Concept explainers
(a)
Interpretation: The total volume of water that needs to be processes for the production of 45 L pure water needs to be determined.
Concept Introduction:The excess pressure applied to a solution in order to prevent the passage of solvent to the solution is said to be osmotic pressure. The formula to determine the osmotic pressure, π is:
π = iMRT - (1)
Where i is van’t Hoff’s factor, M is molar concentration, R is ideal gas constant and T is temperature in K.
(b)
Interpretation: Whether the same system will work for purifying sea water, 0.60 M NaCl or not should be determined.

- please solve this, and help me know which boxes to check. Thank you so much in advance.arrow_forwardElectronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. Describe how electronegativity is illustrated on the periodic table including trends between groups and periods and significance of atom size.arrow_forwardDefine the term “transition.” How does this definition apply to the transition metals?arrow_forward
- Describe how the properties of the different types of elements (metals, nonmetals, metalloids) differ.arrow_forwardUse a textbook or other valid source to research the physical and chemical properties of each element listed in Data Table 1 using the following as a guideline: Ductile (able to be deformed without losing toughness) and malleable (able to be hammered or pressed permanently out of shape without breaking or cracking) or not ductile or malleable Good, semi, or poor conductors of electricity and heat High or low melting and boiling points Occur or do not occur uncombined/freely in nature High, intermediate, or low reactivity Loses or gains electrons during reactions or is not reactivearrow_forwardProvide the Physical and Chemical Properties of Elements of the following elements listedarrow_forward
- Questions 4 and 5arrow_forwardFor a titration of 40.00 mL of 0.0500 M oxalic acid H2C2O4 with 0.1000 M KOH, calculate the pH at each of the following volume of KOH used in the titration: 1) before the titration begin;2) 15 mL; 3) 20 mL; 4) 25 mL; 5) 40 mL; 6) 50 mL. Ka1 = 5.90×10^-2, Ka2 = 6.50×10^-5 for oxalic acid.arrow_forwardPredict the major organic product(s), if any, of the following reactions.
