Question

What is the final chemical equation from the following intermediate chemical equations?

P4​O6​(s)→P4​(s)+3O2​(g)
P4​(s)+5O2​(g)→P4​O10​(s)
P4​O6​(S)+2O2​(g)→P4​O10​(s)+O
P4​O8​(s)+8O2​(g)→2P4​(s)+P4​O10​(s)+O
P4​O6​(S)+15O2​(g)→P4​(s)+P4​O10​(s)+H2​O

a. P4(s)+6O2(g)→P4O10(s)
b. P4O8(s)+8O2(g)→2P4(s)+P4O10(s)+O
c. P4O6(S)+15O2(g)→P4(s)+P4O10(s)+H2O
d. P4O6(S)+2O2(g)→P4O10(s)+O

Answer 1

The final chemical equation is (a) P4 (s) + 6O2 (g) → P4O10 (s), a balanced synthesis reaction that conserves the mass and number of atoms.

Step-by-step explanation:

The question is asking for the final chemical equation from a list of intermediate chemical equations involving phosphorus and oxygen compounds. Looking at the options provided, we want to identify a balanced chemical reaction that results from these intermediates.

The correct answer is (a) P4 (s) + 6O2 (g) → P4O10 (s), which represents a balanced synthesis reaction. This is a combination of the first two equations given: P4O6 is being oxidized to P4O10 by adding more oxygen, and P4 reacts with oxygen to form P4O10 directly. There is conservation of mass and the same number of atoms on both sides of the equation, which is a fundamental principle in chemistry.
