Based on the information that I know, the correct answer would be visible light. Because, most of the energy from our star the sun, enters in our atmosphere.  The helpful atmosphere blocks gamma rays, then visible light is able to enter, this may have not have sounded smart, but it's correct, your welcome, not trying to be a show off.

Find the ph of a buffer that consists of 0.18 m ch3nh2 and 0.73 m ch3nh3cl (pkb of ch3nh2 = 3.35)?
ozzi
Hello!

First, we need to determine the pKa of the base. It can be found applying the following equation:

pKa=14-pKb=14-3,35=10,65

Now, we can apply the Henderson-Hasselbach's equation in the following way:

pH=pKa+log( \frac{[CH_3NH_2]}{[CH_3NH_3Cl]} )=10,65+log( \frac{0,18M}{0,73M} )=10,04

So, the pH of this buffer solution is 10,04

Have a nice day!

What is the percent of S in
ollegr [7]

The percentage of the sulfur (S) in the compound CuSO₄ is 20.1 %.

<h3>What is the mass percentage?</h3>

The percentage of an element in a compound can be determined as the number of parts by mass of that element present in 100 parts by mass of the given compound.

First, calculate the molecular mass of the given compound by the addition of the atomic masses of all the present elements in the molecular formula. Then, the percentage of the elements can be determined by dividing the total mass of the element by the molar mass of the compound multiplied by 100.

Given, the atomic mass of copper, sulfur, and oxygen is 63.55 g, 32.07 g, and 16.0g respectively.

The molecular mass of CuSO₄ =  63.55 + 32.07 + 4(16.0)  = 159.62 g

The mass percentage of the sulphur = (32.07/159.62) × 100 = 20.1 %

Therefore, the mass percentage of the sulfur is equal to 20.1 %.
