FA24 OL Balancing Chemical Equations and Types of Reactions

Front

What must be true about the number of atoms in a chemical reaction?

Back

The number of atoms you begin with in a chemical reaction must be the same as the number of atoms you end with.

Front

How do you balance the equation: ____ Fe + ____ Cl2 → ____ FeCl3?

Back

The balanced equation is 2 Fe + 3 Cl2 → 2 FeCl3.

Front

What is a chemical reaction?

Back

A chemical reaction is a process in which atoms rearrange to form new substances.

Front

What is produced when hydrogen reacts with sulfur?

Back

When hydrogen reacts with sulfur, dihydrogen monosulfide (H2S) is produced.

Front

How do you balance the equation: ____ Al + ____ HCl → ____ AlCl3 + ____ H2?

Back

The balanced equation is 2 Al + 6 HCl → 2 AlCl3 + 3 H2.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction.

Front

What is the purpose of balancing chemical equations?

Back

The purpose of balancing chemical equations is to ensure that the same number of each type of atom appears on both sides of the equation.

Front

What are the types of chemical reactions?

Back

The main types of chemical reactions include synthesis, decomposition, single replacement, double replacement, and combustion.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction in which two or more reactants combine to form a single product.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction in which a single compound breaks down into two or more simpler products.
