Question

Identify the correct combination reaction of two compounds to form a new product

A
H2+Cl22HCl
B
2CO+O22CO2
C
CaO+H2OCa(OH)2
D
NH3+HClNH4Cl

Solution

The correct options are A $$H_{2} + Cl_{2} \rightarrow 2HCl$$ B $$CaO + H_{2}O \rightarrow Ca(OH)_{2}$$ C $$2CO + O_{2}\rightarrow 2CO_{2}$$ D $$NH_{3} + HCl \rightarrow NH_{4}Cl$$A combination reaction is a reaction where two or more elements or compounds combine to form a single compound (product). Such reactions may be represented by equations of the following form: X + Y $$\longrightarrow$$ XY.Example -  $$CaO + H_{2}O \longrightarrow Ca(OH)_{2}$$                  $$NH_{3} + HCl \longrightarrow NH_{4}Cl$$So all of the above options are correct.Chemistry
