An unknown sample weighing 0.3512g was added to 20.0 mL of cyclohexane. The density of cyclohexane is 0.779g/mL, and the freezin

rjkz [21]

Explanation:

It is known that density is mass of a substance divided by its volume.

Mathematically, Density = $\frac{mass}{volume}$

Therefore, calculate the mass of cyclohexane as follows.

mass of cyclohexane = Density × volume

= $0.779 g/mL \times 20 mL$

= 15.58 g

or, = 0.01558 kg (as 1 kg = 1000 g)

As, K_{f} of cyclohexane = $20^{o}C/m$

$\Delta T_{f} = K_{f} \times molality$

$5.2 = 20 \times molality$

molality = $\frac{5.2}{20}$

= 0.26 m

Also, molality is the number of moles of solute present in kg of solvent.

Mathematically, molality = $\frac{\text{no. of moles}}{\text{mass of solvent}}$

0.26 = $\frac{\text{no. of moles}}{0.01558}$

No. of moles = $4.05 \times 10^{-3}$

As, No. of moles = $\frac{mass}{\frac{molar mass}}$

$4.05 \times 10^{-3} = \frac{0.3512}{\text{molar mass}}$

molar mass = 87.0 g/mol

Thus, we can conclude that molar mass of unknown substance is 87.0 g/mole.

A 8.249 gram sample of copper is heated in the presence of excess fluorine. A metal fluoride is formed with a mass of 13.18 g. D

levacccp [35]

Answer:

$CuF_2$ the empirical formula of the metal fluoride.

Explanation:

Mass of copper heated = 8.249 g

Mass of copper fluoride formed = 13.18 g

Mass of fluorine gas in copper fluoride = x

$13.18 g = 8.249 g + x\\x= 13.18 - 8.249 g = 4.931 g$

Moles of copper :

$= \frac{8.249 g}{63.546 g/mol}=0.1298 mol$

Moles of fluorine:

$= \frac{4.931 g}{18.998 g/mol}=0.2596 mol$

For the empirical formula divide the smallest mole of an element with all the moles of elements present in the compound.

$Copper= \frac{0.1298 mol}{0.1298 mol}=1\\Fluorine = \frac{0.2596 mol}{0.1298 mol}=2$

The empirical formula of the copper fluoride = $CuF_2$

$CuF_2$ the empirical formula of the metal fluoride.

How do emulsifiers help oil and water to mix and not separate?

Olin [163]

Answer:

To prevent the mixture from separating substances called emulsifiers can be added. These help to form and stabilise the emulsions, preventing or slowing the water and fat/oil from separating. ... The hydrophilic end of the emulsifier molecule is attracted to the water and the hydrophobic end is attracted to the fat/oil.

Amobarbital sodium react with ethanolic sodium hyrooxide

CaHeK987 [17]

Amobarbital (like all barbiturates) works by being incontestible to the GABAA receptor at either the alpha or the beta subunit.

<h3>What is the mechanism of amobarbital?</h3>

Amobarbital (like all barbiturates) works by binding to the GABAA receptor at either the alpha or the beta subunit. These are compulsory sites that are distinct from GABA itself and also distinct from the benzodiazepine binding site.

Amobarbital is a barbiturate classified as having a halfway duration of action, meaning that the effects of the drug can last from 4-6 amobarbital increases the effects of benazepril by apparatus: pharmacodynamic synergism.

So we can conclude that Amobarbital, 5-ethyl-5-isoamyl barbituric acid like all barbiturates.

How does kinetic energy relate to particles and the states of matter?<br> Help??

harkovskaia [24]

Answer:

The kinetic molecular theory of matter states that: Matter is made up of particles that are constantly moving. Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy. The temperature of a substance is a measure of the average kinetic energy of the particles.
