Use the scenario to answer the following question. Four scientists observed an area of land that had been cleared of all trees a

nd bushes to make space for a power line. Each scientist had a different argument about the impact clearing this area of land might have on the bird population living in the ecosystem. Which scientist’s argument demonstrates how the ecosystem will MOST LIKELY be impacted? A. Scientist 4: The rate of erosion will decrease causing less food and shelter to be available to the birds. B. Scientist 1: The natural enemies of birds will be eliminated causing less food and shelter to be available to the birds. C. Scientist 2: Weather conditions may change causing less food and shelter to be available to the birds. D. Scientist 3: The population of trees in the environment will decrease causing less food and shelter to be available to the birds.

Which of the following statements about 13C NMR is not true?A. In 13C proton-decoupled NMR spectra, all peaks are singlets.B. 13
adoni [48]

Answer: .B. 13C NMR spectra display peaks for only carbons that bear hydrogen atoms.

Explanation:

The statements that are true about 13C NMR are:

A. In 13C proton-decoupled NMR spectra, all peaks are singlets.

C 13C NMR chemical shifts occur over a greater range than 1H NMR chemical shifts.

D. 13C NMR easily differentiates between the different hybridized carbons (sp3, sp2, and sp hybridized carbons).organic-chemistry

Therefore, the option that isn't true is option B. "13C NMR spectra display peaks for only carbons that bear hydrogen atoms". This is false because 13C NMR will show every peak in the spectrum and it doesn't matter if it's only carbons that bear hydrogen atoms as everything will be shown.

If 0.089 grams of KI is dissolved in 500g of H2O, what is the concentration of the resulting solution in parts per million?
frez [133]

Answer:

The concentration of the resulting solution in parts per million is 177.97

Explanation:

Parts per million (ppm), is a unit of measure for concentration that refers to the number of units of the substance per million units of the set.

The concentration in parts per million expressed in mass / mass is calculated by dividing the mass of the solute (ms) by the mass of the solution (md, sum of the mass of the solute and the mass of the solvent), both expressed in the same unit and multiplied by 10⁶ (1 million).

ppm=\frac{ms}{md} *10^{6}

So, being:

  • ms: 0.089 grams of KI
  • md: 0.089 grams of KI + 500 grams of H₂O= 500.089 grams

Replacing:

ppm=\frac{0.089 grams}{500.089 grams}*10^{6}

ppm= 177.97

<u><em>The concentration of the resulting solution in parts per million is 177.97</em></u>
