Answer:
I think 767.8
Explanation:
I first did 10 times 22 bc that little carrot sign means squared so I did 10 times 22 and that equaled 220, then I did 3.49 times 220 and that is the answer which is 767.8
Answer:
d. ns2np3
Explanation:
In the first main group all elements have a singly occupied s orbital.
In the second main group, all elements have a doubly occupied s orbital.
In the third main group or 13th group all elements have a doubly occupied s orbital and a singly occupied p orbital.
In the fourth main group or 14th group all elements have a doubly occupied s orbital and a doubly occupied p orbital.
In the fifth main group or 15th group all elements have a doubly occupied s orbital and a triply occupied p orbital.
And so on.
Answer:
gamma rays have a different wavelength then light waves (visible waves excluding ultraviolet) gamma rays are released from radioactive substances along with alpha and beta particles.
Explanation:
Gama rays are a separate wavelength their are many different wavelengths look up a spectrum chart on the internet to better understand.
mass O₂ required : 0.054 g

Further explanation
</h3>
The reaction equation is the chemical formula of reagents and product substances
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products
Reaction
4Fe(OH)⁺ (aq) + 4OH⁻ (aq) + O₂ (g)+ 2H₂O (l)⇒ 4Fe(OH)₃ (s)
To precipitate Fe²⁺(in Fe(OH⁺) to Fe³⁺(in Fe(OH)₃)
mol ratio from equation = mol O₂ :mol Fe(OH) = 1 : 4
As we know that the equivalency point of moles of added base will be equal to the moles of original acid, this allows to determine the number of moles of original acid.
<h3>
How do you find the concentration at the first equivalence point?</h3>
At the equivalency point the moles of added base will be equal to the moles of original acid, this allows the determination of the number of moles of original acid. This can be combined with the original volume of the analyte solution in order to determine its concentration.
So we can conclude that at the equivalence point the moles of added base will be equal to the moles of original acid, this allows the determination of the number of moles of original acid.
