When 0.3 moles of acetylene is burned , total mole number of the products will be? a- 0.30 mol b-0.60 mol c-0.75 mol d-0.90 mol e- 1.2 mol

d. 0.9 mol

Explanation:

On this case we have to start with the formula of acetylene:

Now we can write the chemical reaction of combustion:

The next step is to balance the reaction:

The molar ratio between and is 2:4, so:

The molar ratio between and is 2:2, so:

The total moles would 0.6 + 0.3=0.9 moles.

I hope it helps!

h let me think

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.
