— Washing with soap and water is an effective way to destroy and dislodge many microbes
Explanation:
- Soap actually kill germs on our hands, it breaks them up and removes them
- .But soap molecules have two different ends to them.
- One end is attracted to water molecules – this is called hydrophilic
- – and the other end loves oil and fat molecules – this is called hydrophobic.
- Soap is able to bind to the oils on our hands, and then mix with the water to wash all the germs away.
Answer:
190 L
Explanation:
Given that:
Number of moles = mass/molar mass
number of moles = 5.64
molar mass of aluminum chloride = 133.34 g/mol
∴
The balanced equation is:
2 Al + 3 Cl2 --> 2AlCl3.
From above reaction:
5.64 mole of AlCl3 reacts with 3 mole Cl2 to give 2 mole AlCl3
i.e
= 8.46 mole Cl2 gas.
At Standard temperature and pressure:
= (22.4 L/1 mole gas) * (8.46 mole Cl2)
= 190 L chlorine gas
