Answer:
Mg combines with SO2 to create MgO and S. When magnesium ribbon is burned in a sulphur dioxide-rich environment, the element magnesium reacts with the oxygen atom in the sulphur dioxide and burns constantly. This is a redox reaction (oxidation-reduction). Mg is a reducing agent, while SO2 is an oxidising agent.

<u>Answer:</u> The number of moles of gas in bicycle tire is 0.210 moles
<u>Explanation:</u>
To calculate the moles of gas, we use the equation given by ideal gas which follows:

where,
P = pressure of the gas = 737 torr
V = Volume of the gas = 5.30 L
T = Temperature of the gas = ![25^oC=[25+273]K=298K](https://tex.z-dn.net/?f=25%5EoC%3D%5B25%2B273%5DK%3D298K)
R = Gas constant = 
n = number of moles of gas = ?
Putting values in above equation, we get:

Hence, the number of moles of gas in bicycle tire is 0.210 moles
