1. Consider the following equation: 4C3H5(NO3)3(s) â 12CO2(g) + 10H2O(g) + 6 N2(g) + O2(g) MW C3H5(NO3)3(s) = 227.1 g/mol 205 g of C3H5(NO3)3 is reacted. Assume reaction goes to completion and all the product gases are collected at 195.0 Co. The pressure is 0.95 atm. What is the total volume of the gases?
2.Which of the following is a TRUE statement about gas?
Gas particles exert a pressure when they hit the sides of the container. |
In general, doubling the pressure of a gas doubles its volume. |
Because the molecules have small distances between them compared to their size, they can't be compressed |
Hold the volume constant and decrease temperature |
3.One mole of oxygen gas is at one atmosphere of pressure and 10 oC. How can a scientist increase the pressure of the gas?
Decrease the temperature and hold volume constant |
Increase the volume constant and decrease the temperature |
Decrease the volume and increase the temperature |
hold temperature constant and increase the volume |
