Explanation:
Nitrogen dioxide is one of the primary components of air pollution. It is released by the combustion of nitrogen oxide.
<h3 /><h3>How do you calculate the percentage yield of nitrogen oxide?</h3>
Given:
- Mass of nitrogen oxide consumed = 1500 kg
- Mass of nitrogen oxide produced = 1500 kg
The given chemical equation of nitrogen oxide is:
Now, to calculate the percentage yield, the following conversion factor should be used:
Nitrogen dioxide = 2300 kg
The percentage yield will be:
Percentage yield = 65.2 %
Thus, the percentage yield of nitrogen dioxide is 65.2%.

Answer:
2HClO4 + Ca(OH)2 = Ca(ClO4)2 + 2H2O
Explanation:
Formula for aqueous perchloric acid is; HClO_4 (aq)
Formula for aqueous calcium hydroxide is; Ca(OH)_2 (aq)
Thus chemical equation is;
HClO4 + Ca(OH)2 = Ca(ClO4)2 + H2O
We have to balance it and so we now have;
2HClO4 + Ca(OH)2 = Ca(ClO4)2 + 2H2O
Answer:
D. Phototropism
Explanation:
Plants, like every other living organism, responds to external stimulus. In this question, the stimulus is LIGHT from the sun entering through the window sill. The plant is responding positively to the light stimuli by growing towards the direction where the light is coming from. This exhibit is called PHOTOTROPISM.
Phototropism, comes from two words viz photo- meaning light and tropism- meaning movement. Hence, phototropism is the growth of an organism (plant in this case) in response to a light stimulus. The case described in this question is POSITIVE PHOTOTROPISM because the growth occurs towards the light source.
