explanation:
The boiling point of a compound depends on the nature and magnitude of intermolecular forces acting between its molecules.
Methanol contains the -OH group, hence hydrogen bonds are dominant intermolecular forces in the compound. Presence of hydrogen bonds increases the boiling point of a substance, hence methanol has the highest boiling point followed by chloromethane which has dipole-dipole interaction as dominant intermolecular forces and methane having only weak dispersion forces as dominant intermolecular forces.

Answer:
C) 1.15 × 10⁻⁷ mm
Explanation:
Step 1: Given data
Average distance between nitrogen and oxygen atoms: 115 pm
Step 2: Convert the distance to meters (SI base unit)
We will use the conversion factor 1 m = 10¹² pm.
115 pm × (1 m/10¹² pm) = 1.15 × 10⁻¹⁰ m
Step 3: Convert the distance to millimeters
We will use the conversion factor 1 m = 10³ mm.
1.15 × 10⁻¹⁰ m × (10³ mm/1 m) = 1.15 × 10⁻⁷ mm

On average, what mass of blood does the heart pump with each heart beat?
Answer:
5.265L/body ; 68.9×10³ kg / beat
Explanation:
Given the following :
Resting pulse rate = 81 beats / minute
Amount of blood pumped per beat = 65mL = (65 / 1000)L = 0.65L
Density of blood = 1060 kg/m^3
Circulation time = 1 minute for a person at rest
A.) How much blood is in the body?
Resting pulse rate × amount of blood pumped per beat * circulating time
(81 beat / min) × 0.65L/beat * 1minute / body = 5.265L / body
B.) b. On average, what mass of blood does the heart pump with each heart beat?
0.065L/beat * 1m³/1000L= 0.000065 m³ / beat
From density = mass / volume ;

Complete Question
A nearly flat bicycle tire becomes noticeably warmer after it has been pumped up. Approximate this process as a reversible adiabatic compression. Take the initial pressure and temperature of the air before it is put in the tire to be Pi = 1.00 bar and Ti = 298 K. The final volume of the air in the tire is Vf= 1.50 L and the final pressure is Pf = 5.00 bar. Calculate the final temperature of the air in the tire.
Assume that Cv,m = 5R/2
Answer:
The value is [tex]T_f = 471.978 \ K[/tex]
Explanation:
From the question we are told that
The initial pressure is [tex]P_i = 1.00 \ bar[/tex]
The initial temperature is [tex]T_i = 298 K[/tex]
The final volume is [tex]V_f = 1.50 \ L[/tex]
The final pressure is [tex]P_f = 5.0 \ bar[/tex]
Generally the equation for reversible adiabatic compression is
[tex]P_i V_i^{\gamma} = P_f V_f^{\gamma} [/tex]
Generally from the ideal gas equation we have that
[tex]PV = n RT[/tex]
=> [tex] V = \frac{n RT}{P}[/tex]
So
[tex]P_i *[ \frac{n RT_i}{P_i}]^{\gamma} = P_f [ \frac{n RT_f}{P_f}]^{\gamma}[/tex]
=> [tex]P_i ^{1 - \gamma} * T_i ^{\gamma} = P_f ^{1-\gamma} * T_f^{\gamma}[/tex]
=> [tex]T_f ^{\gamma} = \frac{ P^{1 - \gamma * T_i^{\gamma}}}{ P_f ^{1 - \gamma}}[/tex]
=> [tex]T_f =[ \frac{ P_i ^{1 - \gamma} * T_i^{\gamma}}{P_f^{1 - \gamma}}]^{\frac{1}{\gamma} }[/tex]
=> [tex]T_f = T_i * [\frac{P_i}{P_f} ]^{\frac{1- \gamma}{\gamma}[/tex]
Here [tex]\gamma[/tex] is a constant mathematically represented as
[tex]\gamma = \frac{C_{P,m}}{C_{V, m}}[/tex]
Here
[tex]C_{P,m}} [/tex] is the molar heat capacity at constant pressure
and [tex]C_{V,m}} [/tex] is the molar heat capacity at constant volume given as
[tex]C_{V,m}} = \frac{5R}{2} [/tex]
Generally [tex]C_{P,m}} [/tex] for an ideal gas is mathematically represented as
[tex]C_{P,m}} = R +C_{V,m}} [/tex]
So
[tex]\gamma = \frac{\frac{5R}{2} + R}{ \frac{5R}{2} }[/tex]
=> [tex]\gamma = \frac{7}{5} [/tex]
So
=> [tex]T_f = T_i * [\frac{P_i}{P_f} ]^{\frac{1- \frac{7}{5}}{ \frac{7}{5}}[/tex]
=> [tex]T_f = 298 * [\frac{1}{5} ]^{\frac{1- \frac{7}{5}}{ \frac{7}{5}}[/tex]
=> [tex]T_f = 471.978 \ K[/tex]
The Final temperature of the air in the tire = 471.978k
Given data :
Initial pressure ( [tex]P_{i}[/tex] ) = 1.00 bar
Initial temperature ( [tex]T_{i}[/tex] ) = 298 K
Final volume of air ( [tex]V_{f}[/tex] ) = 1.50 L
Final pressure ( [tex]P_{f}[/tex] ) = 5.00 bar
Assume Cvm = 5r / 2 ( missing data )
Determine the final temperature of the air in the tire
Applying the equation for a reversible Adiabatic compression and general ideal gas equation
[tex]Pi * [ \frac{nRTi}{Pi} ] \alpha = Pf * [ \frac{nRTf}{Pf}] \alpha[/tex] ---- ( 1 )
Resolving equation ( 1 )
[tex]final temperature = Ti * [ \frac{Pi}{Pf}]^{\frac{1-\alpha }{\alpha } }[/tex] ------- ( 2 )
where [tex]\alpha[/tex] ( mathematical constant ) = ( Cpm / Cvm ) --- ( 3 )
Cpm = molar heat capacity at constant pressure = R + Cvm
Cvm = molar heat capacity at constant volume = 5r / 2
∴ Equation ( 3 ) becomes
[tex]\alpha[/tex] = [tex]\frac{7}{5}[/tex]
Final step : Determine the final temperature of the air in the tire
Input values back into equation ( 2 )
[tex]final temperature = 298 + [\frac{1}{5}] ^{\frac{1-\frac{7}{5} }{\frac{7}{5} } }[/tex]
= 471.978 K
Hence we can conclude that the final temperature of the air in the tire is 471.978 K

