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.

We calculate the molar concentration [Cl⁻] using stoichiometry. MnCl2(aq) is an ionic compound which will have the releasing of 2 Cl⁻ ions ions in water for every molecule of MnCl2 that dissolves.
MnCl2(s) --> Mn+(aq) + 2 Cl⁻(aq)
[Cl⁻] = 0.68 mol MnCl2/1L × 2 mol Cl⁻ / 1 mol MnCl2 = 1.4 M
The answer to this question is [Cl⁻] = 1.4 M
Answer: 9.75 x10^23
Explanation: you do 6.02x10^23 times 1.62. And then round to three digits.
Natural gas is nonrenewable, once its used you have to get more, after its all used up you cant use it no more.
