Answer:

0.077M is the concentration of the hydroxyl ion

Explanation:

Dilution factor is the ratio between the aliquot that is taken of a solution and the total volume of the diluted solution.

For the problem, dilution factor is:

7.53cm³ / 147cm³ =<em> 0.05122</em>

To obtain molarity of a diluted solution you must multiply dilution factor and initial molarity of the solution, thus:

1.5 M × 0.05122 = <em>0.077M is the concentration of the hydroxyl ion</em>

A sample of helium gas occupies 355ml at 23°c. if the container the he is in is expanded to 1.50 l at constant pressure, what is
ss7ja [257]

Answer: The final temperature would be 1250.7 K.

Explanation: We are given a sample of helium gas, the initial conditions are:

V_{initial}=355mL=0.355L  (Conversion factor: 1L = 1000 mL)

T_{initial}=23\°C=296K (Conversion Factor: 1° C = 273 K)

The same gas is expanded at constant pressure, so the final conditions are:

V_{initial}=1.50L

T_{initial}=?K

To calculate the final temperature, we use Charles law, which states that the volume of the gas is directly proportional to the temperature at constant pressure.

V\propto T

\frac{V_{initial}}{T_{initial}}=\frac{V_{final}}{T_{final}}

Putting the values, in above equation, we get:

\frac{0.355L}{296K}=\frac{1.50L}{T_{final}}

T_f=1250.7K

10) The presence of nitrates in soil can be shown by warming the soil with
tresset_1 [31]

Answer:

ammonia

Explanation:

Nitrogen fertilizers contain N in the forms of ammonium, nitrate and urea. Upon application to the soil, urea-N rapidly hydrolyzes to ammonia, thus it shares similar characteristics as ammonia-based N fertilizers.
