Everything dead would just keep piling up and up and up and nothing would ever go away! The Earth would be like a giant landfill! <span />
S + 2e⁻ → S²⁻ (sulfur will gain electrons)
Mg - 2e⁻ → Mg²⁺ (magnesium will lose electrons)
Magnesium is a metal which tends to give electrons which are received by the sulfur, which is a nonmetal and tends to gain electrons.
Condensation occurs in a condenser
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.
Answer:
D) 7 before and 7 after
Step-by-step explanation:
Na₂O + 2HCl ⟶ 2NaCl + H₂O
3 atoms + 4 atoms ⟶ 2×2 atoms + 3 atoms
7 atoms ⟶ 4 atoms + 3 atoms
7 atoms ⟶ 7 atoms
There are seven atoms present before and after the reaction.
