Question

Find the value for Delta ng for C+O2---->CO2

Answer 1

Answer:

Δng = -1

Explanation:

Here    C + O2 ⇒CO2

we know  Δng = Gaseous moles of products - gaseous moles of reactants

= 1 - 2 = -1

Thanks :)

Answer 2

Answer:

∆ng=0

Explanation:

Though most will think that ∆ng = n(p)-n(r), it is to be remembered that it only works out for gases. However in this situation only O2 and CO2 are gases. C is a solid.

Hence ∆ng=np-nr

=1-1 = 0
