UNDERSTANDING OF THERMOCHEMICAL

Part of chemistry that studies the changes of heat or
heat a substance that accompanies a chemical reaction or process and
physics called thermochemistry. Operationally related thermochemical
by measuring and interpreting passages of heat changes that accompany
chemical reaction, change of state, and the formation of solution.
Thermochemistry is the basic knowledge that needs to be given
or which can be obtained from chemical reactions, but also need to
as a knowledge base for the assessment of chemical bond theory and
chemical structure. The focus of the discussion is about the thermochemical
the amount of heat that can be generated by a certain number of reagents
and how to measure the heat of reaction.
So that more people understand the energy that accompanies change
a substance, it is necessary to answer the following questions:
1. What energy possessed by a substance?
2. What laws apply to the energy of a substance?
B. ACTIVITY

3. How to determine the amount of energy that accompanies a
reaction?
4. How does the energy of a substance can be measured?
5. How is the relationship between the energy liberated or absorbed
chemical changes in chemical bonding?
Thermochemistry is the first application of the law
thermodynamics of the chemical events that discuss the heat
that accompany chemical reactions.
To understand the thermochemical have discussed about:
(a) System, the environment, and the universe.
(b) The energy possessed by each agent.
(c) The law of conservation of energy.
