Synthesis reaction

Explanation:

To know which option is correct, it important that we know what each option represents.

Synthesis reaction is a reaction in which two different elements react to form a single compound. For example

X + Y —> XY

Decomposition reaction is a reaction in which a compound splits into two or more simpler substance. For example

XY —> X + Y

Single Replacement reaction is a reaction in which one element replaces or displaces another element from a compound. For example

X + YZ —> XZ + Y

Double Replacement reaction is a reaction in which the parts of two ionic compounds exchange their ions to form a new compound. For example

WX + YZ —> WZ + YX

Now, considering the equation given above i.e

P + O₂ —> P₄O₁₀

We can see that P and O₂ reacted to produce a new compound (i.e P₄O₁₀).

Thus, the reaction is a synthesis reaction because two different elements (i.e P and O₂) reacted to form a single compound (i.e P₄O₁₀).

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.

did anyone actually do this? like if anyone has submitted this i rly need .
