Answer from: shygrl05

67.2 moles

Explanation: $2C_2H5+5O_2\rightarrow 4CO_2+2H_2O$

According to the given balanced equation, 2 moles of acetylene C_2H_2 combine with 5 moles of oxygen O_2 to produce 4 moles of carbon dioxide CO_2 .

Thus if 2 moles of acetylene C_2H_2 combine with = 5 moles of oxygen O_2

35 moles of acetylene C_2H_2 combine with= $\frac{5}{2}\times {35}=87.5$ moles of oxygen O_2

But as only 84 moles of oxygen are available, acetylene is not a limiting reagent.

5 moles of oxygen O_2 reacts with = 2 moles of acetylene C_2H_2

84 moles of oxygen O_2 reacts with= $\frac{2}{5}\times {84}=33.6$ moles of acetylene C_2H_2

Thus Oxygen is the limiting reagent as it limits the formation of products. Acetylene is excess reagent as it is present in excess.

2 moles of acetylene C_2H_2 produce= 4 moles of carbon dioxide CO_2 .

33.6 moles of acetylene C_2H_2 produce= $\frac{4}{2}\times {33.6}=67.2$ moles of of carbon dioxide CO_2 .

Mole is the amount of substance that is equal to Avogadro's constant. 67.2 mole of Carbon dioxide produced when 35.0 mol acetone react completely.

Mole is the amount of substance that is equal to Avogadro's constant.

Given here,

$\bold{ 2C_2H_2 + 5O_2 \rightarrow 4CO_2 + 2H_2O}$

Means 2 moles of acetylene react with 5 moles of oxygen in the combustion reaction. to produce 4 moles of Carbon dioxide.

The molar ratio of Oxygen and acetylene is 5:2

The molar ratio of Acetylene and Carbon dioxide = 2:4

So, 84 moles of $\bold { O_2}$ , react with

$\bold{\Rightarrow \frac{2}{5} \times 84 = 33.6 mole }$ of acetone

hence,

33.6g of acetone react with

$\bold{\Rightarrow \frac{4}{2} \times 33.6 = 67.2}$ of Carbon dioxide

Therefore, we can conclude that 67.2 mole of Carbon dioxide produced when 35.0 mol acetone react completely.
