I’m not sure how to show the work
You should download the app chem balance
It’s great for this kind of homework
Answer:
6.023*10 ²³ molecules
Explanation:
Moles is denoted by given mass divided by the molecular mass ,
Hence ,
n = w / m
n = moles ,
w = given mass ,
m = molecular mass .
From the question ,
given mass of NaCl = w = 58.5 g
As we know the molecular mass of NaCl = m = 58.5 g/mol
Moles can be calculted from the above formula -
n = w / m = 58.5 g / 58.5 g/mol = 1 mol
Since , 1 mol has 6.023*10 ²³ particles ,
Therefore ,
1 mol of NaCl = 6.023*10 ²³ molecules
I would think it would be D because if the velocity can change and if that changes then its either acceleration or deceleration. depends on how it changes.
I hope that helps! :)
Answer:
l=1
Explanation:
The angular momentum quantum number is a quantum number that describes the 'shape' of an orbital and tells us which subshells are present in the principal shell. A critical look at the electronic configuration of phosphorus at the ground state depicts the outermost electron to be in the P orbital where the angular quantum number ,l=1 .
