Question

Ammonium perchlorate NH4ClO4 is the solid rocket fuel used by the U.S. Space Shuttle. It reacts with itself to produce nitrogen gas N2, chlorine gas Cl2, oxygen gas O2, water H2O, and a great deal of energy. What mass of chlorine gas is produced by the reaction of 3.3g of ammonium perchlorate? Be sure your answer has the correct number of significant digits.

Answer 1

To calculate the mass of chlorine gas produced from 3.3g of ammonium perchlorate, stoichiometry is needed along with the balanced chemical equation, molar masses, and mole ratios. However, without the balanced equation, the calculation cannot be completed.

Step-by-step explanation:

To determine the mass of chlorine gas produced by the reaction of 3.3g of ammonium perchlorate, NH4ClO4, we will need to use stoichiometry. The balanced chemical equation for the decomposition of ammonium perchlorate is not provided, but we can assume it yields nitrogen gas, N2, water, H2O, oxygen gas, O2, chlorine gas, Cl2, and energy. Since this is a problem related to stoichiometry, we'll also need the molar mass of NH4ClO4 and Cl2 to proceed, as well as the mole ratio of NH4ClO4 to Cl2 from the balanced equation. However, with the information provided, we cannot complete the calculation. It's important to note that the answer should contain the same number of significant figures as the given mass of ammonium perchlorate (3.3g), which is two significant figures.

Answer 2

Answer: 0.99 grams of chlorine gas is produced by the reaction of 3.3g of ammonium perchlorate

Step-by-step explanation:

To calculate the moles, we use the equation:

`\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}`

`\text{Number of moles of } NH_4ClO_4=(3.3g)/(117.5g/mol)=0.028moles`

The decomposition of ammonium perchlorate is :

`2NH_4ClO_4\rightarrow Cl_2+N_2+2O_2+4H_2O`

According to stoichiometry :

2 moles of
`NH_4ClO_4` produce = 1 mole of
`Cl_2`

Thus 0.028 moles of
`NH_4ClO_4` produce=
`(1)/(2)* 0.028=0.014moles` of
`Cl_2`

Mass of
`Cl_2=moles* {\text {Molar mass}}=0.014moles* 71g/mol=0.99g`

Thus 0.99 grams of chlorine gas is produced by the reaction of 3.3g of ammonium perchlorate
