Answer:

For the tetrahedral case the repulsion is smaller.

Explanation:

It is smaller for the tetrahedral case because he angles for tetrahedral molecules are greater (109.5) then for octahedral molecules (90). The greater the distance between the atoms the smaller the repulsion, and so the bigger are angles the bigger is distance.

Which of the following weak interactions would require the least amount of energy to disrupt? Group of answer choices
SpyIntel [72]

Answer: Option (c) is the correct answer.

Explanation:

A hydrogen bond is defined as a weak bond that is formed between an electropositive atom (generally hydrogen atom) and an electronegative atom like oxygen, nitrogen and fluorine.

An ionic bond is defined as a bond formed between a metal and a non-metal and in this bond transfer of electron takes place from metal to non-metal. And, due to the presence of opposite charges on the combining atoms there exists a strong force of attraction.

Vander waal forces are defined as the weak electric forces which tend to attract neutral molecules towards each other in gases, liquefied and solidified gases.

Vander waal forces are very weak forces.

Thus, we can conclude that Van der walas interactions are weak interactions would require the least amount of energy to disrupt.

Please help<br><br><br> How many moles are there in 7.57 x 10^30 molecules of CO2?
Oxana [17]

Answer:

The answer is

<h2>12,574,750.83 moles</h2>

Explanation:

In order to find the moles of CO2 we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question

N = 7.57 × 10^30 molecules of CO2

We have

n =  \frac{7.57 \times  {10}^{30} }{6.02 \times  {10}^{23} }  \\  = 12574750.83056...

We have the final answer as

<h3>12,574,750.83 moles</h3>

Hope this helps you
