Sulfur dioxide So2 is present in our atmosphere and is used as a preservative in foods. Is it possible to use the common charges
telo118 [61]

Answer:

Your question is not interpreted very well, but as regards what is observed, SO2 is not the formula for sulfur oxide, the formula for sulfur oxide is SO since the valence used in sulfur would be +2 and oxygen -2 therefore the sum of these valences would be equal to zero, therefore it would be the correct thing considering the true equation as SO

Explanation:

There are also sulfur dioxide, or sulfur trioxide, which is usually used in the formation of tertiary salts such as copper sulfate.

sulfur trioxide and sulfur dioxide are synonymous with sulfate or sulphite

An inflated balloon contains X air molecules.After some time the volume of the balloon is found to be the half at the same tempe
sladkih [1.3K]

Answer:

See explanation

Explanation:

According to Avogadro's law, the volume of a given mass of gas is directly proportional to the number of molecules of gas present at constant temperature and pressure.

Hence; V1/n1 = V2/n2

The implication of this is, if there were X molecules present and the volume of the balloon is halved, the number of molecules of gas present is also halved. So, we now have X/2 number of gas molecules present in the balloon.

This is in accordance with the statement of Avogadro's law.
