A canister has a fixed volume. If the pressure of the cannister is 1.5 atm at 25 Celsius, what is the new pressure if the temper
scoray [572]

Answer:

<u>d) 1.8 atm</u>

Explanation:

<u>According to Boyle's Law,</u>

  • P₁/T₁ = P₂/T₂

Here, we are given :

  1. <u>P₁ = 1.5 atm</u>
  2. <u>T₁ = 25°C = 298 K</u>
  3. <u>T₂ = 75°C = 348 K</u>

<u />

<u>Solving</u>

  • P₂ = P₁T₂/T₁
  • P₂ = 1.5 x 348 / 298
  • P₂ = 522/298
  • P₂ = <u>1.8 atm</u> (approximately)

Suppose in an experiment to determine the amount of sodium hypochlorite in bleach, 0.0000524 mol K I O 3 were titrated with an u
11111nata11111 [884]

<u>Answer:</u> The amount of sodium thiosulfate required is 2.62\times 10^{-5} moles

<u>Explanation:</u>

Moles of KIO_3 solution given = 0.0000524 moles

The chemical equation for the reaction of potassium iodate and sodium thiosulfate follows:

2KIO_3+Na_2S_2O_3\rightarrow K_2S_2O_3+2NaIO_3

By Stoichiometry of the reaction:

2 moles of potassium iodate reacts with 1 mole of sodium thiosulfate

So, 0.0000524 moles of potassium iodate will react with = \frac{1}{2}\times 0.0000524=0.0000262mol of sodium thiosulfate

Hence, the amount of sodium thiosulfate required is 2.62\times 10^{-5} moles
