combination reaction.

decomposition reaction.

displacement reaction

double displacement reaction

redox reaction

Answer 2

Answer:

chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products.

Explanation:

Types of chemical reaction-

• Combination Reactions

A combination reaction, also known as a synthesis reaction, is a reaction in which two or more substances combine to form a single new substance. .The general form of a combination reaction is:

2Ca + O2 → 2CaO

• Decomposition Reactions

A decomposition reaction is a reaction in which a compound breaks down into two or more simpler substances. The general form of a decomposition reaction is:

2HgO(s)→2Hg(l)+O2(g)(5.3.5)(g)→2NaCl(s)

• Single-Replacement Reactions

A single-replacement reaction is a reaction in which one element replaces a similar element in a compound. The general form of a single-replacement (also called single-displacement) reaction is:

Mg(s)+Cu(NO3)2(aq)→Mg(NO3)2(aq)+Cu(s)

• Double-Replacement Reactions

A double-replacement reaction is a reaction in which the positive and negative ions of two ionic compounds exchange places to form two new compounds. The general form of a double-replacement (also called double-displacement) reaction is:

2KI(aq)+Pb(NO3)2(aq)→2KNO3(aq)+PbI2(s)

• Combustion Reactions

A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat. Combustion reactions must involve  O2  as one reactant. The combustion of hydrogen gas produces water vapor (see figure below).

2H2(g)+O2(g)+2H2O(g)
