Answer: D NH3

Explanation:When NH3 , popularly called ammonia react with water, the water molecules dissociate into it's components H^+ and OH^-,the H^+ which is the cation forms an hydrogen bond with ammonia NH3 to form NH4^+ while the anion form is OH^-.the reaction itself is a dipolar reaction .

NH3 + H2O_____NH4^+ +OH^-

A container of gas has a volume of 3.5 L and a pressure of 0.8 atm. Assuming the temperature remains constant, what volume of ga
vovikov84 [41]
<h3>Answer:</h3>

5.6 L

<h3>Explanation:</h3>

We are given;

  • Initial volume, V1 = 3.5 L
  • Initial pressure, P1 = 0.8 atm
  • Final pressure, P2 = 0.5 atm

We are required to calculate the final volume;

  • According to Boyle's law, the volume of a fixed mass of a gas and the pressure are inversely proportional at a constant temperature.
  • That is; P α 1/V
  • Mathematically, P=k/V
  • At two different pressure and volume;

           P1V1 = P2V2

In this case;

Rearranging the formula;

V2 = P1V1 ÷ P2

     = (0.8 atm × 3.5 L) ÷ 0.5 atm

    = 5.6 L

Therefore, the resulting volume is 5.6 L

The line graph shows the heights of plants grown in fertilized and unfertilized soil. Based on this information, what will most
Helen [10]

Answer:

  • <u><em>g) Neither plant should increase by 1 cm in height.</em></u>

Explanation:

See the graph for this question on the figure attached.

The growing of the <em>plant A</em> is represented by the line that goes above the other. At start, that line has a slope that rises about 0.75 cm ( height increase) in 1 day. From the day 2 and forward the slope of the line decreases. The line reaches its highest point about at day 4 and seems to start decreasing. Thus, you should predict that on the day six it <em>most likely </em>does not increase in height.

The growing of the <em>plant B</em> is represented by the line drawn below the other. As for the plant B, the growing decreases with the number of days. Between the days 4 and 5 the line is almost flat, which means that <em>most likely</em> this plant will not grow on the day six or grow less than 0.5 cm.

Thus, for both plants you can say that <em>on day six, most likley, neither should increase by 1 cm in height (</em>option g).
