Explanation:
What Adi failed to realize is that the oily substance that was obtained from lavender consists of a mixture of substances. It is not only the required fragrance that is present in the extract.
This experiment will not work because those other components in the mixture may be erroneously identified when they show up in the mass spectrum of the extract and may be mistaken for the fragrance in question.
Hence the experiment will not work because; if some kind of separation method is not used to identify other impurities in the oil, many other substances may be mistaken for the actual fragrance.
Answer:
They have the same number of valence electrons (5) so the body assumes they are the same element.
Answer:
1 ethanol is right answer
Explanation:
CH3- CH2-OH
I think the answer to that is B
<u>Answer:</u> The concentration of
ions are 2.797 ppm and 0.212 ppm respectively.
<u>Explanation:</u>
To calculate the mass of solution, we use the equation:

Volume of gold = 100 L = 100000 mL (Conversion factor: 1 L = 1000 mL)
Density of gold = 1.001 g/mL
Putting values in above equation, we get:

To calculate the concentration in ppm (by mass), we use the equation:

- <u>Calculating the concentration of calcium ions:</u>
Mass of
ions = 0.280 g
Putting values in above equation, we get:

- <u>Calculating the concentration of magnesium ions:</u>
Mass of
ions = 0.0220 g
Putting values in above equation, we get:

Hence, the concentration of
ions are 2.797 ppm and 0.212 ppm respectively.
