Question

A certain sample of coal contains 1% sulphur by mass. What is the weight of the so2 produced when 2×10^6kg of this coal is burnt

Answer 1

Answer:

Acidified water was electrolysed using an inert electrode and volume of gases liberated at stp was 168 ml. The amount of electricity ... 3x = 168 ml = 0.168 l x = 0.056 l

Answer 2

Explanation:

when the coal is burned, the sulfur is converted to sulfur dioxide. to prevent air pollution, this sulfur dioxide is treated with calcium oxide (cao) to form calcium sulfite (caso3). calculate the daily mass (in kilograms) of cao needed by a power plant that uses 5.00 × 106 kg
