The equilibrium constant Kc for the equation2H2(g) + CO(g) ⇌ CH3OH(g)is 35 at a certain temperature. If there are 3.21 ×10−2 mol
12345 [234]

Answer: the concentration of [CO]= 0.0532M

Explanation:

From The equation of reaction

2H2(g) + CO(g) ⇌ CH3OH(g)

Applying Kc= [CH3OH]/[H2]^2[[CO]

[CH3OH]= 0.00487

[CO]= x-0.00487

[H2]=(0.032-0.00487)^2=0.0271

Substitute into formula

Kc=[CH3OH]/[H2]^2[[CO]

35= 0.00487/(0.0271)^2(x-0.00487)

Simplify

x-0.00487=0.189

x= 0.00487+0.189=0.193moles

[CO]= n/C= 0.193/3.63= 0.0532M

What is the net ionic equation for barium sulphate
alexandr1967 [171]

The net ionic equation : Ba²⁺ + SO₄²⁻ ⇒ BaSO₄ (s)

<h3>Further explanation  </h3>

The electrolyte in the solution produces ions.  

The equation of a chemical reaction can be expressed in the equation of the ions  

In the ion equation, there is a spectator ion that is the ion which does not react because it is present before and after the reaction  

When these ions are removed, the ionic equation is called the net ionic equation  

For gases and solids including water (H₂O) can be written as an ionized molecule  

So only the dissolved compound is ionized ((expressed in symbol aq)  

Barium sulfate can be formed from the reaction:

Ba(NO₃)₂(aq) + Na₂SO₄(aq)⇒BaSO₄(s)+2NaNO₃(aq)

For full ionic equation :

Ba²⁺ + 2NO₃⁻ + 2 Na⁺ + SO₄²⁻ ⇒ BaSO₄ (s) + 2 Na⁺ + 2 NO³⁻

by removing spectator ions (2NO₃⁻ and 2 Na⁺), the net ionic equation :

<em>Ba²⁺ + SO₄²⁻ ⇒ BaSO₄ (s) </em>
