Answer:
No. If you were to set up what the friend said it would look like this:
19.7g × 
==> 
×
The above does not look right because the grams do not cancel out. If it's not cancelled, it would be included in your final answer, but you're looking for moles not grams.
When setting up a stoichiometry equation, you have to put the same unit of measurement (ex- grams, cm, mm, etc.) on the numerator of one side and the denominator of the other side.
This would cancel out the unit.
For example: If you wanted to find out how much of 320 cm are in a meter.
*there are 100 cm in 1 meter*
(1. always start with the given number!)
(2. set up the next fraction where you can cancel out cm)
× 
= 3.2 m
Going back, your friend would have to switch the units from grams/moles to moles/grams. It would cancel out grams, which would leave moles. Therefore, moles will be included in your final answer.
× 
= _?_ moles
a] work out mass of 1 mole P4S3 -- call this Y grams
b] eqtn tells you 1 mole P4S3 gives 3 moles SO2 [= 3 x 22.4L at STP]
c] by simple proportion
1g P4S3 gives (3 x 22.4)/Y SO2 at STP answer
I believe the anwser is C
I hope this is right! <3
L = an integer from 0 to n-1
<span>mL = an integer from -L to +L </span>
<span>ms = + or - 1/2 </span>
<span>the format is (n, L, mL, ms) </span>
<span>so your </span>
<span>n = 3... this is OK </span>
<span>L = 2.. also OK.. if n=3, L can = 0, 1, or 2 </span>
<span>mL = -3 is NOT ok... if L=2.. mL can only be -2, -1, 0, +1, or +2 </span>
<span>ms = +1/2 and that is ok
Hope this helps!</span>
Answer:
Fluid Friction
Explanation:
Fluid friction involves a fluid or air. The air resistance on an airplane or water resistance on a boat is fluid friction. Rolling Friction - Rolling friction occurs when a round surface rolls over a surface, like a ball or wheel.
