Question

A synthesis reaction is a reaction between at least two compounds in which

a. one breaks down into at least two products.
b. a compound is decomposed by an electric current.
c. a compound burns in the presence of oxygen.
d. a new compound is formed.

Answer 1

D; a new compound is formed (like A + B --> AB)

Answer 2

Answer: d. a new compound is formed.

Step-by-step explanation:

1. Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.

Example:
`Li_2CO_3\rightarrow Li_2O+CO_2`

2. Electrolytic decomposition is a type of chemical reaction in which one reactant gives two or more than two products. on passing electric current.

Example:
`H_2O\rightarrow H_2+(1)/(2)O_2`

3. Combustion is a type of chemical reaction in which fuel is reacted with oxygen to form carbon dioxide and water.

Example:

`C_6H_(12)O_6+O_2 \rightarrow CO_2+H_2O`

4. Synthesis reaction is a chemical reaction in which two reactants are combining to form one product.

Example:
`Li_2O+CO_2\rightarrow Li_2CO_3`
