Answer:
The coefficient of O2 in the correctly balanced equation is 9
Explanation:
As2S3 + 02 -------------> As2O3 + SO2
Balancing this reaction, we have;
2As2S3 + 9O2 -----------> 2As2O3 + 6SO2
9 moles of oxygen will be the correct coefficient and number of moles for the reaction to be correctly balanced.
In the balanced reaction, we have 4 moles of As; 6 moles of S and 18 moles of O on both sides of the equation.
19.6 × ( 1 mol KOH / 56 grams KOH )
= 0.35 mol KOH
_________________________________
0.35 mol KOH ×( 2 mol H2O / 2 mol KOH )
= 0.35 mol H20
_________________________________
0.35 mol H2O × ( 18 g H2O / 1 mol H2O )
= 6.3 grams H2O
