The question ask to determine the longest wavelength of radiation that possesses the energy to break the bond and the minimum energy of 242kj/mol is required to break the chlorine-chlorine bond so the energy would be that the minimum wave length is 495nm and the high wavelength to it is the color green end of its wave

Answer:
Answers are given below.
Explanation:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
1) 0.680 moles of H₂S
0.680 mol × 6.022 × 10²³ molecules / 1mol
4.09× 10²³ molecules
2) 8.96 moles of KI
8.96 mol × 6.022 × 10²³ molecules / 1mol
53.96 × 10²³ molecules
3) 6.500 moles of KClO
6.500 mol × 6.022 × 10²³ molecules / 1mol
39.143 × 10²³ molecules
4) 0.950 moles of NaOH
0.950 mol × 6.022 × 10²³ molecules / 1mol
5.721 × 10²³ molecules
5) 4.73 moles of Na₂CO₃
4.73 mol × 6.022 × 10²³ molecules / 1mol
28.48 × 10²³ molecules
Answer:
Using the Guess Method
Explanation:
Finding the square root of a number is an automatic action in tools such as calculator and Excel without any rationale behind it. Hence, I find it more useful to describe as I learned at school: the guess and approach method (it can go by various other names).
The square root of a number is ‘a number which produces a specified quantity when multiplied by itself’.
The Guess Method is guessing that number by approximation until getting exactly the right one.
For example, we want to know the square root of, let’s say, 144. We know that 10*10 is 100. That’s close. Let’s add 1 to that. 11*11 is 121. Getting closer! 12*12 is… 144! Right on! Therefore, the square root of 144 is 12.
I used that technique every time I had to do the math by hand, no matter the number. I thought of a number that could be somewhat close enough (I would guess! Got the method name now? Lol) and adjust until I got my answer right.
Answer:
Explanation:
It’s more difficult to prove a correct theory because theory’s are based off constant trial and error and factual evidence and to disprove a theory it could take one trial to counter argument against a theory
