A 0.515 g sample of CaCl2 reacts with aqueous sodium phosphate to give 0.484 g Ca3(PO4)2. Show the calculation for the theoretical yield of Ca3(PO4)2. What is the percent yield of Ca3(PO4)2.

If the particles in a sample of matter have an orderly arrangement and move only in place, the sample is a

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 →
