Technically, it isn't "heat" that makes a chemical reaction happen. "Heat" is merely the flow of energy from one place to another. It is the energy itself that causes a reaction to occur. As an increase in temperature occurs, there is an increase in the energy in a group of molecules by making them mover around faster and bum into each other more. This energy is called "Activation energy", and is defined as the amount of energy required to make the reaction start and carry on spontaneously. Higher activation energy implies that the reactants need more energy to start than a reaction with a lower activation energy.
With that being said, activation energy is the answer

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 chemical reaction called where water is removed during the reaction?
This chemical reaction is called dehydration.
What are the materials you have at the beginning of a chemical reaction called?
The starting materials in a chemical reaction are called reactants.
The smallest amount of a fissionable material that will give a self-sustaining chain reactions is called the?
The smallest amount of a fissionable material that will produce a self-sustaining chain reaction is called the critical mass. This mass of affected by geometry and other factors such as temperature, pressure, and moderator.
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
The minimum amount of energy needed to start a chemical reaction is called?
The activation energy.
What is proteins that reduce the amount of energy needed to start a chemical reaction are called?
enzymes
What is the amount of energy a reaction needs to take place?
The amount of energy a reaction needs to take place is called activation energy. When this much energy is present, a chemical reaction can occur.
What chemical is formed in a chemical reaction?
The chemical or chemicals formed in a chemical reaction are called the product of the chemical reaction.
What is the chemical reaction called where water is removed during the reaction?
This chemical reaction is called dehydration.
The ratio of the actual amount you isolate from a chemical reaction compared to the amount you could theoretically isolate is called the?
Percent Yield
Is the amount of energy needed to cause a chemical reaction to start called activation energy?
yes
What is the starting substance in a chemical reaction is?
The substances you have at the beginning of a chemical reaction are called the reactants.
What is a reactant in science?
A chemical that undergoes a chemical reaction is called a reactant. The chemicals that are produced by a chemical reaction are called the products. So in a chemical reaction, reactants turn into products.
