Chemical Reactions

Front

What is a coefficient in a chemical equation?

Back

A coefficient is a number in front of a chemical formula that indicates how many molecules or atoms of each reactant and product are involved in a reaction.

Front

What type of chemical reaction occurs when two or more substances combine to form a new compound?

Back

Synthesis reaction.

Front

What type of chemical reaction is represented by the equation: Ca + MgCl2 → CaCl2 + Mg?

Back

Single Replacement reaction.

Front

What is a double replacement reaction?

Back

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

Front

What type of chemical reaction is represented by the equation: Al(OH)3 → Al2O3 + H2O?

Back

Decomposition reaction.

Front

What is the general form of a synthesis reaction?

Back

A + B → AB, where A and B are reactants that combine to form a single product AB.

Front

In a single replacement reaction, what happens to the elements involved?

Back

One element replaces another element in a compound.

Front

What is the general form of a double replacement reaction?

Back

AB + CD → AD + CB, where two compounds exchange components.

Front

What is the difference between a synthesis reaction and a decomposition reaction?

Back

A synthesis reaction combines reactants to form a single product, while a decomposition reaction breaks down a compound into simpler products.

Front

What is an example of a decomposition reaction?

Back

The breakdown of water (H2O) into hydrogen (H2) and oxygen (O2) gases.
