D=m/v ⇒v=m / d
d=density
m=mass
v=volume
d(Benzene)=0.88 g/cm³
m=20.0 g
v=m/d
v=20.0 g / (0.88 g/cm³)=22.73 cm³
Solution: v=22.73 cm³=22.73 ml
- Lithium is very highly reactive
- Chlorine is very highly reactive
- Argon is unreactive.
<h3>What is the chemical reactivity?</h3>
The periodic table sort of makes it possible for us to be able to obtain the reactivity of the elements that are found in the periodic table. This is because, the reactivity of the elements that are in the periodic table generally depends on the group where the element is found in the table.
Lithium and chlorine are highly reactive because they are found in the first and the seventeenth groups of the periodic table which are known for the fact that they are very highly reactive.
Argon is found in group 18 thus it is not a highly reactive element.

Answer:
The moon's path around Earth is tilted compared to Earth's orbit around the sun. The moon can be behind Earth but still get hit by light from the sun. ... This is why we don't get a lunar eclipse every month.
Explanation:
Answer:
Explanation:
Using freezing point depression formula,
ΔTemp.f = Kf * b * i
Where,
ΔTemp.f = temp.f(pure solvent) - temp.f(solution)
b = molality
i = van't Hoff factor
Kf = cryoscopic constant
= 1.86°C/m for water
= (0 - (-5.58))/1.86
= 3.00 mol/kg
Assume 1 kg of water(solvent)
= (3.00 x 1)
= 3.00 mol.
