<span>(8.5 x 10^-3 mol) / (0.0320 mol/L KCN)=0.265625 L=265.625 ml.
This is the volume of a 0.0320 M KCN solution that would give a median lethal dose to a 185 lb person.</span>
Answer:
Kc = 0.0122
Explanation:
For a given equilibrium reaction, the equilibrium constant is calculated by taking the ratio between the equilibrium concentrations of the products and the equilibrium concentrations of the reactants, each raised to the power of their respective stoichiometric coefficients.
The answer is acidic.
pH < 7 = acidic
pH > 7 base
Materials with ionic bonds tend to be more easily scratched.
