Question

2. Classify each of the following reactions as a

synthesis, decomposition, single-displacement,
double-displacement, or combustion reaction:
a. N.(g) + 3H2(g) +2NH2(g)
b. 2Li(s) + 2H,0(1) -2LIOH(aq) + H2(g)
C. 2NaNO3(s) +2NaNO3(s) + 0,(9)
d. 2CH() + 190,(g) 1200,(g) + 14H,O(1)​

Answer 1

a. Synthesis reaction

b. Single - Displacement

c. Decomposition reaction

d. Combustion Reaction

Step-by-step explanation:

`N_(2) + 3H_(2)\rightarrow 2NH_(3)`

Synthesis reaction: Reaction in which two or more substance combine to give a single compound.

`Li + H_(2)O\rightarrow LiOH +H_(2)`

Single - Displacement : Reaction in which the more reactive element displaces the less reactive element.Here Li replace OH from water.

`NaNO_(3)\rightarrow NaNO_(2)+ O_(2)`

Decomposition reaction: Reaction in which a single reactant decompose to give two or more products.

`CH_(4) + O_(2)\rightarrow CO_(2)+H_(2)O`

Combustion Reaction : IT is a redox reaction in which a substance is burned in the presence of oxygen to give carbon dioxide and water.
