Answer:
A.
Atoms cannot be created or destroyed by chemical reactions.
Explanation:
D) 60°C
Explanation:
The molecules of Nitrogen gas will have the highest average kinetic energy when their temperature is the highest.
According the kinetic molecular theory, the temperature of gases is directly proportional to their average kinetic energy.
The higher the temperature, the more kinetic energy they possess.
To find out the highest temperature from the given options, we need to solve and express all the given options in a single unit of temperature.
K = 273 + °C
Let us convert all to Kelvin;
-40°C;
K = 273 + (-40) = 233K
60°C;
K = 273 + 60 = 333K
We can see that 60°C has the highest temperature in kelvin and this will furnish the gas with the greatest average kinetic energy.

Answer:
hydrogen gas
Explanation: Magnesium combined with sulfuric acid produces magnesium sulfate and hydrogen gas
Explanation:
Hydrophobic means "water fearing" while polar molecules are hydrophilic meaning "water loving." Hydrophobic exclusion describes the tendency, for examples, of multiple oil droplets in water to coalesce into fewer, larger droplets
