Nothing is less dense than gas. gas is the least dense form of matter.
Right angle acute angle obtuse angle
Answer is: ammonia has a higher boiling point because it has stronger intermolecular forces.
Intermolecular forces<span> are the forces between </span><span>molecules. The stronger are intermolecular forces, the higher is boiling point of compound, because more energy is needed to break interaction between molecules.
</span>There are several types of intermolecular forces: hydrogen bonding, i<span>on-induced dipole forces, ion-dipole forces andvan der Waals forces.</span>
There's no math to this,
So I don't see why angle is in the question anyways...
The sun provides energy for animals and plants. A cave is a type of ecosystem that almost never sees the sunlight, and a forest is a type of ecosystem that sees the sunlight regularly. The difference between these two is- the caves have animals that have adapted to their environment, I think there's a species called ghost crabs that are blind and are white. This is because sunlight provides the vitamins to pigment skin. I could go on and on
Answer:
1.52M in NaCl
Explanation:
Molarity = moles solute / volume solution in Liters
=> molarity (M) = 3.8 moles / 2.5 Liters solution = 1.52 molar solution in NaCl
