What is the equilibrium constant of 2H, 0 = 2H2 +0,?

AlexFokin [52]

Answer:

K = [H₂]² [ O₂] / [H₂O]²

Explanation:

The equilibrium constant of any reaction can be written as,

K = [product]/ [reactant]

For given reaction:

Chemical equation:

2H₂O → 2H₂ + O₂

equilibrium constant:

K = [H₂] [ O₂] / [H₂O]

In stoichiometric calculations, we will put the coefficient of balanced equation in given equilibrium constant equation.

K = [H₂]² [ O₂] / [H₂O]²

Attem A liquid solvent is added to a flask containing an insoluble solid. The total volume of the solid and liquid together is 9

monitta

Answer: The mass of solid is 105.4 g

Explanation:

To calculate the density of a substance, we use the equation"

$\text{Density of a substance}=\frac{\text{Mass of a substance}}{\text{Volume of a substance}}$ .......(1)

For liquid:

Mass of liquid = 26.6 g

Density of liquid = 0.865 g/mL

Putting values in equation 1, we get:

$0.865g/mL=\frac{26.6g}{\text{Volume of liquid}}\\\\\text{Volume of liquid}=\frac{26.6g}{0.865g/mL}=30.8mL$

We are given:

Volume of solid + Volume of liquid = 91.0 mL

Volume of liquid = 30.8 mL

So, volume of solid = 91.0 - 30.8 = 60.2 mL

Now, calculating the mass of solid by using equation 1, we get:

Volume of solid = 60.2 mL

Density of solid = 1.75 g/mL

Putting values in equation 1, we get:

$1.75g/mL=\frac{\text{Mass of solid}}{60.2mL}\\\\\text{Mass of solid}=(1.75g/mL\times 60.2mL)=105.4g$

Hence, the mass of solid is 105.4 grams
