A solution of sulfuric acid with a concentration of 2.0M reacts with a metal. Will a solution of sulfuric acid with a concentration of 1.0M and the same metal, have a HIGHER or LOWER rate of reaction? Explain why:

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 →
