Question

STOICHIOMETRY

Answer 1

Answer:

Explanation:

Br₂(g)   +    Cl₂(g)     =>   2BrCl(g)

excess   2.74mole        ?moles

Rxn ratio is 1mole Cl₂(g) : 2mole BrCl  which means the yield of BrCl must be larger mole value than the Cl₂(g) mole value. This is accomplished by multiplying the given moles Cl₂(g) by a ratio of coefficients that will make the results larger.

moles BrCl(g) produced = 2/1(2.47mole BrCl(g) = 5.48 mole BrCl(g)
