Answer:
Yes. Example: <u>Sulfur hexafluoride (SF₆) molecule</u>
Explanation:
According to the octet rule, elements tend to form chemical bonds in order to have <u>8 electrons in their valence shell</u> and gain the stable s²p⁶ electronic configuration.
However, this rule is generally followed by main group elements only.
Exception: <u>SF₆ molecule</u>
In this molecule, six fluorine atoms are attached to the central sulfur atom by single covalent bonds.
<u>Each fluorine atom has 8 electrons in their valence shells</u>. Thus, it <u>follows the octet rule.</u>
Whereas, there are <u>12 electrons around the central sulfur atom</u> in the SF₆ molecule. Therefore, <u>sulfur does not follow the octet rule.</u>
<u>Therefore, the SF₆ molecule is known as a </u><u>hypervalent molecule</u><u> or expanded-valence molecule.</u>
Electromagnetic energy would be your answer :)
The answer to your proposed question is Neutron. This is because the atomic mass unit of a neutron is 1 and so it would contribute to the overall mass of the atom.
I hope this answer helped you!
Answer: The sodium peroxide needed per sailor in a 24 hr period is 674 grams.
Explanation:
According to ideal gas equation:
P = pressure of gas = 1.02 atm
V = Volume of gas = 150.0 ml = 0.15 L
n = number of moles of carbon dioxide = ?
R = gas constant =
T =temperature =
According to stoichiometry:
2 moles of carbon dioxide require = 2 moles of sodium peroxide
Thus 0.006 moles carbon dioxide require= 
moles of sodium peroxide
Mass of sodium peroxide needed for 24 hour=
Thus sodium peroxide needed per sailor in a 24 hr period is 674 grams.
Answer:
I don't even know I'm sorry
