What you have to keep in mind is that
pH = - log[H+]
so 3.75 = -log[H+], we get [H+]=
,
that is [H+]≈1.77827941×
(i see this result on calculator)
this is just what you want!
Answer:
The three methods we can use to separate a mixture are:
1.sublimation
example: sand and camphor
2.centrifugation
example:cream from milk
3.evaporation
example:salt from sea water
PH and pOH are opposites, so pH can be determined by subtracting pOH from 14
pH = 14 - 7.9 = 6.1
The polar molecules dissolve in water, because water is also a polar molecule.
"Like dissolves like".

Answer:
Explanation:
Example #1: How many moles of oxygen will occupy a volume of 2.50 L at STP? Standard ... What is the volume of gas at 2.00 atm and 200.0 K if its original volume was ... P2 = 2.00 atm 2.000tm) 273k. T=273k. 200.0k. Tz= 200.0k. V, = 200.0L ... A gas has a pressure of 0.370 atm at 50.0°C. What is the pressure at standard.
