Answer:
[KIO₃] = 0.548 M
Explanation:
Molarity is a sort of concentration which involves moles of solute in 1L of solution.
Volume of solution 5L
Mass of solution: 587 g
Let's convert the mass to moles (mass / molar mass)
587 g / 214 g/mol = 2.74 moles
Molarity is mol/L → 2.74 mol / 5L = 0.548 M
To remember what the reactant is, it always comes before the yielding sign (arrow). The elements after the arrow are known as the 'products'.
So, with this information, let's look for our reactants.
Remember, the reactants are the elements BEFORE the yielding sign (arrow).
We have Hydrogen and Oxygen before the arrow.
Your answer is:
Hydrogen + Oxygen

Answer:
P = 0.444 atm
Explanation:
The reaction of decomposition of H₂S is:
H₂S(g) ⇄ H₂(g) + S(g)
<em>Initial</em> 0.245 0 0
<em>Equilibrium </em>0.245-x x x
The equilibrium constant (Kp) of the above reaction is the following:
(1)
Knowing that initally, only H₂S is present at P = 0.245, the Kp of equation (1) at equilibrium is:
Using the quadratic formula we get x₁ = 0.199 and x₂ = -1.058.
Taking only the possitive number we have that:
Therefore, the total pressure in the container at equilibrium is:
