Answer:
0.1077 grams
Explanation:
First we will employ the ideal gas law to determine the number of moles of nitrogen gas.
PV=nRT
P=2 atm
V=20L
R=0.08206*L*atm*mol^-1*K^-1
T=323.15 K
Thus, 2atm*20L=n*0.08206*L*atm*mol^-1*K^-1*323.15K
K, atm, and L cancels out. Thus n=2*20mol/0.08206*323.15=1.5 moles
Lastly, we must convert the number of moles to grams. This can be done by dividing the number of moles by the molar mass of nitrogen gas, which is 14 grams.
1.5/14=0.1077 grams
Answer:
Electrolysis breaks down water to form hydrogen and oxygen gas : hydrogen + oxygen
Explanation:
Isotopes are always expressed in decimals.
There is 2 atoms in one molecule of sulfuric acid. (Hence the sub-scripted 2 that is next to the H in the sulfuric acid equation)
" n " is called principle quantum number.
Here , n = 2
which means ,
number of shells = 2
.: l ( azimuthal quantum no: ) / ( n - 1 ) = 0 , 1
& m ( magnetic quantum number ) = -1 , 0 , +1 .....
s ( spin quantum number ) = ± 1/2 .....
Coming to this question ,
here n = 2 ....
l = 1 ( possible ) .....
ml = -2 [ not possible , because it can only be a number from this set ( -1 , 0 , +1 ) ] .....
.: this set is not possible
