Q. 8 normally, the ph of the human body is fixed in a very narrow range between 7.35 and 7.45. a
patient with an acidotic blood ph of 7.3 may be treated with an alkali such as sodium bicarbonate.
why would this treatment raise the ph of the blood? can you explain it?

Correct answer is( respiratory alkalosis) is a primary decrease in  pco2 with or without compensatory decrease  in h2o3 

True, the standard unit for volume is liters which can be represented by either a lower case "l" or a capital "l"

The problem here is that according to aufbau principle before 3d orbital 4s subshell comes.after filling 3p orbital with electrons you have 4 electrons left, you place two in 4s with opposite spin and the other two in 3d in any of its two orbitals of total five orbitals with the same spin.
