Answer:
1st Question: A
2nd Question: B
Explanation:
The 1st answer would be A because if a sample is at absolute zero then the sample is at its lowest temperature none of the molecules would be able to move, this is because lower temperature= lower kinetic energy.
The 2nd answer would be B because if a sample has more temperature it speeds up it has more temperature and more kinetic energy, meaning it would move faster because there is more temperature.

The most likely formula for an oxide formed between group 1a atom X and oxygen would be
X2O. - X is group 1a atom.
Answer:
<h2>volume = 3.63 mL</h2>
Explanation:
The density of a substance can be found by using the formula
<h3>

</h3>
Since we are finding the volume
Making volume the subject we have
<h3>

</h3>
From the question
mass = 63.6 g
Density = 17.5 g/mL
Substitute the values into the above formula and solve for the volume
That's
<h3>

</h3>
We have the final answer as
<h3>volume = 3.63 mL</h3>
Hope this helps you
