Yes, I believe we would have fewer cases of infections. For example, the mosquito virus that was going around is more common in wetter areas because mosquitos are attracted to water.

While a balloon is being filled, if the temperature of the air in the balloon increases, what happens to it’s volume?
faust18 [17]

When heating up, the balloon slowly rises and flies up in the air again. Explanation: The volume of the balloon decreases by the low temperature, because the gas inside is cooled down. When heated up, the pressure in the balloon rises, the balloon expands, and will reach to its original shape.

Believe it!!

What is the balanced form fir Na(s) + ao2(g) = Na2O(s)​
Dima020 [189]

Answer:

Balanced Chemical equation:

4Na + O₂ → 2Na₂O

Explanation:

Chemical equation:

Na + O₂ → Na₂O

Balanced Chemical equation:

4Na + O₂ → 2Na₂O

Four mole of sodium combine with one mole of oxygen and form two mole of sodium oxide.

Coefficient with reactant and products:

Na   4

O₂     1

Na₂O  2

Oxygen is present in group sixteen and have six valance electrons. while sodium is alkali metal and present in group one and have one valance electron.

Oxygen needs two electron to complete the octet while sodium need to lose the one electron to get the complete octet.

When oxygen is combine with sodium it gain its two valance electrons from two sodium atom and form anion while sodium loses its valance electron to wards oxygen and form cation. The bond form between them is ionic because one is metal and other is non metal and electrons are completely transfer from two sodium atom to one oxygen atom.
