-Calorimetry Questions 1. A 24.6 g sample of nickel is heated to 110.0 °C and then placed in a coffee-cup calorimeter containing 125 g of water at a temperature of 23.00 °C. After the nickel cools, the final temperature of the metal and water is 24.83 °C. Assuming that no heat has escaped to the surroundings or has been absorbed by the calorimeter, calculate the specific heat of nickel. 2. When solutions of an acid and a base are mixed, heat is released. Using a coffee-cup calorimeter, 100.0 mL of 0.100 mol/L HCI are mixed with 100.0 mL 0.100 mol/L NaOH solution. The initial temperature of the solutions were 22.6 °C, and the temperature after mixing was 32.4 °C. Calculate the molar enthalpy of neutralization for the reaction: HCI (aq) + NaOH (aq) → NaCI (aq) + H,0 (1)

If you hold 3 grams of ice in your hand at room temperature, your hand will become cold. a) Is the reaction H,O(s) – H,O(1) endothermic or exothermic? b) In which direction does heat flow?
In order to break water into hydrogen and oxygen, water is heated to more than 500°C. Which kind of reaction is this and why? It is exothermic because heat needs to be released by the reactants to form the products. It is endothermic because heat needs to be released by the reactants to form the products It is exothermic because heat needs to be absorbed by the reactants to form the products. It is endothermic because heat needs to be absorbed by the reactants to form the products.
