Answer to Problem 1RQ

Solution:

The main disadvantage of soap is that it does not work well in hard water and the main advantage of soap is that it is derived from renewable sources.

Explanation of Solution

Advantages of soap:

  1. It is an excellent cleanser in soft water.
  2. It is relatively non-toxic.
  3. It is derived from renewable sources (animal fats and vegetable oils).
  4. It is biodegradable.

Disadvantages of soap:

  1. It does not work well in hard water as hard water contains calcium, magnesium and iron ions. The anions of soap react with the metal ions and form insoluble, greasy curds.
  2. In acidic solutions, soaps are converted to free fatty acids, which have no cleansing action and are also insoluble in water and separate as a greasy scum.
Conclusion

The main disadvantage of soap is that it does not work well in hard water and the main advantage of soap is that it is derived from renewable sources.

The emission data in cps displayed in Table 1 is reported to two decimal places by the chemist. However, the instrument output is shown in Table 2. Table 2. Iron emission from ICP-AES Sample Blank Standard Emission, cps 579.503252562 9308340.13122 Unknown Sample 343.232365741 Did the chemist make the correct choice in how they choose to display the data up in Table 1? Choose the best explanation from the choices below. No. Since the instrument calculates 12 digits for all values, they should all be kept and not truncated. Doing so would eliminate significant information. No. Since the instrument calculates 5 decimal places for the standard, all of the values should be limited to the same number. The other decimal places are not significant for the blank and unknown sample. Yes. The way Saman made the standards was limited by the 250-mL volumetric flask. This glassware can report values to 2 decimal places, and this establishes our number of significant figures. Yes. Instrumental data…