If 33.6 g of NO and 26.9 g of O₂ react together, what is the mass in grams of NO₂ that can be formed via the reaction below? 2 NO (g) + O₂ (g) → 2 NO₂ (g)
Answer:
If 33.6 g of NO and 26.9 g of O₂ react together, 51.52 grams of NO₂ can be formed.
Explanation:
You know: 2 NO (g) + O₂ (g) → 2 NO₂ (g)
By stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of reagent and product participate in the reaction:
NO: 2 moles O₂: 1 moleNO₂: 2 molesBeing:
N: 14 g/moleO: 16 g/molethe molar mass of the compounds participating in the reaction is:
NO: 14 g/mole + 16 g/mole= 30 g/moleO₂: 2*16 g/mole= 32g/moleNO₂: 14 g/mole + 2*16 g/mole= 46 g/moleThen, by stoichiometry of the reaction, the following amounts of reactant and product participate in the reaction:
NO: 2 moles* 30 g/mole= 60 gO₂: 1 mole* 32g/mole= 32 gNO₂: 2 moles* 46 g/mole= 92 gThe limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction. When the limiting reagent is finished, the chemical reaction will stop.
You can apply the following rule of three to determine the limiting reagent: if by stoichiometry 60 g of NO react with 32 g of O₂, 33.6 g of NO with how much mass of O₂ will it react?
[tex]mass of O_{2}=\frac{33.6 grams of NO*32 grams of O_{2} }{60 grams of NO}[/tex]
mass of O₂= 17.92 grams
But 17.92 grams of O₂ are not available, there are 26.9 grams available. Since it has more mass than it needs to react with 33.6 grams of NO, NO will be the limiting reagent.
Then you apply the following rule of three: if by reaction stoichiometry 60 grams of NO form 92 grams of NO₂, 33.6 grams of NO how much mass of NO₂ does it form?
[tex]mass of NO_{2}=\frac{33.6 grams of NO*92 grams of NO_{2} }{60 grams of NO}[/tex]
mass of NO₂= 51.52 grams
If 33.6 g of NO and 26.9 g of O₂ react together, 51.52 grams of NO₂ can be formed.

Answer:
Following are the explanation of the Rube Goldberg device:
Explanation:
According to the Rube Goldberg devices, which conform with "the energy conservation law," choose a chain of events to carry out such a basic task differently, for this unit, a range of instant theatrical resources are converted into possible energy. It is also responsive to an energy conservation law.
It is the unit that produces theatrical power when quartz falls off from the roof. Instead, its marble hits or falls into a plastic bottle, its velocity converted into potential energy which lifts its soda bottle. Its next marble, when the stone came in contact with it, can pass angular momentum to some other marble. Its gravitational force of quartz drops.
