Burning of coal is represented as C(s)+O_(2)(g)rarr CO_(2)(g) . The rate of this reaction is increased by

Indicate the principle ingrediensts of the following A. Coal gas b. Producer gas c. Water gas d. Natural gas

C(s) + O_2(g) to CO_2(g) + 394kJ C (s) + 1/2 O_2(g) to CO + 111 kJ In an oven using coal (assume the coal is 80% C in weight), insufficient oxygen is supplied such that 60% of carbon is converted to CO_2 and 40% of carbon is converted to CO. Find out the heat generated when 10 kg of coal is burnt in this fashion.

A sample of coal gas contains 50% hydrogen, 30% methane, 14% CO and 6% C_2H_4 100 ml of this coal gas is mixed with 150 ml of oxygen and the mixture is exploded. What will be the composition of the resulting gas when it is to room temperature ?

Common variety of coal called household coal.

Coal and petrolem are called……………..fuels.

Coal gas is a mixture of:

Coal tar is the main source of
