A 68.0 kg person uses 214 kJ of energy to walk 1.00 km. This energy comes from “burning" glucose (Burning 1.00 g of glucose produces 15.7 kJ of heat.), but only about 30.0% of the heat of combustion of glucose can be used for propulsion. The rest is used for other bodily functions or is "wasted" as heat. Assuming that a "sugar-coated" breakfast cereal contains 29.0% sugar (which can be considered glucose) and no other energy source, calculate how many grams of cereal provide enough energy to walk 1.00 km.

A 6.61g sample of an unknown salt (MM=116.82g//mol) is dissolved in 150.00g water in a coffee cup calorimeter. Before placing the sample in the water, the temperature of the salt and water is 23.72 C. After the salt has completely dissolved, the temperature of the solution is 28.54 C. Given that 156.61 g of solution increased in temperature by 4.82 °C, what quantity of heat, in J, was gained by the solution? Assume the specific heat of the solution is the same as water, 4.184 J/g• °C.
The heat released when one mole of water is formed from the elements is 1,198 kJ. An experiment was conducted that permitted water to form in this manner, and the heat was contained in 2.0 liters of water. The water temperature before the reaction was 34.5°C, and after the reaction it had risen to 52.0°C. How many moles of water were formed? (The specific heat of water is 4.184 J/g·°C.)Answer: 0.12 mole (Can you explain how?)

A 50.8 g sample of an unknown metal was heated to 700.0 ˚C then placed into 100.0 g of water (specific heat: 4.184) initially at 25.0 ˚C. The water and the unknown metal reach equilibrium when both are at 78.3 ˚C. What was the specific heat of the unknown metal?
q represents the change in heat of a reaction or substance. The units of q are Joules (J) or kilojoules (kJ). For a well understood substance, we can calculate the specific heat which relates the mass of the substance in grams to the amount of heat in J required to raise that amount a certain temperature. We call that specific heat. The specific heat (Cs) of water is stated in the following way: C s ( H 2 O ) = 4.186 J g ∘ C This means that it takes 4.186 J of energy to raise the temperature of 1g of water by 1ºC. The relationship between q and Cs for a given substance is where m is mass (g) and ∆T is the change in temperature in ºC (final temp - initial temp). Calculate the heat change (q) in J when 4.297 grams of water is cooled from 3.967 ºC to -2.902 ºC. Enter your answer with one decimal place (tenths). Pay careful attention to the sign of your answer. The sign of ∆T is always the same as the sign for q.
