Answer:
The solid particles will be trapped behind on the strainer while the liquid molecules will pass or filter through.
Explanation:
Filtration is a process of separation of mixtures involving an insoluble solid and a fluid such as liquids or gases using a filtering medium such as paper or cloth or any other material. During the process, the liquid molecules pass through the filtering medium whereas the solid particles are not allowed to pass through but are retained by the medium. The reason is that the pores on the filtering medium are only small enough for the liquid molecules to pass through but not the solid particles.
An example of a mixture that can be separated through filtration is a suspension of chalk and water. Also, a mixture of water and solid particles such as water and tea leaves can also be separated using a strainer with cloth.
In the question, if a mixture of insoluble solids in a liquid is passed through a strainer with cloth, the solid particles will be trapped behind on the strainer while the liquid molecules will pass through.
C. They come from energy sources that never run out.
Answer:
C- Using a 0.35 g sample of Li(s) cut into smaller pieces will increase the rate of reaction
C- Equal quantities of gas will be produced with potassium K, used instead of Lithium, Li.
Explanation:
<u>First part</u>
When a metal is present in small pieces, the rate of the chemical reaction increases. This is due to small pieces provide more surface area for reaction than huge chunks of Li.
moles of reactant decreases product formation rate also decreases and temperature decreases rate also decreases so remaining option are wrong
<u>Second part
</u>
2Li + 2H2O --------------> 2LiOH + H2
2K + 2H2O ---------------> 2KOH + H2
Hence, both gives same quantity of gas
