He is using the filtration method.
It’s a technique which is used for separation of solids and fluids by putting them through a medium which allows only fluid to pass through, leaving the solids (in this case the soil) alone.
The fluid that passed is called the filtrate.
Explanation:
Involves combining of nuclei: Nuclear fusion
Nuclear fusion is a radioactive reaction in which small atomic nuclei combines into larger ones with the release of a large amount of energy. The energy released is used to furnish a series of chain reactions.
Produces dangerous radioactive waste: Nuclear fission
Nuclear fission is used in powering most nuclear power plants. The products of these reactions are radioactive in nature. They are very dangerous to human health and the environment at large.
Have high activation energies: Nuclear fusion
The activation energy is the energy barrier that must be overcome before a reaction starts. Nuclear fusion reactions require very high amount of energy input to overcome the activation needed to start the reaction.
Releases large amounts of energy: Nuclear reactions
Both nuclear fusion and fission releases large amount of energy.
Occurs in the stars: Nuclear fusion
Nuclear fusion occurs in stars and they involve the combination of atomic nuclei to form larger ones.
Drives chemical plants: Nuclear fission
Chemical plants uses electricity and nuclear power plants can produce electricity through nuclear fission.

Answer:
True.
Explanation:
To know which option is correct, let us calculate the number of mole present in 60g of calcium. This is illustrated below:
Mass of Ca = 60g
Molar Mass of Ca = 40g/mol
Number of mole Ca =....?
Number of mole = Mass/Molar Mass
Number of mole of Ca = 60/40
Number of mole Ca = 1.5 moles.
From the calculations made above, we can see that 1.5 moles are present in 60.0 grams of calcium
