Answer to Problem 7.63P
0.90atm | 4.0L | 265K | 1.4atm | 3.0L | 310K |
Explanation of Solution
The combined
Given that
Initial volume, V1 = 4.0L
Initial temperature, T1 = 265K
Initial pressure, P1 = 0.90atm
Final temperature, T2 = 310K
Final volume, V2 = 3.0L
Put the values in the above equation.
The final pressure of gas that is P2 = 1.4atm
Thus,
a. | 0.90atm | 4.0L | 265K | 1.4atm | 3.0L | 310K |

Answer to Problem 7.63P
1.2atm | 75L | 700mmHg | 110L |
Explanation of Solution
The combined gas law is used to determine the unknown values. The combined gas law includes the change in pressure-temperature and the volume of the gas. This relation is represented as
Given that
Initial volume, V1 = 75L
Initial temperature, T1 =
Initial pressure, P1 = 1.2atm
Final pressure, P2 = 700mmHg
Final temperature, T2 =

Answer to Problem 7.63P
200mmHg | 125mL | 298K | 100mmHg | 0.62L | 740K |
Explanation of Solution
The combined gas law is used to determine the unknown values. The combined gas law includes the change in pressure-temperature and the volume of the gas. This relation is represented as −
Given that −
Initial volume, V1 = 125mL
Initial pressure, P1 = 200mmHg
Initial temperature, T1 = 298K
Final pressure, P2 = 100mmHg
Final volume, V2 = 0.62L
Put the values in the above equation.
The final volume of gas that is T2 = 740K
The final table is
200mmHg | 125mL | 298K | 100mmHg | 0.62L | 740K |

The chemical equation for the net ionic reaction of NaCl and KCl with silver nitrate, AgNO3, is shown below. Ag+(aq) + Cl(aq) → AgCl(s) The total mass of the NaCl/KCl mixture is 1.299 g. Adding 50.42 mL of 0.381 M solution precipitates out all of the Cl-. What are the masses of NaCl and KCl in the mixture?

- Identify the missing starting materials/ reagents/ products in the following reactions. Show the stereochemistry clearly in the structures, if any. If there is a major product, draw the structures of the major product with stereochemistry clearly indicated where applicable. Show only the diastereomers (you do not have to draw the pairs of enantiomers). If you believe that multiple products are formed in approximately equal amounts (hence neither is the major product), draw the structures of the products, and show the detailed mechanism of these reactions to justify the formation of the multiple products. If you believe no product is formed, explain why briefly. (6 mark for each, except f and g, which are 10 mark each)arrow_forward3.
