You have two distinct gaseous compounds made from element X and element Y. The mass percents are as follows: Compound I: 30.17% X, 69.83% Y Compound II: 63.35% X, 36.65% Y In their natural standard states, element X and element Y exist as gases. (Monatomic? Diatomic? Triatomic? That is for you to determine.) When you react "gas X" with "gas Y" to make the products, you get the following data (all at the same pressure and temperature): 1 volume "gas...

In lab, we noted that pressure (which should be the same for both gases) is a product of the strength of the collision times the frequency of collisions. The strength is proportional to mv, and the frequency is proportional to v. If we take the mass of hydrogen to be 4 kg and the speed to be 3 m/s (yes - these numbers are ridiculous for a molecule of gas - but the goal here is to focus on concepts...

1.) N2 and Kr are sealed in two separate identical jars at STP. Compare the average kinetic energies and average molecular velocities of these gases. 2.) When a metal rod, mass 21.9 g, heated to 85 C is placed into a coffee-cup calorimeter containing 200.0 ml of water at 20.0 C, the equilibrium temperature achieved by the system is 21.5 C. What is the heat capacity of metal?
