Answer:
Oxygen molecule is 2 oxygen atoms in a covalent bond, whereas an oxygen atom is an atom with 8 electrons (6 valence electrons).
Thus, clearly, any element in a bonded state is always more stable than when in an un-bonded state.
Explanation:
Answer: 0.37g
Explanation:avogadro number = 6.02214076x10^23 atoms/molecules per mole
a mole of Na2O = 2*23 + 16 = 52 g
4.25x10^21 atoms = 52*(4.25*10^21/6.02214076*10^23) = 0.37 g
Answer:
M = 3.69 M.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the molar concentration of the 1.29 moles of KCl in 350 mL of solution by recalling the mathematical definition of molarity as the division of the moles by the volume in liters, in this case 0.350 L; thus, we proceed as follows:
Which gives molar units, M, or just mol/L.

Hello, to answer your question fully.
<span>D. Make all the hamsters run on a hamster wheel for the same amount of time.
Because your doing the experiment on exercise not anything else
so keeping charts in a notebook and set a time on how long they were on it and how long you want them to be on it.

In the categorization of tornadoes, most tornadoes (87%) are no stronger than EF1 unless 'most' is considered 55% in which case the answer is EF0.
EF0 - 65 to 85 mph {104.61 to 136.79 km/h}EF1 - 86 to 110 mph {138.40 km/h to 177 km/h}
Hence the answer would have to be C
