Answer:
The valence electrons are involved in the chemical bonds.
Explanation:
In chemical bonds, atoms lose, gain or share electrons. The valence electrons (those located in the last energy level) in the chemical bonds are involved. These links are made to comply with the law of the octet (complete 8 electrons in the last energy level), for the chemical stability of the atoms.
You can use any form of the Ideal Gas Law, but usually one form is more convenient, depending on the information given.
There are three forms of the Ideal Gas Law.
Form 1
P
V
=
n
R
T
If the question gives you the number of moles then
, this is the most convenient one to use.
Form 2
P
V
=
m
M
R
T
, where m is the mass of the gas and
M is its molar mass.
If the question gives you the mass
m
, this is the most convenient one to use.
Form 3
P =
ρ
M
R
T
, where ρ is the density of the gas.
If the question gives you the density
ρ
, this is the most convenient one to use.
Answer:
well hello there ms gabby I might not know the answer but you could text me on Ig or sc

ur really pretty
The mass of ore required is
21 700 t.
r = 750 cm
V =
=
= 1.767 × 10⁹ cm³
The density of lead is 11.34 g/cm³.
So mass of lead sphere = 1.767 × 10⁹ cm³ ×
= 2.004 ×10¹⁰ g
2.004 ×10¹⁰ g ×
= 2.004 × 10⁷ kg
2.004 × 10⁷ kg ×
= 2.004 × 10⁴ t
92.5% efficiency means 92.5 t Pb per 100 t of ore.
Mass of ore = 2.004 × 10⁴ t Pb ×
= 2.17 × 10⁴ t ore = 21 700 t ore
I’m pretty sure the correct answer is It provides temperature regulation.
Water has a high heat capacity, which means it can absorb a big amount of energy before altering temperature. Because the body may be exposed to numerous settings and experience tiny temperature variations, this helps it manage heat.
I hope this was helpful. Please let me know if there is anything that is unclear.
