which is stronger, ionic bonding or covalent bonding? and why

Answers

I think so the answer would be Ionic Bonding

Im not sure

Answer:

ionic bonding because of the coulombic attraction between ions of opposite charges. 

For the following element, predict the most likely oxidation number (charge) for its corresponding ion.

Aluminum

A. Al+3
B. Al+1
C. Al-3
D. Al-1

Answers

Answer: A. Al+3

Explanation:

The most likely ion of Aluminum is Al³⁺ (group 3A) since losing three electrons is the most energetically favorable way for it to follow the octet rule.

Because the charge on ions is equivalent to their oxidation state, then +3 is the most likely oxidation number of Aluminum.

The photoelectron spectrum for the element nitrogen is represented above. Which of the following best explains how the spectrum is consistent with the electron shell model of the ato
f the atom?
A. The leftmost peak represents the valence electrons.

B. The two peaks at the right represent a total of three electrons.

C. The electrons in the ls sublevel have the smallest binding energy

D. The electrons in the 2p sublevel have the smallest binding energy

Answers

Answer:

D. Is the correct option.

Explanation:

2p level contains the electrons furthest from the nucleus in the case of Nitrogen thus it's much easier to disperse/remove the electrons from the shell due to low pull of nucleus energy.

The best explanation of how the spectrum is consistent with the electron shell model of the atom is the electrons in the 2p sub level have the smallest binding energy. Thus, option D is correct.

What is photoelectron spectrum?

Photoemission spectroscopy also known as photoelectron spectroscopy which photoelectric effect is the process in which electron are get energy from external source of energy like sunlight deals with energy measurement of energy emission or electrons emitted from solids, gases or liquids by the process of photoelectric effect,

Photoelectric effect is the process in which electron are get energy from external source of energy like sunlight and get excited and comes in excited state from the ground state due to this process continuos  flow of electron is take place and after that flow of energy is takes place.

Therefore,The best explanation of how the spectrum is consistent with the electron shell model of the atom is the electrons in the 2p sub level have the smallest binding energy. Thus, option D is correct.

What is the molarity of 930 mL of LiCl solution that contains 139.9 g of LiCI?
A. 3.5 mol/L
B. 150 mol/L
C. 3.3 mol/L
D. 3.5 x 10-3 mol/L

Answers

Answer:  A) 3.5 mol/L

Explanation:

To determine the molarity, we have to find the number of moles in the volume given, and then extrapolate to find the number of moles that would be in 1 L.

Determine the moles in the given volume

moles of LiCl = mass ÷ molar mass

                       = 139.9 g ÷ 42.39 g/mol

                       = 3.30 mol

Find the moles in 1 L

    Since 930 mL of LiCl    =   3.30 mol

    then 1000 mL of LiCl    =   (3.30 mol × 1000 mL/L) ÷ 930 mL

                                           =  3.55 mol/L
