No. Of protons = mass no. - no. Of neutrons
No. Of protons = 67 - 37
= 30
No. Of electrons = 28
Zinc will have 30 protons and 28 electrons. So, it will have +2 charge
Symbol - Zn^+2

[C] carbon solid
Explanation:
Pure solids and liquids are never included in the equilibrium constant expression because they do not affect the reactant amount at equilibrium in the reaction, thus since your equation has [C] as solid it will not be part of the equlibrium equation.
Answer:
10
Explanation:
Given endpoints:
E (-2,2) and F(4, -6)
To find the distance between two points;
Use the expression below;
D = 
x₁ = -2,
x₂ = 4
y₁ = 2
y₂ = -6
Insert the parameters and solve;
D = 
D = 
= 10
