The balanced reaction is:
Ga(l) + As(s) → GaAs(s)
From the reaction:
You may want to reference (Pages 106 - 109)Section 3.7 while completing this problem.
Molten gallium reacts with arsenic to form the semiconductor, gallium arsenide, GaAs, used in light emitting diodes and solar cells:
Ga(l) + As(s) GaAs(s)
If 4.00 g of gallium is reacted with 5.50 g of arsenic how many grams of the excess reactant are left at the end of the reaction?
