Moles of O₂ = 3.92

<h3>Further explanation</h3>

Given

V=1 L

T=-118 °C + 273 = 155 K

P = 49.77 atm

Required

moles of O₂

Solution

the gas equation can be written

$\large {\boxed {\bold {PV = nRT}}}$

where

P = pressure, atm

V = volume, liter

n = number of moles

R = gas constant = 0.08206 L.atm / mol K

T = temperature, Kelvin

Input the value :

n= PV/RT

$\tt n=\dfrac{49.77~atm\times 1~L}{0.082\times 155}=3.92~moles$

A student needed to dissolve a substance that she knew was soluble in water. according to the chart, which other solvent would m

Dmitry [639]

The chart is attached below and the options are as follow,

A Benzene

B Methanol

C Hexane

D Octane

Answer:
Option-B (Methanol) is the correct answer.

Explanation:
As we know that the substance given to student is soluble in water. Therefore, those substances which are soluble in water are polar in nature because water is polar in nature and Like Dissolves Like.
Hence, in chart it can easily be seen that Methanol is also polar in nature due to presence of -O-H (polar) bond. So, the substance will dissolve in it.

A chemist must prepare 200.0 mL of hydrochloric acid solution with a pH of 0.60 at 25 °C. He will do this in three steps: • Fill

Likurg_2 [28]

Answer:

In the second step, the chemist must measure 8.3 ml of concentrated acid

Explanation:

The concentration of the final solution can be obtained using the pH value:

pH = -log[H] = 0.60

[H] = 10^(-0.60) = 0.25 M

Then, the final concentration of HCl will be 0.25 M because HCl is a monoprotic acid, which means that HCl only has one hydrolyzable proton. Therefore: [HCl] = [H].

The number of moles of HCl in the final solution will be equal to the number of moles present in the volume taken from the stock solution:

n° of moles in the volume taken from stock solution = n° moles in the final solution.

The number of moles can be calculated as follows:

number of moles = concentration * volume

Then:

Ci * Vi = Cf * Vf

where

Ci = concentration of the stock solution

Vi = volume taken from the stock solution

Cf = concentration of the final solution

Vf = volume of the final solution

Replacing with the data, we can obtain Vi:

6.0 M * Vi = 0.25 M * 200.0 ml

What is reduction potential?

Shtirlitz [24]

Answer:

A reduction potential measures the tendency of a molecule to be reduced by taking up new electrons. ... Standard reduction potentials can be useful in determining the directionality of a reaction. The reduction potential of a given species can be considered to be the negative of the oxidation potential.
