Rutherford’s experiments included deflection of D-particles. As a result of its experiments, what did he conclude about the atom?

The stopcock connecting a 2.95 L bulb containing nitrogen gas at a pressure of 2.75 atm, and a 4.87 L bulb containing carbon dioxide gas at a pressure of 2.15 atm, is opened and the gases are allowed to mix. Assuming that the temperature remains constant, the final pressure in the system is

22) Consider the reaction if 33.2 g of K2CO3 is produced from reacting 40.0 g KO2 with 25.0 L of CO2 (at STP). The molar mass of KO2 = 71.10 g/mol and K2CO3 = 138.21 g/mol. (4 points)

4 KO2(s) + 2 CO2(g) → 2 K2CO3(s) + 3 O2(g)


a. How many moles of CO2 are available?






b. How much K2CO3 can be produced from the 33.2 g of KO2 that is available?
