Which element, if combined with chlorine, will have the greatest attraction for the chlorine electrons?

B) Ethane has the formula C2H6. In terms of electronic structure,

k0ka [10]

Answer:

There is one single covalent bond between two carbon atoms.

Explanation:

We know that sharing of electrons form covalent bonds.

If we look upon K,L,M ,N shells of the carbon and hydrogen atoms.

We found that Hydrogen is having only $1$ electron in K shell.

And Carbon on the other hand is having $2$ electrons in K shell and $4$ electrons in L shell.

So carbon have $4$ valence electrons,and it can share $4$ bonds with any relevant atom to complete its octet.

And Hydrogen requires $1$ electron to complete its doublet.

Alkane general formula $C_{n}H_{2n+2}$

For ethane $n=2$

$C_{2}H_{4+2}$ $=$ $C_{2}H_{6}$

$1$ Carbon atom is shared by $3$ Hydrogen.

The remaining one electron $(4-3)=1$ of carbon will be shared with another carbon atom.

An image of the sharing of electrons attached below,

Hence we have only $1$ covalent bond between the two.

A liquid mixture of 0.400 mole fraction ethanol and 0.600 methanol was placed in an evacuated (i.e., no air) bottle and after ma

deff fn [24]

Answer:

mole fraction methanol = 0.76

mole fraction ethanol = 0.24

Explanation:

Raoult´s law gives us the partial vapor pressure of a component in solution as the product of the mole fraction of the component and the value of its pure pressure:

PA = X(A) x Pº(A)

where PA is the partial vapor pressure of component A, X(A) is the mole fraction of A, and Pº(A) its pure vapor pressure.

From reference literature the pure pressures of methanol, and ethanol are at 25 ºC :

PºCH₃OH = 16.96 kPa

PºC₂H₅OH = 7.87 kPa

Given that we already have the mole fractions, we can calculate the partial vapor pressures as follows:

PCH₃OH = 0.600 x 16.96 kPa = 10.18 kPa

PC₂H₅OH = 0.400 x 7.87 kPa = 3.15 kPa

Now the total pressure in the gas phase is:

Ptotal = PCH₃OH + PC₂H₅OH = 10.18 kPa + 3.15 kPa = 13.33 kPa

and the mole fractions in the vapor will be given by:

X CH₃OH = PCH₃OH / Ptotal = 10.18 kPa/ 13.33 kPa = 0.76

X C₂H₅OH = 1 - 0.76 = 0.24

Consider the rate law below.

Inessa [10]

If you double the concentration of A, the rate is doubled. If you doubled the concentration of B, since the rate law has B^2, the rate is multiplied by 4. If you double both A & B's concentrations, then the rate would be multiplied by 2*4 = 8, which is the last option.
