What are the correct coefficients for the unbalanced equation below? P4 +02 → P2O5

A)1,1,1
B) 1,3,1
C)1,5, 2
D)2,1,2
E)none of the above

PLEASE EXPLAIN WHY! I will mark the brainliest!

C; 1, 5, 2

Explanation:

First, we do atom inventory:

Think of the arrow as a divider

On the left side, we have 4 phosphorus and 2 oxygens

On the right side, we have 2 phosphorus and 5 oxygens

Now we try to balance:

To make it easier, we want to try and make the 5 oxygens get to an even number so, we put a 2 in front of the P2O5 which makes it 2P2O5

Since we put a 2 in front of the P2O5, we have to multiply our phosphorus and oxygen on the right side by 2, which brings us to now have 4 phosphorus and 10 oxygens.

So now the oxygens are unbalanced.

To balance the oxygens, we put a 2 in front of the O2 located on the left side which makes us multiply our oxygen by 5, making it now 10.

Final result:

We end up having P4 + 5O2 = 2P2O5

(1, 5, 2)

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

if you're asking what comes out, it's steam.
