6.1g of CNG is supplied with 208g of oxygen `CO_2` &`H_2O` is produced with a lot of heat how much `CO_2` is produced ?(consider CNG as methane)

1.5 g of oxygen is produced by heating KCIO_(3) . How much KCI is produced in the reaction? 2KCIO_(3)(s)rarr 2KCl_(s)+3O_(2)(g)

If 8.5 g of hexane burns completely in oxygen, how many moles of CO_(2) is/are produced?

Ethanol burns in excess oxygen to form CO_2(g) and H_2O(g) according to this balanced equation. C_2H_5OH(g)+3O_2(g) to2CO_2(g)+3H_2O(g) What value is closest to the volume of CO_2(g) , measured at 200 K and 1 atm produced from the combustion of 0.25 mol of C_2H_5OH(g) ?

When methane is burnt in oxygen to produce CO_(2) and H_(2)O . the oxidation number changes by:

Heat produced by burning 1 mol carbon with O_(2) to CO_(2) is 80 KJ and by maximum amount of heat produced on burning 30 g carbon with 48G O_(2) :
