3.75 litres is the volume of the balloon indoors at a temperature of 25°C.

Explanation:

Data given:

initial temperature of the gas in balloon = -35°C or 238.15 K

initial volume = 3 litres

final temperature = 25 °C or 298.15 K

final volume =?

pressure remains constant

From the data given when pressure is constant Charles' law is applied.

$\frac{V1}{T1}$ = $\frac{V2}{T2}$

Rearranging the equation to know the final volume of the gas in balloon

V2 = $\frac{V1T2}{T1}$

V2 = $\frac{3 X 298.15}{238.15}$

V2 = 3.75 Litres

when the temperature of a gas is increased and pressure remains constant the volume of the gas increases.

Consider the reaction.

Alex_Xolod [135]

Note the signs of equilibrium:-

Reaction don't procede forward or backward
Concentration of products and reactants remains same .

Concentration of A is 2M then concentration of B should be same .

So equilibrium constant K is 1

$\\ \rm\rightarrowtail K=\dfrac{[Products]^a}{[Reactants]^b}$

[B]=[A]^2
[B]=2^2
[B]=4M

Based on the activity series provided, which reactants will form products? F > Cl > Br > I CuI2 Br2 Right arrow. Cl2 Al

AleksAgata [21]

The reactants based on the reactivity capable of forming the products are $\rm CuI_2\;and\;Br_2$ . Thus, option A is correct.

The reactivity series has been the arrangement of the elements based on their reactivity. The highly reactive element has been capable of replacing the less reactive element in the compound, and form the product.

In the following reactions, the new product has been formed by:

$\rm CuI_2\;and\;Br_2$

From the reactivity series, Br has been more reactive than I, and thereby replaces iodine in the compound for the formation of product.

$\rm Cl_2\;and\;AlF_3$

The compound has been formed with F. Cl has been less reactive than F, and will not be able to form the product.

$\rm Br_2\;and\;NaCl$

The compound has been formed with Cl. Br has been less reactive than Cl, thus will not displaces Cl for the formation of new product.

$\rm CuF_2\;and\;I_2$

The compound has been formed with F. I has been less reactive than F, and will not be able to form the product.

The reactants that will be able to form the products have been $\rm CuI_2\;and\;Br_2$ . Thus, option A is correct.
