A hypothesis is given to explain a phenomena which has not been explained till then. it can be supported by an experiment if that experiment gets the other results regarding that particular phenomena in agreement with that being predicted by the hypothesis

Well, a hypothesis is " <span>a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation" which would mean you pretty much make an educated guess on what you will think will happen depending on your experiment. So if you guess correctly on what will happen (Example. I think the egg will break, then after you do the experiment the egg does break. This will mean your hypothesis is correct) But if you guess incorrectly this would mean your hypothesis would be incorrect, which I guess would mean if you got it right it would be supporting the hypothesis and if you got it wrong, that would be failing the hypothesis. Then again you should always double check with a parent or guardian because I am not completely sure I read the question correctly. I hope this helps anyways,Good luck!</span>

which of these species is most likely to be a lewis acid and is also least likely to be a bronsted acid
pochemuha

Answer:

This question is incomplete but the completed question is below

Which Of These Species Is Most Likely To Be A Lewis Acid And Is Also Least Likely To Be A Brønsted Acid? (A) NH4⁺ (B) BF₃ (C) H₂O (D) OH⁻

The correct option is B

Explanation:

A lewis acid is a substance that accepts (or is capable of accepting) a pair of electrons. For example BF₃, while a lewis base is a substance that donates (or is capable of donating) a pair of electrons. For example OH⁻.

If we take a look at the boron (B) in BF₃, it has 3 electrons on it's outermost shell, each of which are bonded to flourine and can still accept a pair of electrons (lone pair). <u>This makes it very likely to be a lewis acid</u>.

Bronsted lowry acid is a substance that donates or can donate a proton or H⁺ (for example HCl) while bronsted lowry base is a substance that accepts or can accept a proton or H⁺ (for example NH₃).

<u>BF₃ cannot donate a proton or H⁺ hence it is least likely to be called a bronsted acid.</u>

What are the charges of families 1, 2, &amp; 13 (boron family) if/when they become Ions
Natalka [10]

Answer:

Explanation:

Group one elements are alkali metals. All alkali metal have one valance electron. They loses their one valance electron and from cation with charge of +1.

Charges on group one.

Hydrogen = +1

Lithium = +1

Sodium = +1

Potassium = +1

Rubidium = +1

Cesium = +1

Francium = +1

Group two elements are alkaline earth metals. All alkaline earth metal have two valance electron. They loses their two valance electron and from cation with charge of +2.

Charges on group two.

Beryllium = +2

Magnesium = +2

Calcium = +2

Strontium = +2

Barium= +2

Radium = +2

Group 13 elements are boron family. All elements have three valance electrons. They loses their three valance electron and from cation with charge of +3.

Charges on group 13.

Boron = +3

Aluminium = +3

Gallium = +3

Indium = +3

Thallium= +3

Group 13 elements are also shows +1 charge by losing one valance electron.

According to the quantum-mechanical model for the hydrogen atom, which electron transition produces light with the longer wavele
LekaFEV [45]

Answer:

Explanation:

The main task here is that there are some missing gaps in the above question that needs to be filled with the appropriate answers. So, we are just going to do rewrite the answer below as we indicate the missing gaps by underlining them and making them in bold format.

SO; In the quantum-mechanical model of the hydrogen atom.

As the n level increases. the energy <u>increases</u> and thus levels are <u>closer to </u>each other. Therefore, the transition <u>3p→2s</u> would have a greater energy difference than the transition from <u>4p→3p.</u>

Energy \  and \  wavelength  \ are \  inversely \   proportional , \  so \  the \ \mathbf{ 4p\to 3p} \ transition  \ wouldproduce  \ a  \ longer \ wavelength.
