A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The cylinder has a piston that moves in or out, as necessary, to keep a constant pressure on the mixture of 1 atm. The cylinder is also submerged in a large insulated water bath. (See sketch at right.) From previous experiments, this chemical reaction is known to absorb 176. kJ of energy. The temperature of the water bath is monitored, and it is determined from this data that 377. kJ of heat flows out of the system during the reaction. Is the reaction exothermic or endothermic? Does the temperature of the water bath go up or down? Does the piston move in or out? Does the gas mixture do work, or is work done on it? How much work is done on (or by) the gas mixture?

A coin dealer, offered a rare silver coin, suspected that it might be a counterfeit nickel copy. The dealer heated the coin, which weighed 16.0 g to 100°C in boiling water and then dropped the hot coin into 29.0 g of water at T = 18.0°C in an insulated coffee-cup, and measured the rise in temperature. If the coin was really made of silver, what would the final temperature of the water be (in °C)? (for nickel, s = 0.445 J/g°C; for silver, s = 0.233 J/g°C )
Nadine needs to heat 2.0 L of water from 15ᵒC to 90ᵒC. A) how much energy is needed to heat the water? B) If burning methane (CH4) releases 810 kJ/ mole, what mass of methane will be burned? C) What volume of oxygen at 20ᵒC and 725 mmHg will be consumed by the combustion of methane? You will need a balanced equation and a gas law for C and the specific heat capacity of water is 4.184J/gᵒC.
At 25 °C and 765.6 torr, a sample that is a gaseous compound containing carbon, hydrogen, and oxygen occupies a volume of 0.582 L. A mass of 1.103 g of this sample was burned in a bomb calorimeter, producing 1.294 g of liquid water and 2.108 g of gaseous carbon dioxide. The heat produced from the combustion raised the temperate of the calorimeter from 25 °C to 31.94 °C. a.) What is the percent elemental composition by mass of the unknown sample. b.) Determine the empirical formula of the sample.
A hot, 3.00 g metal ball at 140.oC was placed in 8.0 mL of cold water at 12oC. The specific heat capacity of the metal is 3.3 J/g◦C. What was the final temperature of the water? [Hint: Look up the density of water.]

1. The formation of gaseous phosphorus trichloride is shown below: P4 (g) + 6 Cl2 (g) → 4 PCl3 (g) ΔH = -1207 kJ/mol If 4.30 kJ of heat are released as the formation reaction above proceeds, how many milliliters of gaseous phosphorus trichloride, measured at 35°C and 712 torr, will be produced?
An industrial process for manufacturing sulfuric acid, H2SO4, uses hydrogen sulfide, H2S, from the purification of natural gas. In the first step of this process, the hydrogen sulfide is burned to obtain sulfur dioxide, SO2. 2H2S(g) + 3 O2(g) → 2 H2O(l) + 2 SO2(g); ∆H = -1124 kJ. The density of sulfur dioxide at 25 °C and 1.00 atm is 2.62 g/L, and the molar heat capacity is 30.2 J/mol °C. a) How much heat would be evolved in producing 1.00 L of SO2 at 25 °C and 1.00 atm? b) Suppose heat from this reaction is used to heat 1.00 L of SO2 from 25 °C to 500 °C for its use in the next step of the process. What percentage of the heat evolved is required for this?
One method of generating electricity is by burning coal to heat water, which produces steam that drives an electric generator. To determine the rate at which coal is to be fed into the burner in this type of plant, the heat of combustion per ton of coal must be determined using a bomb calorimeter. When 1.00 g of coal is burned in a bomb calorimeter (as shown), the temperature increases by 1.48 °C. If the heat capacity of the calorimeter is 21.6 kJ/°C, determine the heat produced by combustion of a ton of coal (2.000 × 103 pounds).
