4K(s) + O2(g) → 2 K2O(s). If a staff member at a laboratory has 12.0 grams of potassium metal, what is the theoretical yield of potassium oxide that the scientist could potentially produce from the reaction with oxygen gas?

100mg magnesium reacts with 20ml of 1.0m hcl

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 →

In a reaction (at equilibrium) that makes more moles of gas than it consumes, what is the effect of increasing the pressure?
