Question

How do you separate the compounds of a mixture of sugar and sand? Would your methods result in physical or chemical changes?

Answer 1

Hint: We have to remember that the water is one of the important things for surveys in the world. Without water nothing in the world. Plant photosynthesis also depends on the water. In Human being metabolism, water plays a vital role. The molecular formula of water is \[{{\text{H}}_{\text{2}}}{\text{O}}\]. Water has one oxygen atom and two hydrogen atoms. The molecular weight of the water is \[18g\].

Complete answer:
The mixture of sand and sugar is given,
We want to separate sand and sugar.
The sand does not dissolve in water and sugar dissolves in water.
In this way we can separate sand and sugar.
In these methods results in physical or chemical changes sand and sugar in water is,
The sand does not dissolve in water and sand settles down the solution and sometimes becomes a suspension nature.
The sugar dissolves in water and here sugar acts as a solute and water acts as solvent and it becomes a clear solution.

Note:
We need to know that in chemistry, periodic tables play a vital role. In the periodic table there are totally \[118\] elements. In the periodic table there are totally \[18\] columns and \[7\] rows. The columns are called groups. Hence, \[18\] groups in the periodic table. The rows are called periods. Hence, totally \[7\] period in the table. Hydrogen and oxygen are the one of the elements in the periodic table. Hydrogen is the first element in the periodic table. The atomic number of hydrogen is \[1\]. The symbol of hydrogen is \[{\text{H}}\]. The mass number of hydrogen is \[1\]. The atomic number of oxygen is \[8\]. The symbol of oxygen is \[{\text{O}}\]. The mass number of oxygen is \[16\].
