10.00 g of hydrochloric acid reacts with excess calcium to form hydrogen gas and calcium chloride. What mass of calcium chloride will be formed?
2HCl + Ca → H2 + CaCl2
+36916 Using periodic table of elements
usually 72.916 gm of HCl reacts and forms 75.528 gm of CaCl
we can set up a ratio
10/72.916 = x / 75.528 x = CaCl formed = 10.358 gm
