CO2
Ce added to

Answer 1

Unused oxygen is 2950 cc and volume of produced carbon dioxide is 600 cc.

Step by step explanation:

The chemical reaction is as follows.

$\bold{2C_{2}H_{6}+7O_{2}\rightarrow 4CO_{2}+6H_{2}O}$

From the reaction,

2 moles of ethane reacts with 7 moles of oxygen.

So, 300 cc of ethane reacts with

$=\frac{300\times7}{2}=1050cc$

Unused oxygen = (initial volume of oxygen - Final volume of oxygen)

                           = (4000 cc - 1050 cc) = 2950 cc

Therefore, unused oxygen is 2950 cc.

From the reaction,

2 moles of ethane reacts with 4 moles of oxygen.

So,300 cc of ethane produce

$=\frac{300\times4}{2}=600 cc$

Therefore, volume of produced carbon dioxide is 600 cc.
