Answers
Answer:
Step 1: CCl4 + 2(HF) --> CCl2F2 + 2(HCl)
Step 2: CCl2F2: 121 g/mol CCl4: 154 g/mol
Step 3: 25.1 g
Step 4: 50.6%
Explanation:
Step 1: Write a balanced equation
The unbalanced form of the equation is just what the problem tells you in the beginning: Freon is synthesized from CCl4 with HF. HCl is also made as a byproduct. This means that our equation will be:
CCl4 + HF --> CCl2F2 + HCl
This equation is clearly unbalanced, as there are different numbers of atoms on either side.
Starting Atoms:
(The arrow shows what is on either side of the reaction arrow)
C: 1 --> 1
Cl: 4 --> 3
H: 1 --> 1
F: 1 --> 2
Let's first try adding a coefficient of 2 to HCl.
Coefficient One:
C: 1 --> 1
Cl: 4 --> 4
H: 1 --> 2
F: 1 --> 2
However, now the H (as well as the F) are out of balance on the left side of the arrow. Luckily, putting a coefficient of 2 in front of HF balances the equation completely.
Coefficient Two:
C: 1 --> 1
Cl: 4 --> 4
H: 2 --> 2
F: 2 --> 2
This means that the balanced equation is:
CCl4 + 2(HF) --> CCl2F2 + 2(HCl)
Step 2: Calculate the Molar Masses
To find the molar masses, we simply add up all of the individual atomic masses.
CCl2F2: (12.0)+2(35.5)+2(19.0) = 121 g/mol
CCl4: (12.0)+4(35.5) = 154 g/mol
Step 3: Calculate the Theoretical Yield in Grams
We can now put together the previous steps. You typically need to figure out which molecule is the limiting reactant, but as they have only given you one initial mass, we can assume that CCl4 will be the LR. Essentially, the next step is to do several conversions to turn this reactant gram value into a product value. We will go from g of reactant to moles of reactant (using its molar mass), then to moles of product (with the balanced equation), and finally, to grams of product (using the other molar mass):
[tex]\frac{31.9g}{1} *\frac{1molCCl4}{154g} *\frac{1molproduct}{1molCCl4} *\frac{121g}{1molproduct}=25.1g[/tex]
This results in 25.1 g of product as our theoretical yield. This amount is the absolute maximum amount of product that could possibly be made from the amount of starting materials that we put in.
Step 4: Calculate the Percent Yield
This is probably the easiest step. All we have to do is use the following equation, and we will have our answer:
[tex](\frac{created}{expected})*100=yield[/tex]
The created value is what is given in the problem itself: 12.7 g
The expected amount is our theoretical yield value that we just calculated: 25.1 g
Substituting this into the equation, our percent yield is just over half at about 50.6%. Keep in mind that a yield of 100% is just about impossible due to human error, things being left on glassware, etc.

In the reaction between copper and silver nitrate, 95.3 g of silver and 82.9g of copper nitrate are produced. How much of each reactant was used?
Answers
Reaction
2AgNO₃ + Cu ⇒ Cu(NO₃)₂ + 2Ag
mol silver (Ag): 95.3 : 108 g/mol = 0.882
mol copper nitrate (Cu(NO₃)₂): 82.9 : 187.5 g/mol = 0.441
mol Ag = 2 x mol Cu(NO₃)₂, so 0.441 being the mole basis of the reactants
mol Cu = 0.441
mass Cu = 0.441 x 63.5 g/mol = 28 g
mol AgNO₃ = 0.882
mass AgNO₃ = 0.882 x 170 g/mol = 149.94 g

Answers
Answer: Aluminum reacts with oxygen to produce aluminum oxide
Explanation:
The conversion factor for the given chemical equation is 2:4.
To convert from moles of aluminum to moles of aluminum oxide, we can use the balanced chemical equation: [tex]4 Al+ 3 O_2\rightarrow 2 Al_2O_3[/tex]
The coefficients in the balanced equation can be used as conversion factors. In this case, we want to find the ratio of moles of aluminum oxide to moles of aluminum.
From the balanced equation, we can see that:
- For every 4 moles of aluminum, we get 2 moles of aluminum oxide.
So, the proper conversion factor has 2 moles of aluminum oxide in the numerator and 4 moles of aluminum in the denominator.
Therefore, the conversion factor is:2 moles of aluminum oxide : 4 moles of aluminum.

Answers
The activation energy for this reaction is 169 kJ/mol. ΔE for this reaction is +27 kJ/mol.
Activity energy is the minimum energy required by the reactants to occur the reaction.
AE is the energy difference between products and reactants. It is also obtained as the difference between activation energies of forward and reverse reactions.
Decomposition of HI (g) is the reverse reaction of given reaction. Calculate the activation energy for reverse reaction as follows:
ΔE = activation energy of forward reaction - activation energy of reverse reaction +27 kJ/mol = 169 kJ/mol - activation energy of reverse reaction
Activation energy of reverse reaction =169 kJ/mol - 27 kJ/mol = 142 kJ/mol
Therefore, the activation energy for the decomposition of HI = 142 kJ/mol

The inside of a basketball has a pressure of 0.476 atm at 25.0°C. The pressure inside the ball if the temperature is decreased to 20.0°C is 0.484 atm.
What do you mean by the pressure ?The term pressure is defined as the amount of force applied perpendicular to the surface of an object per unit area. The symbol for it is "p" or P.
There are two basic types of pressure are absolute and gauge - distinguished by what pressure they are compared to, which is called the reference pressure.
Given:
P1 = 0.476 atm
T1 = 25.0°C = 298K
P2 = ?
T2 = 20.0°C = 293 K
P1T1 = P2T2
By putting these values in above equation and we get,
P2 = P1T1/ T2
= 0.476 ×298 / 293
= 0.484 atm
Thus, the pressure inside the ball if the temperature is decreased to 20.0°C is 0.484 atm.
