Determine the products 2. Balance the equation 3. Determine the physical states using the
solubility rules ZnSO, + MgCl, Consider the following reaction a. How many moles of O, are
needed to react with 4.2 mol NH,? b. How many moles of H,O can be produced from 1.34 mol
0.? c. How many grams of NH, will react with 43.4 g 0? d. How many grams of O, are needed to
produce 56 g NO? Determine the oxidation values for the elements in the following compounds
a. CrO Cr b, H c. H,SO, H d. POP e. C6H1206 C f. KNO, 0 0
Solution
Ans 1 :
1) The products of the reaction will be : ZnCl2 and MgSO4
2) The balanced reaction is given as :
ZnSO4 + MgCl2 = ZnCl2 + MgSO4
3) Since both the sulfates and chlorides of zinc and magnesium are soluble in water according to
the solubility rules , so the physical states of all the species will be aqueous.
