Answer:
Gases are not easily compressible. They float all over and have no arrangement whatsoever. Liquids, however, are closer together, but still have no exact arrangemant. Essentially, gases float all around loosely and liquids would just sit at the bottom of a jar.
Explanation:
Think of a gas filling a room. It is all over and has not order. It only spreads. Now, think of a liquid such as water in a jar. If you only poor a little, it will just sit at the bottom, but when you tilt the glass the water moves. This shows how liquids are compressed, but can still move freely such as gases do.

Answer:
a) 2CH4(g) + S8(s) → 2CS2(l) + 4H2S(g)
b) <u>4.24 moles CS2</u>
<u>c) 8.48 moles H2S</u>
Explanation:
Step 1: The unbalanced equation
CH4(g) + S8(s) → CS2(l) + H2S(g)
(a) Balance the equation. (Use the lowest possible coefficients. Include states-of-matter under the given conditions in your answe.)
2CH4(g) + S8(s) → 2CS2(l) + 4H2S(g)
(b) Calculate the moles CS2 produced when 2.12 mol S8 is used.
For 2 moles CH4 we need 1 mol S8 to produce 2 moles CS2 and 4 moles H2S
For 2.12 moles S8 we'll have 2*2.12 = <u>4.24 moles CS2</u>
(c) How many moles H2S are produced?
For 2 moles CH4 we need 1 mol S8 to produce 2 moles CS2 and 4 moles H2S
For 2.12 moles S8 we'll have 4*2.12 = <u>8.48 moles H2S</u>
