grigory [225]

Answer: 0.45 moles of H_2O will be produced from 0.15 moles of propanol.

Explanation:

The balanced chemical reaction is:

2C_3H_6O+8O_2\rightarrow 6CO_2+6H_2O

C_3H_6O is the limiting reagent as it limits the formation of product and O_2 is the excess reagent.

According to stoichiometry :

2 moles of C_3H_6Oproduces = 6 moles of H_2O

Thus 0.15 moles of V will produce=\frac{6}{2}\times 0.15=0.45moles  of H_2O

Thus 0.45 moles of H_2O will be produced from 0.15 moles of propanol.

mixer [17]

Answer:

A)

Cl + O3 --> ClO + O2

2ClO --> ClOOCl

ClOOCl --> 2 Cl + O2

B)

Cl2 + 4O3 -> 2 ClO + 5O2

Explanation:

Step 1: Chlorine atoms react with ozone (O3) to form chlorine monoxide and molecular oxygen

Cl + O3 --> ClO + O2

Step 2: Chlorine monoxide molecules combine to form ClOOCl gas

2ClO --> ClOOCl

Step 3: ClOOCl absorbs sunlight and breaks into chlorine atoms and molecular oxygen

ClOOCl --> 2 Cl + O2

B) Overall Balanced equation

Cl2 + 4O3 -> 2 ClO + 5O2
