O
Explanation:
Oxygen is a more reactive non-metal.
There are several parameters to test how reactive an element is. In this case, we are going to use the electronegativity of the two atoms.
- Electronegativity is the relative tendency with which atoms of the element attract valence electrons in a chemical bond.
A high electronegativity value suggests more reactivity and a low value implies low reactivity.
On the Pauling's Eelectronegativity table, Oxygen has a value of 3.5 and Phosphorus has 2.1
It implies that oxygen is a more reactive non-metal compared to phosphorus.

Carbon can go either way they can have a 4+ charge (by losing 4 electrons) or a 4- charge (by gaining 4 electrons) to fulfill the octet rule.
The mass of the aqueous solution in grams is obtained by subtracting mass of the 10.0 mL graduated cylinder alone from the mass of the cylinder + solution. Therefore mass of the solution is 2.951 g.
We have from the question, the following information;
Mass of empty 10.0 mL graduated cylinder to be 23.099 g
Mass of 10.0 mL graduated cylinder + 3.09 mL of solution to be 26.050g
Mass of aqueous solution in grams = mass of the cylinder + solution - mass of the 10.0 mL graduated cylinder alone
= 26.050g - 23.099 g
= 2.951 g
