Air Pollution - Sulfur Dioxide

Explanation
Yes, it is a colorless gas because color is a visual property and gases do not have a definite shape or volume to reflect or absorb light, resulting in them being transparent and colorless.

Explanation
Sulfur dioxide is formed when fuel containing sulfur is burnt, reacting with oxygen to form sulfur dioxide. During the combustion process, the sulfur in the fuel combines with the oxygen in the air to produce sulfur dioxide as a byproduct. This reaction is commonly observed in industrial processes, as well as in the burning of fossil fuels such as coal and oil. Sulfur dioxide is a harmful gas that contributes to air pollution and can have negative effects on human health and the environment.

Explanation
Sulfur dioxide can be formed in smelting. Smelting is a process that involves heating and melting ores to extract metals. During this process, sulfur-containing minerals present in the ores can react with oxygen to form sulfur dioxide gas. This gas is released into the atmosphere and can contribute to air pollution. Therefore, it is possible for sulfur dioxide to be formed in smelting.

Explanation
Smelting is the process that emits the most sulfur dioxide. Smelting involves the extraction of metal from its ore by heating and melting it. During this process, sulfur dioxide is released as a byproduct. This is because many metal ores contain sulfur, and when they are heated, sulfur dioxide gas is produced. Transport and utilities may also emit sulfur dioxide, but smelting is known to be the process that releases the highest amount of this pollutant.

Explanation
Sulfur dioxide is a harmful gas that can cause various health issues. Eye irritation is one of the effects caused by exposure to sulfur dioxide, leading to redness, itching, and discomfort. Coughing is another symptom that can occur due to the irritation of the respiratory system caused by sulfur dioxide. Wheezing, characterized by a high-pitched whistling sound during breathing, is also a common effect. Additionally, sulfur dioxide can cause shortness of breath, making it difficult to breathe properly. These symptoms highlight the detrimental impact of sulfur dioxide on human health.
