Protons would be the top # so 98
Electrons would be the bottom # so 251
Neutrons would be proton and electrons subtracted so 251-98= 153
I hope this is correct and I hope I helped!
Answer:
An oxidizing agent (also called an oxidizer or oxidant) is referred to as a chemical compound that readily transfers oxygen atoms or a substance that gains electrons in a redox chemical reaction.

Answer:
The answer to your question is d. 0.5 M
Explanation:
Data
[A] = 1M
K = 0.5
Concentration of B and C at equilibrium = x
Concentration of A at equilibrium = 1 - x
Equation of equilibrium
k =
Substitution
Simplification
0.5 =
Solve for x
0.5(1 - x) = x²
0.5 - 0.5x = x²
x² + 0.5x - 0.5 = 0
Find the roots x₁ = 0.5 x₂ = -1
There are no negative concentrations so the concentration of A at equilibrium is
[A] = 1 - 0.5
= 0.5 M
MgCl2 =24+2*35.5 = 95 g/mol
Mass MgCl2 = (2.2 mol) (95g/mol) =209 g

That's kind of a ponderous way to describe it, but your 'X' represents
the absolute temperature of the ideal gas.
