Agood hypothesis includes which of the following? a: prediction b: data c: uncertainty d: conclusion

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 →

If anyone would be able to me out with these three questions it would be these are from the chem 2202 course.
