Question

How many moles of CO2 are priloduced when 3.5 moles of C2H2 reacts?​

Answer 1

7mol of CO2

Step-by-step explanation:

The balanced equation for the combustion of acetylene is

`2C_(2) H_(2)+5O_(2)=4CO_(2)+2H_(2)O`

Using the equation coefficients, we can find out the number of moles of CO2 produced as follows.

`(3.5mol C_(2)H_(2))/(1) *(4CO_2)/(2 C_(2)H_(2)) =7molCO_(2)`
