Question

What kind of reaction is this ? P+02-P4010
A.Synthesis
B. Decomposition
C.Single Replacement
D. Double Replacement

Answer 1

Answer:

A.Synthesis

Explanation:

Let's consider the following unbalanced reaction.

P + O₂ ⇒ P₄O₁₀

To get the balanced equation, so that the equation follows the law of conservation of matter, we will need to multiply P by 4 and O₂ by 5.

4 P + 5 O₂ ⇒ P₄O₁₀

This kind of reaction is known as a synthesis reaction, in which 2 simple substances combine to form a compound (P₄O₁₀).
