Balancing Equations and Types of Reaction 2122

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where one compound breaks down into two or more simpler products. Example: H2O2 → H2O + O2.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more reactants combine to form a single product. Example: K + F2 → KF.

Front

What is a combustion reaction?

Back

A combustion reaction is a type of chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat. Example: CH4 + 2O2 → CO2 + 2H2O.

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another in a compound. Example: Zn + CuSO4 → ZnSO4 + Cu.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where the anions and cations of two different compounds switch places, forming two new compounds. Example: AgNO3 + NaCl → AgCl + NaNO3.

Front

What are reactants in a chemical equation?

Back

Reactants are the starting substances in a chemical reaction that undergo change to form products. Example: In Flour + Water + Eggs → Cake, the reactants are Flour, Water, and Eggs.

Front

What are products in a chemical equation?

Back

Products are the substances formed as a result of a chemical reaction. Example: In the equation H2 + O2 → H2O, H2O is the product.

Front

What does a coefficient in a chemical equation represent?

Back

A coefficient indicates the number of molecules or moles of a substance involved in a reaction. Example: In 3H2O, the coefficient '3' means there are three molecules of water.

Front

How do you balance a chemical equation?

Back

To balance a chemical equation, adjust the coefficients of the reactants and products to ensure that the number of atoms for each element is the same on both sides of the equation.

Front

What is the balanced equation for the reaction of nitrogen and hydrogen to form ammonia?

Back

The balanced equation is: N2 + 3H2 → 2NH3.
