I thinlk it's by radiation?......
There is a typo in the question. hopefully, i assumed the correct number.
when volume and temperature are given, that means you need Charles' law. remember that with any gas formula, the temperature has to be in Kelvin which can be determined by simply adding 273 to Celsius.
Charles' law---> V1/T1 = V2/T2
V1= 2.8 m3
T1= 20 C = 293 K
V2= 0.2 m3
T2= ????
let's plug in the values
2.8/ 293 = 0.2/ T2
T2= 20.9 Kelvin
to change the answer to Celsius, just subtract 273 to the temperature
20.9 - 273= -252 Celsius
Given what we know about the mechanisms surrounding weather, we can confirm that Large deserts receive less rainfall due to the lack of bodies of water and "rainshadows".
- Rainshadow is a term used to describe the effects of nearby mountains on the rainfall amounts of a desert. The mountain causes the air to rise greatly and lose moisture. This moisture is received by the mountain, <em><u>which means that it does not reach the desert area. </u></em>
- Another limiting factor for the amount of rainfall received by deserts is the lack of bodies of water in the area. Once a desert is formed, <em>it tends to lack large bodies of water</em>. This limits the rainfall it receives given that there is no water nearby to evaporate and <em><u>cause the formation of clouds. </u></em>

Answer
Mole ratio of magnesium to Oxygen will be too low.
Explanation:
When magnesium burns in air, it reacts with oxygen vigorously to form an ionic compound,MgO with a flame that is a brilliantly white. Normally, stability of an atom depends on whether their outermost shell contains maximum electrons. Durning combination with Oxygen, Magnesium tends to give two of its electron causing it to be stable because it has a full outermost shell. It forms Mg+2 ion, Oxygen, on the other hand gains the two electrons, which fills its outermost most shell. It also now has more electrons than protons
The MOLE RATIO of magnesium to oxygen would be too low, because there will be MORE oxygen present than there should have been.
