Answer:
2.475 mol of O2 formed.
Explanation:
Given 1.65 moles of KClO3 as the target amount in the reactant, used the coefficient of the balanced chemical reaction involved to determine the number of moles of O2 molecules formed.
x mole of O2 = 1.65 mol KClO3 x [(3 mol O2)/ (2 mol KClO3)] = 2.475 mol of O2
x mole of O2 formed = 2.475 mol of O2
Answer:
34.32 oz
Explanation:
1.- The carpet has the dimension 12 x 11 ft, so it has an area = 12 x 11 = 132 ft2
To convert the Ft2 into yd2:
9 ft2 = 1 yd2
132 ft2 = x X = (132 x1) / 9 = 14.6 yd2
2.- By now, it is now that the 39 % is burned, so obtain the 39 % of 14.6 yd2
14.6 yd2 = 100 %
x = 39 % x = (39 x 14.6) / 100 = 5.72 yd2
3.- It is known that 30 oz acrylan /yd2
30 oz = 1 yd2
x = 5.72 yd2 X = (5.72 x 30) /1 = 171.6 oz
4.- It is assume that just the 20 % of the fibers has HCN
171.6 oz = 100 %
x = 20 % X = (20 x 171.6) /100 = 34.32 oz
