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!

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
