Answer:
1.125 moles of H2S
Explanation:
From 2HCl(aq) + ZnS(s) ---------> H2S (g) + ZnCl2 (aq)
From the reaction equation;
2 moles of HCl produces 1 mole of H2S
Therefore 2.25 moles of HCl will produce 2.25 ×1/2 = 1.125 moles of H2S
Recall that it was explicitly stated in the question that ZnS is the reactant in excess. This implies that HCl is the limiting reactant and controls the amount of product obtained.
Not a stable electron configuration
Product:
C: 1
O:3
H: 2
reactant:
C: 8
H: 18
O: 2
first you need to put probably an eight in front of the Carbon.
Next, add a coefficient of 9 to Hydrogen
finally, add a 3 INSTEAD of a 2 to Oxygen
should look like:
C8H18+O3>C8O2+H9O
