Explain Milk of Magnesia is a suspension of magnesium hydroxide in water. A common medicine, it is frequently used as an antacid for the reason that it neutralizes hydrochloric acid in the stomach
Mg(OH)2(s) + 2 HCl(aq) ? Mg2+(aq) + 2 H2O(l)
Compute the mass of HCl that is neutralized by 0.9 g of Mg(OH)2(s).
The following mechanism has been proposed for the gas-phase reaction of chloroform (CHCl3) and chlorine: 1) Cl2 ? 2 Cl (fast, reversible) 2) Cl + CHCl3 ? HCl + CCl3 (slow) 3) Cl + CCl3 ? CCl4 (fast) What rate law does this mechanism predict
