Question
The air around smelting industries is likely to containA. H2S, CO and N2B. CO2, SO3 and H2C. H2, SO2 and CO2D. SO2, N2 and CO2
Solution
The air around smelting industries is likely to contain SO2, N2 and CO2. Therefore, the correct answer is D. SO2, N2 and CO2.
Here's why:
-
SO2 (Sulfur Dioxide): During the smelting process, sulfur-containing minerals can be converted into SO2, a gas that contributes to air pollution.
-
N2 (Nitrogen): Nitrogen makes up about 78% of the Earth's atmosphere, so it's almost always present in air samples.
-
CO2 (Carbon Dioxide): Smelting is a process that involves the reduction of ore using carbon as a reducing agent. This process produces CO2 as a byproduct.
So, the air around smelting industries is likely to contain these gases.

2. Sulphur dioxide gas, SO2 (g), when mixed with the air we breathe, can cause serious respiratory problems. The gas dissolves in the moisture in our lungs, creating an acid that causes burning in the lungs and throat. The World Health Organization (WHO) has set limits of 15.69 ppb (parts per billion) for an average 24-hour period. Many industrial processes, such as the smelting of metal ores, produce this gas. The air around a certain industrial plant was analyzed and found to have a concentration of SO2 of 23.85 ppb. If an average adult breathes in approximately 13.77 kg of air each day, what mass of SO2 would that person inhale?Ensure that units match.c = 23.85 ppbc = 23.85 g of SO 21 billion g of airSet up a ratio and solve.How many grams of SO 2 would be in 13.77 kg (13 770 g) of air?23.85 g of SO 2 is in 1 × 10 9 g of airx g of SO 2 is in 13 770 g of air23.85 = 1 x 10 9x 13770
