Cartain mass of starach, (C_(6)H_(10)O_(5))_(n) , is burnt completely . If 26.4 kg CO_(2) is produced, the mass of water produced simultaneously is-

When 80 gm CH_(4) is burnt completely , CO and CO_(2) gases are formed in 1:4 mole ratio. What is the mass of O_(2) gas used in combustion.

The equation for the burning of octane is 2C_(8)H_(18) + 25O_(2) to 16CO_(2) + 18H_(2)O What is the empirical formula of octane ?

If 40 gm of methane is burnt, then how much amount of CO_2 is released ?

Toluence, C_7H_8 is added to gasoline to increase its octane rating. What is the volume ratio of air to tolane vapour to burn completely to from CO_2 and H_2O ? (Assume air is 20% O_2 by volume.)

1.250 g of a sample of octane (C_(8)H_(18)) is burnt in excess of oxygen in a bomb calorimeter. The temperature of the calorimeter rises from 298 K to 304.73 K. If heat capacity of calorimeter is 8.93 kJ/K. Calculate the heat transferred. Also calculate Delta U and Delta H of the reaction at 298 K. The reaction involved is C_(8)H_(18(l)) + (25)/(2)O_(2(g)) rarr 8CO_(2(g)) + 9H_(2)O_((l)) .

A mixture of C_(2)H_(2) and C_(3)H_(8) occupied a certain volume at 80 mm Hg. The mixture was completely burnt to CO_(2) and H_(2)O(l) . When the pressure of Co_(2) was found to be 230 mm Hg at the same temperature and volume, the mole fraction of CO_(3)H_(8) in the mixture is :
