If you burn 23.4 g of hydrogen and produce 209 g of water, how much oxygen reacted?

If a reaction has g of -136kj at 110°c, will it be spontaneous at this temperature (110°c)? yes or no

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 →
