Answer:
Definitely not. This is because the alkaline earth metal [basically group 2 elements] are reactive and will react with the contents of the can, contaminating it.
D. because the size and shape of the slope determines weather the load can be sustained and c is correct too because the shape affects how much you can load and b. is correct as also because if the volume is very large it can affect the rivers load and flow.

<h2>_____________________________________</h2><h3>BLACK HOLES:</h3>
A black hole is a region of spacetime where gravity is so strong that nothing no particles or even electromagnetic radiation such as light can escape from it. Black holes are caused because of a supernova. A supernova is an exploding star that blasts part of the star into space.
<h2>_____________________________________</h2><h3>Why does it have so strong gravity?</h3>
The gravity is so strong because matter has been squeezed into a tiny space. That means, the large mass centers into the small diameter so Large mass comes in the small diameter which makes the strong gravity.

The mercury (Hg) has 80 electrons. The electrons are distributed in the s, p, d and f orbitals. The electronic configuration of Hg can be shown as-
. We can see that there are two filled d-orbitals 3d and 4d. There is only one filled f orbital which is 4f. The electron cloud of the s, p, d and f are different due to their different screening and penetration effect towards the nucleus. The electron cloud of f-orbital is most diffuse than the other three. The outermost electrons of mercury is
, which is its valence electrons i.e. (+2).
