Two students were working with 3 beakers that look the same. Unfortunately the labels got mixed up and so now they are trying to decide which beaker is which. One is an ionic compound dissolved in water. One is a polar covalent compound dissolved in water. One is a nonpolar substance.

Which answer lists the fundamental forces in order from strongest to weakest

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 →
