Question

Please help me with this chemistry problem

Answer 1

below

Step-by-step explanation:

Zn mole wt =65.38 145 / 65.38 =2.2 moles

S mole wt = 32 36/32 = 1.1 mole

From the balanced equation you need 8 moles of Zn for each mole of S

so you are very short of Zn <=====limiting reactant

there is a 1:1 ratio of the moles of Zn to ZnS produced....so you will get 2.2 moles of ZnS (but you will only use .275 mole of the sulfur)
