#1

Here the basic reaction of C and O_2 occurs hence


\\ \sf\bull\longmapsto {C\atop 1mol}+{O_2\atop 1mol}={CO_2\atop 2mol}

#2

First we have to find moles if Oxygen

  • Mass=16g.
  • Molar mass=16g/mol


\\ \sf\bull\longmapsto No\:of\:moles=(Given\:mass)/(molar\:mass)


\\ \sf\bull\longmapsto (16)/(16)


\\ \sf\bull\longmapsto 1mol

Hence

It will be same like 1st one i. e 2mols of CO_2 will be produced .

#3

Now we already found moles in 16g of dioxygen

Hence


\\ \sf\bull\longmapsto {C\atop 2mol}+{O_2\atop 1mol}\longrightarrow {CO_2\atop 3mol}
