Answer:
(A) A ball sitting on the ground
Explanation:
In a sample liquid water, a property that differs among the
water molecules is its own orientation and space. The explanation of the answer
to the question is because the number of the oxygen and hydrogen atoms and the
hydrogen and atoms’ arrangement will never change and will always be the same
for each of the water molecule. The strength of the bond of it also does not
change and stays the same.
C, The atomic mass. This could also cause certain elements (i.e. Uranium, Plutonium) to radioactively decay in process called nuclear fission.
<span>The best reason I can think of for why we believe that air is a mixture is that freezing air slowly yields different liquids at different temperatures. Liquid nitrogen has a different boiling point than liquid oxygen. They also freeze at different temperatures. If air were only 1 compound, then air in its entirety would have a single boiling point and a single freezing point. </span>
