Answer the following questions showing all appropriate work on the back or separate sheet of paper
1)How many grams of sodium phosphide do I react to react to obtain 45.3g of calcium phosphide using chemical equation below (balance first)
___ Ca1Br2 + ____ Na3P1 ==> ____ Ca3P2 + ____ Na1Br1
2)How many liters of oxygen @ STP do I get if I react 234g of the reactant from the equation below (balance first):
___ Li3P1O4 ==> ____ Li + ____P + ____ O2
3)How many gallons of C8H18 (called octane, the main ingredient in gasoline) do I need to react to get 5.45E3 liters of C1O2 (a gas @STP) from equation below (first balance). Octane is not a gas but a liquid so need density, D = 0.875g/ml).
___ C8H18 + ____ O2 ==> ____ C1O2 + ____ H2O1
