The volume of a gas if it is compressed.
increases
stays the same
decreases
Help me please

1. combine iron and copper (ii) sulfate solution. (hint: iron will form the iron (iii) ion) fe + cuso4 → 2. combine lead (ii) nitrate and potassium iodide solutions. pb(no3)2+ kl → 3. combine magnesium metal and hydrochloric acid solution. mg + hcl → 4. electrolysis (splitting) of water. h2o → 5. burning magnesium. mg + o2 →

At 300 mm hg, a gas has a volume of 380 l, what is the volume at standard pressure

Suppose you wanted to make 100 grams of water. what is the molar mass of water (h2o)?
