Answer:
the pressure exerted in pascals is 0.5 Pa
Explanation:
The computation of the pressure exerted in pascals is shown below:
As we know that
Pressure = force ÷ area
= 25 ÷ 50
= 0.5 Pa
Hence, the pressure exerted in pascals is 0.5 Pa
We simply applied the above formula so that the correct pressure could come
Answer:
They both are the same thing which is water but they are just in different forms.
Explanation:
A solid is water that is frozen and a liquid is just water.
To make any substance solid, molecules must come very close to each other. Substances with weak intermolecular forces have weak bonding. Hence to make their molecules come close to each other, we must provide low temperature.
Explanation:
First I'm going to draw the structure of the neutral calcium atom and the structure of the chlorine atom.
Now I'm going to draw only the valence shells of ions that participate in ionic bonding:
So Ca2+ will donate 2 electrons for both 2 atoms of Chlorine, forming CaCl2.
