It will be D because it is always good practice to take more than five recordings/results/observations so that if you realize that the results vary a bit, you can find the average.

Explain why it is harder to remove an inner shell electrons than a valence electron from an atom
VMariaS [17]
<span> It makes sense that an inner shell electron would be tougher to remove than a valence electron because the inner shell electron is closer to the positive nucleus of the atom. Seeing as an electron caries a negative charge it would be too attracted to the positive core to leave readily. Also, the inner shell electrons are constantly repelling electrons outside of it's energy level (however the reason these electrons outside innershell energy levels don't simply fly away is the charge of the positive core overcomes the smaller charges of the comparably negligible inner shell electrons, but that repulsion is still there so keep that in mind) </span>

If 1.320 moles of CH4 reacts completely with oxygen, how many grams of H2O can be formed
Rainbow [258]

Answer:

47.5 g of water can be formed

Explanation:

This is the reaction:

CH₄  +  2O₂  →  CO₂ + 2H₂O

Methane combustion.

In this process 1 mol of methane react with 2 moles of oxygen to produce 2 moles of water and 1 mol of carbon dioxide.

As ratio is 1:2, I will produce the double of moles of water, with the moles of methane I have.

1.320 mol  .2 = 2.64 moles

Now, we can convert the moles to mass (mol . molar mass)

2.64 mol . 18g/mol = 47.5 g

We have learned that the Lewis model portrays a chemical bond as the transfer or sharing of electrons represented as dots. Valen
photoshop1234 [79]

Answer:

According to molecular orbital theory, chemical bond occurs as electrons are able to reduce their energy by entering the resulting molecular orbitals.

Chemical bonds are not located among atoms, they are distributed all over the molecule.

Uses test methods to solve the equation of Schrodinger.

You can never do better than nature, however strong your assumption is. Calculations of minimum energy must be done by software.
