Types of Chemical Reactions

Question 1

What are the Types of Chemical Reactions?

Answer 1

Synthesis (combination), Decomposition, Replacement (single or double), and Combustion.

Question 2

What are the Symbols for Chemical Reactions?

Answer 2

(s) - solid reactant or product.
(l) - liquid reactant or product.
(g) - gaseous reactant or product.
(aq) - reactant or product in water.

Question 3

What is the Formula for Synthesis Reactions?

Answer 3

A + B -> AB. Two reactants and one product.

Question 4

What is the Formula for Decomposition Reactions?

Answer 4

XY - > X + Y. One reactant and two (or more) products.

Question 5

What is the Formula for Single Replacement Reactions?

Answer 5

X + YZ -> XZ + Y.

Question 6

What is the Formula for Double Replacement Reactions?

Answer 6

AB + XY -> AY + XB.

Question 7

What is the Formula for Combustion Reactions?

Answer 7

A + O2 -> CO2 + H2O. Reaction occurs in presence of oxygen, combustion reactions can also be synthesis reactions.

Question 8
