Energy levels inside an atom are the specific energies that electrons can have when occupying specific orbitals.
Answer:
9 atoms
Explanation:
Explanation: In 1 formula unit of Al(NO3)3 , there are (clearly!) 9 atoms of oxygen, 3 nitrogen atoms, and 1 aluminum atom. I have gone on before that the mole ( NA , Avogadro's number) is simply a much larger number, i.e. NA = 6.022×1023 .
Answer:
0.93956kg
Explanation:
Equation for the reaction is given as;
P4 + 5O2 --> P4O10
From the equation, 1 mole of P4 produces 1 mole of P4O10.
Mass = Number of moles * molar mass
Mass of P4 = 1 mol * 123.88 g/mol = 123.88 grams
Mass of P410 = 1 mol * 283.886 g/mol = 283.886 g
This means 123.88 grams of P4 produced 283.886 g of P4O10.
How many kilograms of P4O10 would be produced from 410. g of pure P4 ?
123.88 = 283.886
410 = x
x = (410 * 283.886 ) / 123.88
x = 939.56g
Upon converting to Kilogram by dividing by 1000
x = 0.93956kg
<u>Answer:</u> The solubility of chromium (III) iodate is 
<u>Explanation:</u>
Solubility product is defined as the product of concentration of ions present in a solution each raised to the power its stoichiometric ratio.
The chemical equation for the ionization of chromium (III) iodate follows:
s 3s
The expression of 
for above equation follows:
We are given:
Putting values in above expression, we get:
Hence, the solubility of chromium (III) iodate is
