Answer:
Ba
Explanation:
The trend for atomic radius is that it increases as you go down and decreases as you go right.
Kc = 3.2
The chemical equation is
2H2S ⇌ 2H2 + S2
The equilibrium constant expression is
<em>K</em>c ={[H2]^2[S2]}/[H2S]^2
1. Calculate the <em>equilibrium concentrations</em> of each component
[H2] = (4.0 mol)/(4.0 L) = 1.0 mol/L
[S2] = (0.80 mol)/(4.0 L) = 0.20 mol/L
[H2S] = (1.0 mol)/(4.0 L) = 0.25 mol/L
2. Calculate the value of the <em>equilibrium constant</em>
<em>K</em>c = (1.0^2 x 0.20)/0.25^2 = 3.2
Molarity : It is defined as the number of moles of solute present in one liter of solution.
Therefore, the molarity of solution is 3.33
1. the area would be 36
2. you would have to count trough each number until you have fully counted trough each dot example if there was a dot on -3 -2 trough 3 -2 you would have to count all the numbers untill you get trough -3 -2 to 3 -2
