What determines the amount of chemical energy a substance has?
The amount of chemical energy a substance has is determined by the types and arrangement of atoms and molecules in that substance. The energy is stored within the chemical bonds between these atoms and molecules. The strength of these bonds and the potential energy stored in them determine the amount of chemical energy.
The amount of energy needed to cause a chemical reaction to occur is the?
The amount of energy necessary to cause a chemical reaction to occur is called activation energy.
The amount of energy available to do work after a chemical reaction has occurred is called?
Chemical energy
What is the amount of energy needed to get a chemical reaction started known as?
activation energy
The amount of energy in a chemical that can do useful work is called?
This would be its chemical potential energy, of course it depends on what other chemical(s) it is reacting with, such as oxygen.
What are the factors that affect chemical energy?
1. mass 2. atomic bonds 3.amount of neutrons
What factors influence the amount of energy that different places on earth receives from the sun?
The main factor that influences the amount of energy that different places on Earth receive from the sun is the places location. The closer it is to the equator the more sun energy it will receive.
Whar factors influence nonbasal energy needs?
Basal Energy expenditure is the amount of energy needed by the body for maintenance of life when a person is at complete digestive, physical, mental, thermal, and emotional rest. The factors that influence non basal energy needs are lean body mass, growth periods, body temperature, and hormonal status.

Factors that influence heat production?
energy, sun
Lighting a match changes chemical energy into heat and light The total amount of energy?
Lighting a match changes chemical energy into heat and light. The total amount of energy
Compare the total amount of energy before and after physical and chemical changes?
Physical Change-- Same amount of energy, but in different form Chemical Change-- Different amount of energy, and in a different form
What are the 5 important factors that influence the rate of a chemical reaction?
Temperature Surface area/phase of reactants Concentration of reactants Presence of catalyst Activation energy of reaction
What does the amount of energy affect during a chemical reaction?
A chemical reaction need an activation energy to start.
What is the role of energy in chemical reations?
All chemical reactions need a certain amount of activation energy to get started.
