Question

Identify the single displacement reaction. 2H 2 + O 2 ⟶ 2H 2O Al 2S 3 ⟶ 2Al + 3S Cl 2 + 2KBr ⟶ 2KCl + Br 2 C 4H 12 + 7O 2 ⟶ 6H 2O + 4CO 2

Answer 1

D.

Step-by-step explanation:

Answer 2

Answer:
`Cl_2+2KBr\rightarrow 2KCl+Br_2`

Step-by-step explanation:

A single displacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution. Thus one element should be different from another element.

`Cl_2+2KBr\rightarrow 2KCl+Br_2`

Synthesis reaction is defined as the reaction where substances combine in their elemental state to form a single compound.
`2H_2+O_2\rightarrow 2H_2O`

Decomposition reaction is defined as the reaction where a single substance breaks down into two or more simpler substances.

`Al_2S_3\rightarrow 2Al+3S`

Combustion is a type of chemical reaction in which hydrocarbons burn in the presence of oxygen to form carbon dioxide and water along with heat.

`C_4H_(12)+7O_2\rightarrow 6H_2O+4CO_2`
