1. Assuming pressure remains constant, calculate the final volume in each of the following cases: a) A volume of 35.0 mL of gaseous hydrogen is heated from 20 °C to 120 °C;b) A volume of 15 L of air is chilled from 80 °C to -25 °C.
2. The temperature of a room whose volume is 8.95 x 104 L goes from 20 °C to 30 °C. What volume of air will the room lose following this rise in temperature?
3. Calculate the initial volume of a sample of a gas if its final volume is 344 mL after being heated from -10 °C to 40 °C.
A reaction has a theoretical yield of 8.83 g of ammonia. the reaction gives off 10.24 L of ammonia measure at 52*C and 105.3kPa what was the percent yield of the reaction?
Consider an experimental run at 273 rm K where the initial number of moles (n_1) is actually 1.00 rm mol, and the final number of moles (n_2) is 2.00 rm mol.
Consider the following reaction at constant P. Use the information here to determine the value of ?Ssurr at 355 K. Predict whether or not this reaction
A 12.4 g sample of CaCl2 is dissolved in 112 g of water, with both substances at 25.0°C. Calculate the final temperature of the solution assuming no heat lost to the surroundings and assuming the solution has a specific heat capacity of 4.18 J/°C·..
spontaneous chemical reactions produce products which are more energetically stable than the reactants which form them. A strong acid reacts with a strong base to produce water and the free ions of a salt.
