The answer is B Steam rises from the surface of liquid
The ionic equation is simply:
HCN --> H+
+ CN-
Therefore the formula for Ka is:
Ka = [H+] [CN-]
/ [HCN] <span>
[H+] = [CN-] = x
4.9 x 10^-10 = x^2 / 0.023
x^2 = 1.127 x 10^-11
x = 3.357 x 10^-6 = [H+] = [CN-]
pH = -log [H+]
pH = -log 3.357 x 10^-6
<span>pH = 5.47 </span></span>
Answer:
The law of conservation of matter says that matter cannot be created or destroyed. In chemical equations, the number of atoms of each element in the reactants must be the same as the number of atoms of each element in the products
