10. MGRC4 When cobalt(II) nitrate solution is mixed with sodium phosphate, a precipitate forms,
a) Write the equation for the reaction and balance it. Hint: There are two products!!
b) How many moles sodium phosphate would be required to react with 0.650 moles of cobalt (II) nitrate? (Must
show all work!
c) How many grams of solid product would be produced if you ran the reaction using 0.650 moles of cobalt(II)
nitrate and the the number of moles of sodium phosphate that you calculated in b)? The molar mass of the nitrate
ion is 62.0 g/mol and of the phosphate ion is 95.0 g/mol
11. LR2 Magnesium metal reacts with chlorine gas to form magnesium chloride. Write and balance the chemical
equation. Then draw and label 3 boxes. Inside the boxes, draw a particle-based representation of 2 moles of
magnesium and 2 moles of chlorine reacting to form the product. Is there a limiting reactant? If so, which one is
it?
