<h2><em><u>Option a</u></em></h2><h2>
<em><u>Weathering</u></em></h2>
Explanation:
<h3><em>Weathering is a term which describes the general process by which rocks are broken down at the Earth's surface into such things as sediments, clays, soils and substances that are dissolved in water. </em></h3>
<u><em>As weathered products are carried away, fresh rocks are exposed to further </em><em>we</em><em>athering</em><em>.</em></u>
Answer:
69.8%
Explanation:
k = 0.00813 sec-1
t = 44.1 s
What percentage of the compound has decomposed?
We can obtain this using the formular;
[A] = [A]o e^(-kt)
where;
Final Concentration = [A]
Initial concentration = [A]o
[A] / [A]o = e^(-kt)
[A] / [A]o = e^(-0.00813*44.1)
[A] / [A]o = e^(-0.359)
[A] / [A]o = 0.698
Percentage decomposed = Final Concentration / Initial concentration * 100
Percentage decomposed = [A] / [A]o * 100%
Percentage decomposed = 0.698 * 100 = 69.8%
Explanation:
from chemical basics is the law of solution concentration which is no. of moles÷ volume
The land is warm during the day. For example, if you near a sea early in the morning, you could see how cold, cool the place is.
