When substances are dissolved in water, they can absorb or release heat. Describe how you would use a calorimeter to determine the amount of heat required or released to when 10 grams of sugar is dissolved in 100 grams of water. Describe how you would calculate the heat absorbed or released by the sugar with the data you collect. (Do no perform any calculations.)
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.
