What happens to the equilibrium?

If it shifts right and be balanced but when we ass more product it word shift left?

Why does a chemical equation need to be balanced?

In order to show that mass is conserved during a reaction, a chemical equation must be balanced.

What can disturbance be?

It can be adding chemical, removing chemical, pressure/ volume, temperature change, and or a dilution.

What does the parenthesis mean in when they have a chemical element inside of it and outside of the parenthesis has a number?

It means whatever is inside of the parenthesis is multiplied by the number outside of the parenthesis.

What is Hydrocarbon reacts to?

What did Le Chatelier's principle?

It said if a system of equilibrium is exposed to a stress, the system will shift so as to relieve that stress.

What does the equilibrium always try to do?

It will alway try to have an constant balance.

what is stress in the equilibrium?

Stress is any imposed factor which upsets the balance in rates between the forward and reverse reactions.

What is product?

The elements or compounds produced by a chemical reaction.

What is equilibrium law?

The equilibrium law states that the concentrations of the products multiplied together, divided by the concentration of the reactants multiplied together, equal an equilibrium constant (K). The equilibrium constant is a number which depends on the reaction and the temperature of the reaction mixture when equilibrium is attained.

What is combustion reaction?

The mixing of alkanes (and similar oxygen containing "CH" groups) with molecular oxygen and an activation energy to produce Carbon Dioxide, Water, and large quantities of heat.

This is a synthesis reaction

How to balance a chemical equation?

We change the number of the molecules of how many there is and then find a combination that gives the number of each type of atom on both sides.

What is a double replacement?

What is A type of chemical reaction in which atoms or ions from two different compounds replace each other (AX + BY → AY + BX).

What is Le Chatelier's principle?

When a reaction at equilibrium is changed, it will seek to counteract that change.

How Le Chatelier's Principle can be used to predict the effect of disturbances to equilibrium?

When a reversible reaction is at equilibrium disturbances (in concentration, temperature, pressure, etc.) will be offset to reach a new equilibrium.
