Option D: 246 K
According to ideal gas law:
...... (1)
Here, P is pressure, V is volume, n is number of moles, R is Universal gas constant and T is temperature of the gas. The value of R is 
.
Number of moles of gas are 0.750 mol, volume of cylinder is 6850 mL and pressure of gas is 2.21 atm.
First converting volume from mL to L
Thus,
6850 mL=6.850 L
Putting the values in equation (1),
Rearranging
,
Therefore, temperature of the gas is 246 K.

Answer:
Explanation: Over the course of a year, areas near Earth’s equator receive more direct energy from the Sun than areas near Earth’s poles. Which of the following correctly describes one result of this heating pattern?
it is because it reacts readily with other compounds
Answer:
High levels of nitrogen dioxide are also harmful to vegetation—damaging foliage, decreasing growth or reducing crop yields. Nitrogen dioxide can fade and discolour furnishings and fabrics, reduce visibility, and react with surfaces.
1-We could use low-nitrogen fuels
2- We could also modify combustion conditions to generate less NOx. Flue gas treatment techniques, such as selective cata- lytic reduction (SCR) processes, can remove NOx
