Answer:
They allow particles to stay close together.
The attractive forces (bonds) in a liquid are strong enough to keep the particles close together, but weak enough to let them move around each other. For example, Liquids are useful in car brake systems because they flow and cannot be compressed.
Explanation:
Hope this helps :)
Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.

satellites, or the moons.
<span>These group
of heavenly bodies only revolve or orbit around planets. They are planet-like
globes that was clusters or excess during a certain planet’s formation. For
instance, plants like earth has 1 moon, Jupiter has 67 moons and etc. Futher, planets
on the other hand, are the ones that revolve under this massive hot ball of
thermal energy at the centre. In many cases, asteroids also actually revolve
under the sun, known as the asteroid belt, this is beyond the planet Mars. </span>
Solution:[tex]Let the molar mass of metal M is 'a',\\
\rn(so)\\
\frac{M_{o}}{2M_{H}+2M_{o}+a} =\frac{2.16}{2.1+2.16+a} =0.328\\
By simple algebric calculation. We get,\\ a=63.56g/mol\\
\rn(Now,)\\
We have to confirm which metal has the molar mass of 63.56g/mol. By using periodic table we have to find it the we get it is Copper(Cu).
Explanation:
The element that will have similar reactivity with sodium will be an alkali metal in Group 1 on the periodic table. The elements can be Li, K, Rb, Cs or Fr.
- Group 1 elements have just one valence electron and they are purely electropositive metals.
- They are usually very reactive and not found easily in free state in nature.
- Chemical reactivity is a similar property in a group. It is known that elements in the same group will react in the same way.
- Chemical reactivity is a function of the valence electrons.
- All group 1 elements have just an electron in their valence shell.
