9. Ammonium chloride reacts with calcium hydroxide as shown in the following
equation
2NH Cl(aq) + 2 Ca(OH),(aq) →
2NH,(g) + CaCl,(aq) + 2H, O(1)
Calculate the mass of ammonium chloride
(NH CI) that will react completely with
14.8 g of calcium hydroxide.​

To prevent the presence of air, noble gases are placed over highly reactive chemicals to act as inert "blanketing" gases. a chemical engineer places a mixture of noble gases consisting of 4.37 g of he, 13.36 g of ne, and 36.65 g of kr in a piston-cylinder assembly at stp. calculate the partial pressure in torr of kr.
