Hello, Lilbabyy15. The answer would be F - False because the graph shows how much the population is growing exponentially (increasing). Have a great day!!

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:

d) 1.8 atm

Explanation:

According to Boyle's Law,

P₁/T₁ = P₂/T₂

Here, we are given :

P₁ = 1.5 atm
T₁ = 25°C = 298 K
T₂ = 75°C = 348 K

Solving

P₂ = P₁T₂/T₁
P₂ = 1.5 x 348 / 298
P₂ = 522/298
P₂ = 1.8 atm (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

Answer: The amount of sodium thiosulfate required is $2.62\times 10^{-5}$ moles

Explanation:

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
