Answer/Explanation:
Heat from the sun hits the ground and is absorbed. The higher you go, it gets more colder due to the fact that the air doesn't hold onto the radiation as it goes straight through the ground, which is why the top of mountains are very cold, and people are able to die in minutes.
When the concentration is expressed in mass percentage, that means there is 3 g of solvent H₂O₂ in 100 grams of the solution. Then, that means the remaining amount of solute is 97 g. We use the value of molarity (moles/liters) to determine the amount of solution in liters, denoted as V. The solution is as follows:
0.02 mol KMnO4/L solution * 158.034 g KMnO4/mol * V = 97 g KMnO4
Solving for V,
V = 30.69 L
Answer: Yes the absorb in the visible range.
Explanation:
The relationship between wavelength and energy of the wave follows the equation:
where,
= energy of the wave = 182 kJ/mol = 182000 J/mol
N = avogadro's number = 
h = plank constant = 
c = speed of light = 
= wavelength of the wave = ?
Putting all the values:
The wavelength range for visible rays is 400 nm to 750 nm, thus the complex absorb in the visible range.
The answer is 1815.15 mm hg
Answer : The mass of 
dissolved will be, 0.2365 grams
Explanation :
First we have to calculate the concentration of .
As we know that,
where,
= concentration of = ?
= partial pressure of = 1.65 atm
= Henry's law constant = 
Now put all the given values in the above formula, we get:
The concentration of = 
Now we have to calculate the moles of
Now we have to calculate the mass of
Therefore, the mass of dissolved will be, 0.2365 grams
