Imagine being able to use your computer to make phone calls with the help of special software and a microphoneâand bypassing your phone company and their charges.
So O2 has zero of heat of formation (or enthalpy of formation). The enthalpy of a reaction is defined like this: H = Hproducts-H reactants. The enthalpy of reaction in this case, is the same as the heat of combustion. Hproducts is obtained summing the heats of formation.
Study the equation. First, you should look at the equation to get a sense of what you need to do to find the specific heat. Let's look at this problem: Find the specific heat of 350 g of an unknown material when 34,700 Joules of heat are applied, and the temperature rises from 22ÂºC to 173ÂºC with no phase change.
