Calculate the molar mass of magnesium chloride, CaCl 2.

Ca = 40.1g, Cl = 35.5g

10. according to the law of conservation of mass, how does the mass of the products in a chemical reaction compare to the mass of the reactants?

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 →

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.
