Question

29. Ammonium Perchlorate is used as solid fuel in
rockets. During the process * decomposes
according to the reaction given below
4NH4ClO4=8H2O + 2N2O +3O2
The total volume of all the gases produced at
S.T.P by the decomposition of 6 moles of
Ammonium Perchlorate will be
a. 30L
b. 672L
c. 179.2 L
d. 313.6L

Answer 1

Answer:

d

Explanation:

4 moles give 7 moles of gas (2 Cl2, 2N2O and 3 O2)

8 moles will give 14 moles

at stp 1mole of gas has 22.4l volume

14 moles would have 14×22.4l = 313.6 ltr
