17) Answer each of the following: [I point each or 5 points total] a) The name of the gas released when an acid acts upon a carbonate-containing material: b) The name of the gas released when an acid acts upon an active metal like calcium:- c) The name of a chemical system that will control the level of acidity: d) The name of the gas released when an acid acts upon a sulfide-containing material: e) The name of the gas released when an acid acts upon a sulfite-containing material: How many kilograms of table salt must be added to 10.00 kg of water to produce pickling brine that is 18) 20% by weight of salt? To solve this, rearrange the following equation: (4 points) Pct. by wt.- *100% mass of solute) (mass of solute) +(mass of solvent) /21

Explanation / Answer

(a) Carbon dioxide

(b) hydrogen

(c) buffer

(d) hydrogen sulfide

(e) sulfer doxide

18.

Suppose x kilograms of table salt is to be added to 10.00 kg of water (solvent)

The resultant solution has 20% by weight of the salt

20 = (x/ 10+x) *100

Solviing it, we get:

0.2 * (10+x) = x

x = 2.5

Answer is: 2.5 kg
