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

The burning of what group of substances is a major source of sulfur dioxide in our atmosphere?

Which of the following reaction produces SO2 gas?Burning of sulphur in oxygenReaction of copper with H2SO4Roasting of sulphide oresBurning of H2S

Use the name of the product and the general equation given at the beginning of this chapter to complete the following equation:sulfur + oxygen →?Sulfur burns in oxygen to form sulfur dioxide.  Sulfur dioxide is sometimes used as a preservative for dried fruits, such as dried peaches and apricots and the guava rolls that many of us like so much. The fact that it is toxic means that very small amounts of it can be added to food to preserve it.In very small amounts, SO2 does not cause permanent damage to a large organism like a human, but bacteria cannot survive if it is present. Sulfur dioxide is also important as a preservative in many South African wines.  Class activity:The reaction between sulfur and oxygen.Above you wrote the word equation for the reaction between sulfur and oxygen.Did you write the following? sulfur + oxygen → sulfur dioxide🔴QUESTIONS:1. In which group is sulfur on the Periodic Table?2. What are the reactants for this reaction? Write down their names and formulas.3. What is the product of the reaction? Write down his name and formula4. Now use the formulas of the reactants and products to write a chemical equation.5. When is a reaction balanced?6. Is your reaction above balanced? Why do you say that?7. Draw a picture equation using the example of carbon above as a guide.
