Answer is: D. solid.
In solid, molecules are closely packed, stiff and do not changes of shape or volume. Solid object (for example iron) does not take on the shape of its container. Glass is disordered solid, known as an amorphous solid.
Liquids have definite volume, but no fixed shape, the atomic motions are slower and the atoms are closer together.
Gases (for example nitrogen and neon) not have definite volume and fixed shape, it depends on its container.

<em> Hi mate, here is ur answer:</em>
<em />
<em>You can </em><em>dissolve</em><em> more </em><em>salt</em><em> in </em><em>hot water</em><em> because in hot water, </em><em>molecules </em><em>move faster than </em><em>cold water</em><em> because of the </em><em>higher energy</em><em>, as a result the molecules of hot water move fast and </em><em>settles down</em><em>. As they settle fast, it is easy for higher amount of salt to dissolve in hot water. </em>
<em>HOPE THIS HELPS U</em>

Answer:
in the water, plants and small organisms like plankton take up mercury through passive surface absorption or through food intake. ... Methylmercury biomagnifies through the food chain as predators eat other organisms and absorb the contaminants that their food sources contained.

The third equation is properly balanced.
To figure this out, set up tables to check if each element has the same amount on both sides. If you do this for the third equation, copper, hydrogen, oxygen, and nitrogen are all balanced,
The first equation is incorrect due to the fact Iron, Fe, is not balanced on both sides. This is shown by the subscripts given.
The second equation is incorrect as Sulfur is not properly balanced and neither is sodium.
The fourth equation is incorrect as Aluminum is not properly balanced. On the reactants side, Aluminum is 4 while on the products, Aluminum is 8.
Hope this helps!
