A scientist studies the growth of plants in a laboratory. Which experimental procedure would provide evidence that
dusya [7]

The experimental procedure would provide evidence that plants need

nitrogen to grow is by

  • Identical plants are placed in two air-tight containers with sufficient exposure to sunlight.
  • One container has nitrogen gas, and the other has room air. The scientist measures plant growth

It is necessary to use identical plants during the experiment as plants have

different rates of nitrogen absorption from the soil. It should also be done in

air-tight containers called terrariums to prevent loss or contamination of the

gases with other elements/compounds.

The identical plants containing nitrogen and room air should both be

measured for the growth difference between them.

A certain alcohol contains only three elements, carbon, hydrogen, and oxygen. Combustion of a 20.00 gram sample of the alcohol p
bagirrra123 [75]

The empirical formula is C₂H₆O.

We must calculate the <em>masses of C, H, and O</em> from the masses given.

<em>Mass of C</em> =38.20 g CO₂ × (12.01 g C/44.01 g CO₂) = 10.424 g C

<em>Mass of H</em> = 23.48 g H₂O × (2.016 g H/18.02 g H₂O) = 2.6268 g H

<em>Mass of O</em> = Mass of compound - Mass of C - Mass of H

= (20.00 – 10.424 – 2.6268) g = 6.9487 g

Now, we must <em>convert these masses to moles</em> and <em>find their ratios</em>.

From here on, I like to summarize the calculations in a table.

<u>Element</u>  <u>Mass/g</u>    <u>Moles</u>    <u>Ratio</u>  <u>Integers</u>  

     C        10.424    0.8680  1.999        2

     H         2.6268  2.606    6.001        6

     O        6.9487  0.4343    1                1

The empirical formula is C₂H₆O.
