Explanation:
Mg⁺²-24 Co⁺³-60 Clˉ-35
Protons (p⁺) 12 27 17
Neutrons (n⁰) 12 33 18
Electrons (eˉ) 10 24 18
(c) (b) (a)
12/2 : 12/2 : 10/2 27/3 : 33/3 : 24/3 #n⁰ = 18
6 : 6 : 5 9 : 11 : 8 #eˉ = 18
Explanation:
The equilibrium constant of the reaction =
Initial concentration of HI = 0.311 M
After addition 0.174 mol of HI(g)
Concentration of HI added =
New concentration of HI = 0.311 M + 0.174 M = 0.485 M
Initial concentration:
0.311 M
At equilibrium:
(0.485 M - x)
Equilibrium concentrations:
Answer:
The correct answer will be "".
Explanation:
We have:
Moles of solute (Na₂Co₃) =
=
=
Now,
The volume of the solution will be:
⇒
∴
The formula to find the concentration will be:
⇒
On substituting the given values, we get
⇒
⇒
Answer:
The sun is heavier than all of the planets, thus having more gravity
Explanation:
Because the sun is heavier, it exerts more gravitational pull towards itself, thus keeping all of the planets in orbit.
