How is energy important to chemistry?

Answer 1

First: as a catalyst. Energy is usually required to get a chemical reaction to start. If you imagine it one molecule at a time, there are charged particles involved, and when the configuration is changed there will be a change in energy: either energy released or energy put into the system. So a catalyst, like when you heat a beaker to speed up a reaction, is needed to initiate or speed up a reaction. The heat is thermal energy, which can be needed to bring about chemical change. Second: as a release of energy. Usually, the end-configuration of molecules results in a drop in energy, and energy is released. Usually it is released as heat (thermal energy) or light (radiation, or radiant energy). Think of a bomb, it releases a lot of energy from the chemical reaction very quickly.

Answer 2

There are many kinds of energy: chemical energy from fossil fuels, electrical energy distributed by a utility company, radiant energy from the Sun, and nuclear energy from a reactor. The units of energy include ergs, joules, foot-pounds, and foot-poundals. Work and heat have the same units as energy, but are entirely different physical concepts.....

any other question just ask me.....

Answer 4

Energy is the capacity to do work. At least that is what my chemistry teacher says. I think the definition of energy is the ability to do work. The units of energy are Joules (J) and Calories (cal).

Answer 5

describe a typical day.then try to identify situations during the day in which chemistry somehow play apart

Answer 6

tt
Chemical reactions that absorb energy will not occur without the source of energy.
