Types of Chemical Equations

Front

What is a coefficient in a chemical equation?

Back

A coefficient is a number placed in front of a chemical formula to indicate how many molecules or moles of that substance are involved in the reaction.

What type of reaction is represented by the equation 3Mg + N2 -> Mg3N2?

Back

Synthesis reaction, where two or more reactants combine to form a single product.

Front

How do you balance the equation __Li + __Cl2 -> __LiCl?

Back

The balanced equation is 2Li + Cl2 -> 2LiCl.

Front

What type of reaction is represented by the equation P4 + 3O2 -> 2P2O3?

Back

Synthesis reaction.

Front

What type of reaction is represented by the equation 3Ca + 2AlCl3 -> 3CaCl2 + 2Al?

Back

Single displacement reaction.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where one reactant breaks down into two or more products.

Front

What is a combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat.

Front

What is a single displacement reaction?

Back

A single displacement reaction is a type of reaction where one element replaces another element in a compound.

Front

What is a double displacement reaction?

Back

A double displacement reaction is a type of reaction where two compounds exchange ions or bonds to form two new compounds.

Front

What does it mean to balance a chemical equation?

Back

Balancing a chemical equation means ensuring that the number of atoms for each element is the same on both sides of the equation.
