HW by group. Answer in 1 whole paper.
1.) CaC2 (s) +2H2O (l) --> C2H2 (g) + Ca (OH)2 (g)
Pt = 738 torr
V = 523 mL
T = 23° C
PH2O = 21 torr
Pt = PC2H2 + PH2O
Find the mass of C2H2
2.) A mixture of CO2 and Kr weighs 35.0g and exerts a pressure of 0.708 atm in its container. Since Kr is expensive, you wish to recover it from the mixture. After the CO2 is completely recovered by adsorption with NaOH(s), the pressure in the container is 0.250 atm. Show that the amount of CO2 and Kr originally present were 17.2g and 17.8g respectively.STR
