How to Calculate Endothermic and Exothermic Reactions

Decomposition reactions are really the opposite of combination reactions. In , a single compound breaks down into two or more simpler substances (elements and/or compounds).

Students will explore the five types of reactions and observe each in the lab.

A law in chemistry, the , states, “In an ordinary chemical reaction, matter is neither created nor destroyed.” This means that you have neither gained nor lost any atoms during the reaction. They may be combined differently, but they’re still there.

When you write an equation for a chemical reaction, the two sides of the equation should — you need the same number of each kind of element on both sides. If you carry out a chemical reaction and carefully sum up the masses of all the reactants, and then compare the sum to the sum of the masses of all the products, you see that they’re the same.

A chemical equation represents the reaction. That chemical equation is used to calculate how much of each element is needed and how much of each element will be produced.

There are several different categories of Chemical Reactions.

Chemical equations must be balanced -- they must have the samenumber of atoms of each element on both sides of the equation. Asa result, the mass of the reactants must be equal to the mass ofthe products of the reaction. On the atomic scale, the followingequation is balanced because the total mass of the reactants isequal to the mass of the products.

The reason that all paper doesn't spontaneously burst into flames is that the activation energy of the match was required to start the process of the burning (also called a combustion reaction) which produced its own heat and allowed more paper to burn.

How to Calculate Endothermic and Exothermic Reactions

There are also several different types of chemical reactions based upon the types of compounds undergoing the reaction and the ways in which they react.

An example of an endothermic reaction is electrolysis.

It is possible to fill a balloon with a mixture of hydrogenand oxygen and find that no reaction occurs until you touch theballoon with a flame. The balanced equation for this reactiondescribes the relationship between the amounts of hydrogen andoxygen consumed and the water formed if or when this reaction isinitiated.

are examples of decomposition reactions.

There is no sequence of rules that can be followed blindly toget a balanced chemical equation. Manipulate the coefficientswritten in front of the formulas of the reactants and productsuntil the number of atoms of each element on both sides of theequation are the same.

That is the difference between endothermic and exothermic reactions.

This equation shows you what happens in the reaction, but it doesn’t show you how much of each element you need to produce the ammonia. To find out how much of each element you need, you have to balance the equation — make sure that the number of atoms on the left side of the equation equals the number of atoms on the right.

Anothercompletely different but common classification scheme recognizes fourmajorreaction types:

You know the reactants and the product for this reaction, and you can’t change them. You can’t change the compounds, and you can’t change the subscripts, because that would change the compounds.

Once you light the match which catches the paper on fire, thus providing the activation energy, the paper continues to burn by itself by reacting with they oxygen in the air until the paper is consumed.
