Draw the Lewis structure with the lowest formal charges for ClF2+ . Include nonzero formal charges and lone pair electrons in th

e structure.
Chemistry
1 answer:
masya89 [10]3 years ago
4 0

Answer:

See explanation

Explanation:

The formal charge is obtained from;

Formal Charge = Valence electrons on atom - [number of bonds  - lone pair electrons]

The correct structure of ClF2+ is the structure attached to this answer (image obtained from quora) in which the formal charge on fluorine is zero and the formal charge on chlorine is + 1. This is the correct structure because the chlorine is more electronegative than fluorine as expected.

1.  A filter was used to separate the sand from the salt water solution (The process of decanting was used if a filer was not available).
2.  A Bunsen burner was used to boil away the water from the salt water solution leaving only salt.

I hope this helps.  Let me know if anything is unclear.

Calculate the standard entropy of vaporization of ethanol, C2H5OH, at 285.0 K, given that the molar heat capacity at constant pr
MArishka [77]

Answer: The standard entropy of vaporization of ethanol is 0.275 J/K

Explanation:

C_2H_5OH(l)\rightleftharpoons C_2H_5OH(g)

Using Gibbs Helmholtz equation:

\Delta G=\Delta H-T\Delta S

For a phase change, the reaction remains in equilibrium, thus \Delta G=0

\Delta H=T\Delta S

Given: Temperature = 285.0 K

\Delta H=78.3J/mol

Putting the values in the equation:

78.3J=285.0K\times \Delta S

\Delta S=0.275J/K

Thus  the standard entropy of vaporization of ethanol is 0.275 J/K

Diamond has a density of 3.26 g/cm^3. What is the mass of a diamond that has a volume of 25 cm^3?
givi [52]

Answer:

<h2>81.5 g</h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question we have

mass = 25 × 3.26

We have the final answer as

<h3>81.5 g</h3>

Hope this helps you
