How many atoms of each element are in the chemical formula p2o5?

2 phosphorus and 5 oxygen
5 phosphorus and 2 oxygen
1 phosphorus and 5 oxygen
2 phosphorus and 1 oxygen

Option a 2 phosphorus and 5 oxygen

Explanation:

Phosphorous pentoxide is having molecular formula as

P4O10 and is a chemical compound.  The empirical formula for Phosphorous pentoxide is P2O5

This contains 2 phosporous and 5 oxygen

Normally in a chemical formula the suffix after the symbol stands for the number of atoms in the compound

Here P has suffix 2 and hence there are 2 phosporus atoms and

O has suffix 5, hence Oxygen atoms are 5.

Option A is right

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.
