Bonus please ### Calorimetry Practice Problems#### Problem 7The heat of combustion of methane is 212.8 kcal per mole. How much heat will be produced in the combustion of 100.0 g of methane, CH₄?#### Problem 8A piece of metal with a mass of 75.5 g is heated to 84.5 ºC and added to 100.0 mL of water at 5.0 ºC. The final temperature of the mixture is 75.0 ºC. Find the specific heat of the metal in cal/gºC.#### Bonus ProblemCopper has a density of 8.94 g/cm³ and a specific heat of 0.090 cal/gºC. A cube of copper is heated from 10.5 ºC to 21.4 ºC. The cube of copper has dimensions of 5.00 cm. How much heat would the copper cube absorb?#### Problem 9When a 4.25 g sample of solid ammonium nitrate dissolves in 60.00 g of water in a coffee-cup calorimeter, the temperature drops from 22.0 ºC to 16.9 ºC. Calculate ΔH (in kJ/mol NH₄NO₃) for the solution process.\[ \text{NH}_4\text{NO}_3 (\text{s}) \rightarrow \text{NH}_4^+(\text{aq}) + \text{NO}_3^-(\text{aq}) \]*Assume that the specific heat of the solution is the same as that of pure water.*#### Problem 10Compound A is burned in a bomb calorimeter that contains 2500.0 g of water. If the combustion of 0.175 moles of this compound causes the temperature of the water to rise 45.0 ºC, what is the molar heat of combustion of compound A in kJ/mol? The heat capacity of water is 4.18 J/gºC.
