You are performing a titration of a triprotic acid, when you spill water on your lab notebook. you can read that: pka 1 = 1.40,
eimsori [14]
According to the PH formula:
PH= Pka +㏒ [strong base/weak acid]
when we have PH at the first equivalence =3.35 and the Pka1 = 1.4
So, by substitution, we can get the value of ㏒[strong base / weak acid]
3.35 = 1.4 + ㏒[strong base/ weak acid]
∴㏒[strong base/weak acid] = 3.35-1.4 = 1.95 
to get the Pka2 we will substitute with the value of ㏒[strong base/ weak acid] and the value of PH of the second equivalence point
∴Pk2 = PH2 - ㏒[strong base/ weak acid]
          = 7.55 - 1.95 = 5.6

Convert 45.6 milliliters to liters.
KengaRu [80]
To convert milliliters to liters, you should divide the milliliters by 1000. When we do that here, we will see that there are 0.0456 liters in 45.6 milliliters.

The following properties are either physical or chemical. Which one is different from the rest based on those two categories?
inysia [295]

Mass

Explanation:

Mass is different from the rest based on those two categories.

Physical properties are the properties of matter that are usually determined with our senses like taste, feel, color, odor e.t.c

Chemical properties are the properties that relates to a substance when changes are occurring to it.

These properties are boiling point, magnetism and thermal conductivity among others.

Mass is not a physical nor chemical property. It is classified as an extensive property of substances which varies according to the amount of matter it contains.

S + 6 HNO3 →→ H₂SO4 +6 NO₂ + 2 H₂O
bija089 [108]
Start with the 19.7 mol HNO3. use dimensional analysis to correctly convert from mol HNO3 to gram H2O. so, it should look similar to 19.7 mol HNO3 x (2 mol H2O/6 mol HNO3) x (18 g H2O/1 mol H2O)

the first parenthesis’ numbers were received from the balanced equation (for every 6 mol HNO3, 2 mol H2O formed). the second is converting from moles to grams by using the molar mass of H2O (1+1+16). you should get 709.2/6. once you divide those, the answer should be 118.2 g H2O. I’m not sure if your computer requires you to use the exact answer or stop at the correct number of significant digits, but if it does then it might just be 118. g H2O.
