Answer:
when an atom, typically a metal, loses an electron or electrons, and becomes a positive ion, or cation. Another atom, typically a non-metal, is able to acquire the electron(s) to become a negative ion, or anion.
Explanation:
Pressures oxygen and hydrogen + pressure nitrogen
110 Kpa + 106 Kpa = 216 Kpa
Partial pressure:
total pressure - exerted by nitrogen:
282 Kpa - 216 Kpa
= 66 Kpa
hope this helps!

What Is
at 400 K for the following reaction?

(A) 8.2 x 10⁻⁴
(B) 2.9 x 10⁻²
(C) 6.7 x 10⁻⁷
(D) 1.6 x 10⁻⁷
Answer : The correct option is, (C) 
Explanation :
The given chemical equation follows:

The equilibrium constant for the above equation,
.
We need to calculate the equilibrium constant for the following equation of above chemical equation, which is:
, 
The equilibrium constant for the doubled reaction will be the square of the initial reaction.
Or, we can say that
If the equation is multiplied by a factor of '2', the equilibrium constant will be the square of the equilibrium constant of initial reaction.
The value of equilibrium constant for the following reaction is:



Hence, the value of equilibrium constant for the following reaction is,
