HCL(g) it consists of covalently molecules which are bonded and they do not ionize.
Non-polar solvent molecules do not attract molecules of HCL which cause them to be ionized.

Answer:
aa. Which sample(s) is classified as a compound? How do you know?
C. The buoyant force must be greater to float, otherwise it would sink, its like a barrel in water, the more water weight in it the more it sinks, the more air weight the more it rises.
Answer: see below
<u>Explanation:</u>
When multiplying or dividing, use the smallest number of significant figures (sf) of the digits provided.
37(a) 24 × 3.26 = 78.24 <em>2 sf × 3 sf </em>--> round to 2 sf's
≈ 78
(b) 120 × 0.10 = 12 <em>2 sf × 2 sf </em>--> round to 2 sf's
= 12
(c) 1.23 × 2.0 = 2.46 <em>3 sf × 2 sf </em>--> round to 2 sf's
= 2.5
(d) 53 × 1.53 = 81.09 <em>2 sf × 3 sf </em>--> round to 2 sf's
= 81
38(a) 4.84 ÷ 2.4 = 2.0167 <em>3 sf × 2 sf </em>--> round to 2 sf's
= 2.0
(b) 60.2 ÷ 20.1 = 2.995 <em>3 sf × 3 sf </em>--> round to 3 sf's
= 3.00
(c) 102.4 ÷ 51.2 = 2 <em>4 sf × 3 sf </em>--> round to 3 sf's
= 2.00
(d) 168 ÷ 58 = 2.896 <em>3 sf × 2 sf </em>--> round to 2 sf's
= 2.9
