A) nickel + magnesium chloride ?B) calcium + copper(II) bromide ?C) potassium + aluminum nitrate ?D)magnesium + silver nitrate ?Thanks!
Heck Yes, now that I know about it!
i am going to use it to wrap myself in instead of cloths to reflect the sun and keep me cool
hmI don't think I would because I don't want to fill our landfills with extra trash that was unmeaninful.
I have already assembled my armour and have put it in the micro-wave oven for a test run.
A) nickel + magnesium chloride ? Ni + MgCl2(aq) - No reaction Mg is above Ni in activity series B) calcium + copper(II) bromide ? Ca + CuBr2(aq) - CaBr2(aq) + Cu(s) C) potassium + aluminum nitrate ? You might think that it is this reaction 3K + Al(NO3)3(aq) - 3KNO3 + Al(s) But in reality the K would react with the water in which the aluminum nitrate was dissolved and produce KOH(aq) and H2 gasIn the basic solution, Al will react with water to make Al3+ and H2 gasTherefore, no elemental Al will be producedSo the bottom line is that adding K metal to a solution of Al(NO3)3 will leave you with aluminum ions and nitrate ions in solution and potassium ions in solution and hydroxide ions in solution and hydrogen being given off as a gas2K + 2H2O - 2KOH(aq) + H2(g) D) magnesium + silver nitrate Mg + 2AgNO3(aq) - Mg(NO3)2 + 2Ag(s)
