Why is heat often added to a chemical reaction performed in a laboratory?

By heating you are adding energy!!!
Energy is needed to start a reaction ; it is called ther Activation Energy'.
If you use a Bunsen Burner in the lab. to heat reactants.. Then some of the heat is going in (endothermic) to start the reaction. The heat you feel from the Bunsen Burner is waste energy; it is not going in to start the reaction.
Remember ;
Bond breaking is endothermic (heat/energy to go in )
Bond making is exothermic ( heat / energy is given off) ;the reaction might feel warm., without any applied energy.
Other forms of energy that can be used in achemical reaction are ;- Electricity, Light, Sound, and Mechanical (stirring).

∙ 13y ago-to allow greater number of reactants to pass over the activation energy
-to compensate for the natural tendency of energy to disperse
-to increase the rate at which reactants collide

If heat must be added to a chemical reaction for the reaction to take place the reaction is?
Endothermic reactions need heat. Exothermic reactions give off heat.
Chemical energy is energy that is?
added to a reaction in the form of heat.
Adding magnesium metal to hydrochloric acid chemical?
it is a chemical reaction because when the two are added together it creates a new substance so therefor it is a chemical reaction
Why are reactants important in a chemical reaction?
Reactants are added into the equation to form the chemical reaction. Reactants are substances that are changed into products. Without these reactants, there would be no formula, resulting in no product.
A chemical reaction in which a double bond of an unsaturated compound is broken and atoms are added at the point where the bond is broken?
The chemical reaction is the H2O bond with O2.
Which component is affected when a catalyst is added to a chemical reaction?
The component affected when a catalyst is added to a chemical reaction is the reactants. The purpose of a catalyst is to speed up a reaction.
Should heat be added for a chemical reaction to take place?
If the reaction is endothermic in nature then heat should be added to it,otherwise all chemical reaction neddn't heat always.
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is a Exothermic b Reactant c Balanced d Endothermic?
If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is endothermic.
If heat must be added to a chemical reaction for the reaction to take place the reaction is?
Endothermic reactions need heat. Exothermic reactions give off heat.
What chemical reaction involved in salted fish?
Salting is not a chemical reaction; simple, table salt is added to fish or another material.
Chemical energy is energy that is?
added to a reaction in the form of heat.
What can a reaction occurs to added to break bonds?
Any chemical reaction need an activation energy.
Would a chemical reaction occur if calcium is added to magnesium chloride?
Any reaction occur.
Element used to speed up chemical reactions?
Anything that is added to a chemical reaction that's intended to speed up the reaction - is a catalyst.
Adding magnesium metal to hydrochloric acid chemical?
it is a chemical reaction because when the two are added together it creates a new substance so therefor it is a chemical reaction
What chemicals can be added to Coca-Cola to cause a chemical reaction?
Carbohydrates are added to the coca cola and mentos which react together to cause a reaction.
What is a catayst?
In chemistry a catalyst is a substance which, when added to other substances, allows them to change while itself remaining unchanged.
