Oxygen gas is formed when two oxygen atoms share electrons. which kind of compound is oxygen gas?

a) mesonic
b)covalent
c)ionic
d)polyatomic ion

There are two non metals therefore it’s covalent bonds if it was ionic then it would be a metal and a non metal combine . In this case we can see that oxygen is not a metal

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this you

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
