Answer:

The answer to your question is  Al, Mg, Si, S, P

Explanation:

First ionization energy is the energy necessary to remove an electron from an atom in a gaseous form.

Element           First ionization energy (kJ/mol)

Magnesium              737.7  

Aluminum                 577.5

Silicium                    786.5

Phosphorus              1011.8

Sulfur                        999.6

Order:   Al, Mg, Si, S, P

Calcium forms ions with a charge of +2. Iodine forms ions with a charge of -1. Which of the following would represent an ionic c
Stolb23 [73]
Well you know that you have to balance out the equation to 0. So if I is -1 and Ca is +2 you know that I had to equal to -2. So you can do that by having two of them. So Ca=+2 and I2=-2 so CaI2 would equal 0 meaning that would be the correct answer. Hope that I explained that correct :)

Which of the following molecules would be the best hydrogen bond donor?
leva [86]

Answer: Option (d) is the correct answer.

Explanation:

When a hydrogen atom comes in contact with an electronegative atom then it results in the formation of a chemical bond.

More is the electronegativity of combining atom, more stronger will be the bond with hydrogen atom. As a result, the compound formed will not easily give up hydrogen atom upon dissociation.

Whereas less is the electronegativity of atom combining with hydrogen atom, easily it will donate the hydrogen atom upon dissociation.

Since, out of the given option sulfur (S) atom has low electronegativity as compared to oxygen and nitrogen atom.

Hence, CH_{3}SH will easily donate hydrogen atom.

Thus, we can conclude that CH_{3}SH molecule would be the best hydrogen bond donor.

What are some of the techniques by which mixtures can be resolved into their components?
shtirl [24]
<span>Distillation, filtration, evaporation are some of the techniques by which mixtures can be resolved into their components.Distillation is the process of separating the component or substances from a liquid mixture by selective evaporation and condensation.Filtration is any of various mechanical, physical or biological operations that separate solids from fluids (liquids or gases) by adding a medium through which only the fluid can pass.Evaporation is a type of vaporization of a liquid that occurs from the surface of a liquid into a gaseous phase that is not saturated with the evaporating substance.</span>
