What happens when The vapour obtained by dropping conc. H2SO4 in a mixture of KI and MnO2 is treated with hypo solution​
Shalnov [3]

Iodine is decolorized.

The first reaction stated in the question occurs as follows;

2 KI (aq) + 2 H2SO4 (aq) + MnO2 (s) → MnSO4 (aq) + K2SO4 (aq) + I2 (s) + 2 H2O (l)

The reaction here is the formation of iodine from MnO2 and KI in the presence of dropwise H2SO4.

Hypo is the common name of sodium thio-sulphate or sodium hypo-sulfite.

The equation of the titration reaction is;

2Na2S2O3 + I2→ Na2S4O6 + 2NaI

When this reaction takes place, iodine is decolorized due to its reduction to I^-.

Given the value of the equilibrium constant (Kc) for the equation (a), calculate the equilibrium constant for equation (b)
matrenka [14]

Answer: The value of equilibrium constant for new reaction is 1.92\times 10^{-25}

Explanation:

The given chemical equation follows:

O_2(g)\rightarrow \frac{2}{3}O_3(g)+\frac{1}{2}O_2(g)  

The equilibrium constant for the above equation is 5.77\times 10^{-9}

We need to calculate the equilibrium constant for the equation of 3 times of the above chemical equation, which is:

3O_2(g)\rightarrow 2O_3(g)

The equilibrium constant for this reaction will be the cube of the initial reaction.

If the equation is multiplied by a factor of '3', the equilibrium constant of the new reaction will be the cube of the equilibrium constant of initial reaction.

The value of equilibrium constant for reverse reaction is:

K_{eq}'=(5.77\times 10^{-9})^3=1.92\times 10^{-25}

Hence, the value of equilibrium constant for new reaction is 1.92\times 10^{-25}

Assume prices increase from $15 to $18, yet quantity remains at 25. What is the total revenue?
UNO [17]

Given:

Number of items = 25

Price per item = $18

<u>To determine:</u>

The total revenue

<u>Explanation:</u>

Total revenue = quantity * price per item

                       = 25 items * 18 dollar/ 1 item = $450

Ans: A) The total revenue is $450
