Nitroglycerine is used as an explosive. The equation for the explosion reaction is: 4 C 3 H 5 ( NO 3 ) 3 ( l ) → 12 CO 2 ( g ) + 10 H 2 O ( l ) + 6 N 2 ( g ) + O 2 ( g ) What will be the total volume of gas (at rtp) from exploding 1 Kg of nitroglycerine?

Gram M r or mass of one mole of nitroglycerine is 227 g . Number of moles of nitroglycerine in 1 Kg = 1000 g 227 g ≈ 4 . 41 mol 4 C 3 H 5 ( NO 3 ) 3 ( l ) → 12 CO 2 ( g ) + 10 H 2 O ( l ) + 6 N 2 ( g ) + O 2 ( g ) Since, the equation shows that 4 moles of nitroglycerine on explosion produces 12 moles of carbon dioxide gas, 6 moles of nitrogen gas and 1 mole of oxygen gas. Therefore, one mole of nitroglycerine will produce 3 mol CO 2 , 1 . 5 mol N 2 and 0 . 25 mol O 2 . So, in total 4 . 75 mol of gas molecules are produced in the explosion. Moles of gas produced in the explosion of 4 . 41 mol of nitroglycerine = 4 . 41 × 4 . 75 = 20 . 95 mol Volume of one mole of gas at rtp = 24 dm 3 Therefore, volume of 20 . 95 mole of gas at rtp = 20 . 95 mol × 24 dm 3 = 502 . 8 dm 3

Since, one Kg of nitroglycerine can produce 502 . 8 dm 3 of gas. It has high nitrogen content and oxygen that can oxidise hydrogen and carbon meanwhile, nitrogen is liberated. This is a highly explosive reaction that creates high gas pressure and liberates heat which is why it is an exothermic reaction.

Nitrogen monoxide reacts with oxygen like this: 2 NO ( g ) + O 2 ( g ) → 2 NO 2 ( g ) How many moles of oxygen molecules react with 1 mol of nitrogen monoxide molecules?

Nitrogen monoxide reacts with oxygen like this: 2 NO ( g ) + O 2 ( g ) → 2 NO 2 ( g ) From the equation, it is clear that one mole of oxygen reacts with two moles of nitrogen monoxide. Therefore, half a mole of oxygen will react with one mole of nitrogen monoxide to give one mole of nitrogen dioxide.

Nitrogen monoxide reacts with oxygen like this: 2 NO ( g ) + O 2 ( g ) → 2 NO 2 ( g ) What volume of oxygen will react with 50 cm 3 of nitrogen monoxide?

Nitrogen monoxide reacts with oxygen like this: 2 NO ( g ) + O 2 ( g ) → 2 NO 2 ( g ) From the equation, it is clear that one mole of oxygen reacts with two moles of nitrogen monoxide. Therefore 25 Cm 3 of oxygen gas will react with 50 Cm 3 of nitrogen monoxide.

Nitrogen monoxide reacts with oxygen like this: 2 NO ( g ) + O 2 ( g ) → 2 NO 2 ( g ) What is the total volume of the two reactants, if nitrogen monoxide 50 cm 3 ?

Nitrogen monoxide reacts with oxygen like this: 2 NO ( g ) + O 2 ( g ) → 2 NO 2 ( g ) From the equation, it is clear that one mole of oxygen reacts with two moles of nitrogen monoxide. Therefore 25 Cm 3 of oxygen gas will react with 50 Cm 3 of nitrogen monoxide. Hence, the total volume of the reactants is 75 Cm 3 .
