When we write a formula of a compound in its simplest form, it is empirical formula.
Given the molecular formula is = C₁₈H₃₆
Now we can relate both empirical and molecular formula as;
Molecular formula = n x empirical formula
C₁₈H₃₆ = 18 x CH₂
So the empirical formula of C₁₈H₃₆ is CH₂
Answer:
Particles are constatantly moving and diffusing
This is possible because of diffusion

Answer:
Some chemical indicators perceived while a piece of paper is burning are:
Production of an Odor: there is a smell of burnt paper
Change in Temperature: combustion is a highly exothermic reaction , so the temperature increase
Change in Color: paper changes to ashes as the burning process occurs
Explanation:
-plants that can absorb copper ions are grown on soil with low grade copper ores.
-the plants are burned and the copper compounds are within the Ash.
-copper ions can be leached from the Ash by adding sulphuric acid, this makes a solution of copper sulphate
-the displacement of scrap iron makes pure copper metals.
