Separating a mixture of salt and sand will involve two main techniques such as filtration and evaporation.
<h3>What is Filtration?</h3>
This is a technique which is used to separate a fluid from a solid matter such as sand etc.
Since salt dissolves in the water, the fluid is collected using the filter paper placed inside the funnel. After which it enters the Erlenmeyer flask and is heated to allow for evaporation of water and collection of the salt.

C The number and types of bonds within the molecule.
Explanation:
In a molecule, the number and types of bonds present determines the amount of available energy therein.
When bonds are broken or formed, energy is usually released.
- Elements combine with one another in order to attain stability in this state.
- Through this process, they form bonds by attraction.
- Where atoms exchange their valence electrons by losing or gaining it, electrovalent bonds form.
- In covalent molecules, electrons are usually shared between atoms.
- An attraction result from this type of interaction.
- The bond formed stores energy in the process.
- When bonds are broken, energy is usually released. The energy accrues when the bond was being formed.
- In molecules, we have covalent bond.

2.4 x 10²² atoms
<h3>Further explanation</h3>
Atomic mass is the average atomic mass of all its isotopes
In determining the mass of an atom, as a standard is the mass of 1 carbon-12 atom whose mass is 12 amu
So the atomic mass obtained is the mass of the atom relative to the 12th carbon atom
mass single Uranium atom=4.7 x 10⁻²² g
then for 111 mg=0.111 g
(4) C-14 Carbon is found in all living organisms.
