Of the following, ________ is the most volatile. Select one: C2F6 C2H6 C2I6 C2Cl6 C2Br6

Answers

Answer 1

Answer:

C2Br6

because bromine is a liquid volatile

Answer 2

According to the forces of attraction and boiling point C₂Br₆ is most volatile as its boiling point is very low.

What are forces of attraction?

Forces of attraction  is a force by which atoms in a molecule  combine. it is basically an attractive force in nature.  It can act between an ion  and an atom as well.It varies for different  states  of matter that is solids, liquids and gases.

The forces of attraction are maximum in solids as  the molecules present in solid are tightly held while it is minimum in gases  as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.

The physical properties such as melting point, boiling point, density  are all dependent on forces of attraction which exists in the substances.

Answers

Answer:

First we know that the molar mass of CO2 is 44.01g/mol, and that the sample of CO2 contains 3.408 x 10^21 molecules, and we have to find the mass of that sample.

We know that moles = mass/molar mass, if we rearrange the equation for mass, we'll get:

mass = moles x molar mass

Also, note that the number of atoms/molecules in a sample is the moles of the sample x Avogadro's number (6.02 x 10^23)

If we rearrange the equation for moles, we would get:

moles = molecules of sample/6.02 x 10^23

Plug in the values for the equation above to get the moles:

moles = (3.408 x 10^21)/(6.02 x 10^23)

moles = 0.00566112956 (we're not done yet)

Now that we have the moles and we were already provided the molar mass, we can calculate the mass using the very first equation we rearranged.

mass = moles x molar mass

mass = 0.00566112956 x 44.01

mass = 0.2491g (answered 4 places past the decimal point)

Therefore the sample of Carbon Dioxide has a mass of 0.2491g

How do ionic and molecular compounds behave in water?

Answers

Ionic compounds dissolve in water by a process called dissociation. Water molecules separate the cations and ions by means of ion-dipole attractions to form hydrated ions.

Answer:

When ionic compounds dissolve in water they go through a process called dissociation, splitting into the ions that make them up. However, when you place covalent compounds in water, they typically do not dissolve but form a layer on top of the water.

Octane has a density of 0.703 g/ml. Calculate the mass of CO2(g) produced by burning one
gallon of octane. There are 3.79 liters to one gallon.

Answers

The mass of CO₂ gas produced during the combustion of one gallon of octane is 8.21 kg.

The given parameters:

Density of the octane, ρ = 0.703 g/mlVolume of octane, v = 3.79 liters

The mass of the octane burnt is calculated as follows;

[tex]m = \rho V\\\\m = 0.703 \ \frac{g}{ml} \times 3.79 \ L \ \frac{1000 \ ml}{L} \\\\m = 2,664.37 \ g[/tex]

The combustion reaction of octane is given as;

[tex]2C_8H_{18} + \ 25O_2 \ --> \ 16CO_2 \ + \ 18H_2O[/tex]

From the reaction above:

228.46 g of octane -------------------> 704 g of  CO₂ gas

2,664.37 of octane --------------------> ? of CO₂ gas

[tex]= \frac{2,664.37 \times 704}{228.46} \\\\= 8,210.3 \ g\\\\= 8.21 \ kg[/tex]

Thus, the mass of CO₂ gas produced during the combustion of one gallon of octane is 8.21 kg.

If the vapor pressure of water at 20.0 o C is 17.535 torr, and the atmospheric pressure measured by a barometer was 757.3 torr, what is the partial pressure of H2 in the gas mixture in a buret

Answers

Answer:

f the vapor pressure of water at 20.0 o C is 17.535 torr, and the atmospheric pressure measured by a barometer was 757.3 torr, what is the partial pressure of H2 in the gas mixture

Partial pressure of H2 in gas mixture is :

739.765 torr .

Explain total pressure?The overall pressure ptot is the total of all pressures in a reference system. This pressure, according to Bernoulli (see Fluid mechanics), consists of the static pressure p, the dynamic pressure pdyn, and the geodetic component ( g z) that exists in a fluid along a stream line in a frictionless flow.The total pressure of a gas mixture is the sum of its component gases' partial pressures: Ptot = ∑Pi = P1 + P2 + P3... ntot = total number of moles in the gas mixture (the sum of all ni).

Total  pressure of mixture =

Partial of hydrogen + Partial pressure of oxygen

Partial of Hydrogen = Total pressure - partial   pressure  of  oxygen

Here total pressure = 757.3 torr

Partial pressure of oxygen = 17 . 535 torr

Total pressure = 757 . 3 - 17 . 533

                        = 739.765 torr.
