In looking at the bolded atoms in the answer choices, which pair consists of molecules having the same geometry?

2 answers:

7 0

Correct Answer: option C:The pair which consist of molecules having the same geometry is CH2CCI2 and CH2CH2.

Reason:
Both of the above molecules contain double bonds. They are characterized by sp^2 hybridization. Also, they possess a trigonal planar geometry. In trigonal planar system, the molecule consist of three equally spaced sp^2 hybrid orbitals, which arranged at angle 120 degree.

The choices given were:

PCl3 and BF3

CH2O and CH3OH

CH2CCl2 and CH2CH2

CO2 and SO2

The correct option is CH2CCl2 and CH2CH2 because both of them contains a double bond which is sp^2 hybridized and it shows a trigonal planar geometry.

How do scientists know That the human activity is the major force behind climate change?

ziro4ka [17]

Answer:

It is because of Various things that we do, If we did not exist, several animals that went extinct because of us, would have thrived, If it wasn't for us filling the sky with so much CO2's, we wouldn't have the Earth heating up even more. Also, other things that we do such as Urbanization, Desertification, and Deforestation. All of these words will be defined under this text.

Explanation:

Deforestation: When humans cut down too many trees can result in habitat loss/ more CO2's

Desertification: When land used to be a grassland but humans used too much of a resource and turned it into a hot, sandy wasteland.

Urbanization: When you take land and fill it with tons of buildings, homes, and businesses. This can result in over-crowding, and spreading of diseases.

A balloon at 30.0°C has a volume of 222 mL. If the temperature is increased to 56.1°C and the pressure remains constant, what wi

svp [43]

Answer:

<em>415.15 mL</em>

Explanation:

To solve the statement, you can use the law of Charles - Gay Lussac, which states that "<em><u>the volume of gas is directly proportional to its temperature at constant pressure</u></em>." Mathematically:

$\frac{V1}{T1} = \frac{V2}{T2} = Constant$

You can calculate the volume V₂ Clearing it from the equation and replacing the values granted by the statement to perform the calculation:

V₂ = V₁ x T₂ / T₁ = 222 mL x 56.1 ° C / 30.0 ° C = 415.15 mL

Therefore, <em>the gas at 56.1 ° C will occupy a volume of 415.15 mL</em>

22.4 liters of a gas at a constant temperature of zero Celsius and a pressure of 1 atmosphere is compressed to a volume of 6.2 l

zhannawk [14.2K]

<h2>Hello!</h2>

The answer is: The new pressure of the gas is 3.6 atm.

From the statement we know that the gas is kept at a constant temperature of 0°C, so, if the gas keeps a constant temperature we can use the Boyle's Law to solve this problem.

The Boyle's Law states that:

$P_{1}V_{1}=P_{2}V_{2}$

Where,

P is the pressure of the gas.

V is the volume of the gas.

So, the given information is:

$V_{1}=22.4L\\P_{1}=1atm\\V_{2}=6.2L$

Now, substituting it into the Boyle's Law equation to calculate the new pressure, we have:

$P_{1}V_{1}=P_{2}V_{2}\\\\1atm*22.4L=P_{2}*6.2L\\\\P_{2}=\frac{1atm*22.4L}{6.2L}=3.6atm$

So, the new pressure is 3.6 atm.

Have a nice day!
