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

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).

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
