Answer:
Volume is 10.35 L
Explanation:
we are given;
- Initial volume v₁ is 10 L
- Initial pressure, P₁ as 745 mmHg
- New pressure ,P₂ as 720 mmHg
We are required to determine the new volume, V₂
We are going to use the Boyle's law;
According to Boyle's law the volume and the pressure of a fixed mass of a gas are inversely proportional at a constant temperature.
Therefore;
P₁α 1/V
That is;
P = k/V
k = PV
At different conditions;
P₁V₁ = P₂V₂
Rearranging the formula;
V₂ = P₁V₁ ÷ P₂
Thus;
New volume = (10 L× 745 mmHg) ÷ 720 mmHg
= 10.35 L
Thus, the new volume of the gas at the new pressure is 10.35 L
The element itself is Yttrium, which is a transition metal and not that reactive. Since it has 39 protons it will also have 39 electrons.

Explanation:
According to the law of conservation of mass; the total mass of reactants on the left hand side of the reaction equation is equal to the total mass of products on the right hand side of the reaction equation.
Hence, the total mass of each atom on either side of the reaction equation should be exactly the same.
Since there are two atoms of oxygen on the reactants side, the total mass of oxygen = 16 amu * 2 = 32 amu
Since there are two oxygen atoms on the products side, total mass of oxygen = 16 amu * 2 = 32 amu
