Answer:
To find the noble gas notation, you first take the noble gas before the element you’re trying to find the notation for. In this case, the noble gas before Calcium is Argon. You put the symbol for Argon in square brackets, and then you write out the rest of the notation as you would normally.
This would look like [Ar]4s^2
The 4s^2 is because Calcium is the second element in the 4s columns (refer to the diagram)
Hope this helps :)
Answer:
1.2 M
Explanation:
Let's consider the following reversible reaction.
CuS(s) + O₂(g) ⇌ Cu(s) + SO₂(g)
To find the equilibrium concentration of O₂ we will use an ICE Chart. We will only consider gases and aqueous species since the activity of solids and liquids is 1.
CuS(s) + O₂(g) ⇌ Cu(s) + SO₂(g)
I 2.9 0
C -x +x
E 2.9-x x
The equilibrium constant (Kc) is:
![Kc=1.5=\frac{[SO_{2}]}{[O_{2}]} =\frac{x}{2.9-x} \\x=1.7](https://tex.z-dn.net/?f=Kc%3D1.5%3D%5Cfrac%7B%5BSO_%7B2%7D%5D%7D%7B%5BO_%7B2%7D%5D%7D%20%3D%5Cfrac%7Bx%7D%7B2.9-x%7D%20%5C%5Cx%3D1.7)
The concentration of O₂ at equilibrium is:
[O₂] = 2.9 -x = 2.9 - 1.7 = 1.2 M
