Answer:
9.4
Explanation:
The equation for the reaction can be represented as:
+ 
⇄ 
The ICE table can be represented as:
+ 
⇄
Initial 0.27 0.49 0.0
Change -x -2x x
Equilibrium 0.27 - x 0.49 -2x x
We can now say that the concentration of at equilibrium is x;
Let's not forget that at equilibrium = 0.11 M
So:
x = [] = 0.11 M
[] = 0.27 - x
[] = 0.27 - 0.11
[] = 0.16 M
[] = (0.49 - 2x)
[] = (0.49 - 2(0.11))
[] = 0.49 - 0.22
[] = 0.27 M
![K_C = \frac{[CH_3OH]}{[CO][H_2]^2}](https://tex.z-dn.net/?f=K_C%20%3D%20%5Cfrac%7B%5BCH_3OH%5D%7D%7B%5BCO%5D%5BH_2%5D%5E2%7D)
= 9.4
∴ The equilibrium constant at that temperature = 9.4
The chemical formula would dictate how many ions are present in a solution. It tells how many of what ion would dissociate in the solution. In every chemical reaction or dissociation reaction, it is important to remember that the number of each atoms on each side would be equal.
Mass of Oxygen : 8 g
<h3>Further explanation</h3>
Given
48g of Magnesium
32g of Oxygen
Required
Mass of Oxygen
Solution
The ratio of Mg and O in MgO :
48 g : 32 g = 3 : 2
Total ratio = 3+2 = 5
So for 20 g MgO, mass of Oxygen :
=2/5 x 20 g
=8 g
Or
%mass O = 32/80 x 100%=40%
mass O in 20 g MgO =
40% x 20 g =8 g
<h3>0.020 × 1000 × 100</h3>
<h2>= 2000 mg of Sn</h2>
hope that helps !
