Answer:
the gas particles strike the walls of the container more often
Explanation:
Following Boyle's law, if the amount of gas and the temperature remain constant, the product of the pressure for the volume remains constant, but when altering any of these conditions this value changes and is expressed through the equation:
<em> </em>
<em></em>
So, when the volume decreases, the distance that the particles have to travel is smaller and therefore more collisions between particles and between the walls occur per unit of time, that is, the system pressure increases.
I’m just letting you know this is really easy you just calculate the molar mass of each compound and divide the amount of the compound (grams) by the molecular Mass
You didn’t give us the options???
anyways: Water diffusion is called osmosis. Oxygen is a small molecule and it's nonpolar, so it easily passes through a cell membrane. Carbon dioxide, the byproduct of cell respiration, is small enough to readily diffuse out of a cell. Small uncharged lipid molecules can pass through the lipid innards of the membrane.

Explanation:</h3>
<u>Step 1: Define</u>
[RxN - Balanced] Fe₃O₄ + 4H₂ → 3Fe + 4H₂O
[Given] 705.0 g H₂O
<u>Step 2: Identify Conversions</u>
[RxN] 4 mol H₂O → 1 mol Fe₃O₄
Molar Mass of H - 1.01 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of Fe - 55.85 g/mol
Molar Mass of H₂O - 2(1.01) + 16.00 = 18.02 g/mol
Molar Mass of Fe₃O₄ - 3(55.85) + 4(16.00) = 231.55 g/mol
<u>Step 3: Convert</u>
