Answer:
(a) The rate of formation of K2O is 0.12 M/s.
The rate of formation of N2 is also 0.12 M/s
(b) The rate of decomposition of KNO3 is 0.24 M/s
Explanation:
(a) From the equation of reaction, the mole ratio of K2O to O2 is 2:5.
Rate of formation of O2 is 0.3 M/s
Therefore, rate of formation of K2O = (2×0.3/5) = 0.12 M/s
Also from the equation of reaction, mole ratio of N2 to O2 is 2:5.
Rate of formation of N2 = (2×0.3/5) = 0.12 M/s
(b) From the equation of reaction, mole ratio of KNO3 to O2 is 4:5.
Therefore, rate of decomposition of KNO3 = (4×0.3/5) = 0.24 M/s
Answer:
Percentage Yield is calculated by doing -> experimental/theoretical x 100% = percentage yield.
I THINK that if your questions are connected it should be 14/16.89 x 100% = 82.889%
Explanation:
Carbon because it is not stable
The industrial process that utilizes that strategy of evaporation to separate a solution is known as Distillation.
<h3>What is Evaporation?</h3>
Evaporation may be defined as the methodology of liquid transforming into vapors even below its boiling point.
Distillation is an influential technique to isolate mixtures that are constituted of two or more refined liquids.
Distillation is a purification procedure where the elements of a liquid combination are vaporized and then compacted and sequestered.
Therefore, it is well described above.

The correct answer is C. Climate change
Explanation:
Long-term environmental changes occur as major events affect the environment and ecosystems indefinitely. These events differ from short-term environmental changes because the effect of short-term environmental changes is mainly temporary. Also, long-term changes are usually gradual.
Climate change is an example of long-term environmental changes because this implies indefinite and major changes in weather patterns and ecosystems. For example, it is believed climate change will decrease the amount of ice in Earth, change sea level, and lead to the extinction of dozens of species. This does not occur with events such as el niño or a small asteroid impact that affect the environment for a short time and do not imply major changes.
