Answer:

Grease is insoluble in water but soluble in kerosene

Explanation:

The molecules in grease are non polar molecules and so can not react with water which is polar to generate enough solvation energy. On the other hand kerosine is non polar so reacts with grease to generate enough solvation energy to dissolve it.

Which two terms relate and why? Compound, ion, proton
Lerok [7]

ion, proton

Explanation:

Ions and protons have profound relationships.

An ion is an atom that has lost or gained electrons.

A proton is a positively charged subatomic particle.

What is the relationship between an ion and a proton?

  • In an atom, there are three fundamental particles.
  • Protons are the positively charged particles located in the nucleus of atoms.
  • Electrons are the negatively charged particles orbiting round an atom.
  • Neutrons have no charges and they occupy the nucleus with protons.

Atoms are electrically neutral and this implies that they have equal number of protons and electrons.

In an ion, the number of protons and electrons differ.

For positive charged ions, the number of protons is more suggesting they have lost electrons.

For negatively charged ions. the number of protons is less suggesting they must have added electrons.

Compound are combinations of different atoms.
