<span>Energy is converted from solar to chemical in Process A and then from one form of chemical to another in Process B. Process A most likely describes a photosynthesis while process B would be respiration. Hope this answers the question. Have a nice day.</span>
Something that cannot be changed back ,
The overall concentration of hydrogen ions is inversely related to its pH and can be measured on the pH scale Figure 1 It is neither acidic nor basic, and has a pH of 7.0 Anything below 7.0 is ranging from 0.0 to 6.9)is acidic and anything above 7.0 from 7.1 to 14.0 is alkaline.
Answer:
The answer is "Choice A".
Explanation:
In this question, the choice A is wrong because when the copper panels on houses produce a patina (copper oxide) through occur as a consequence of reactions from oxygen and water in the air, these reaction does not have low activation energy because lower activation energy that is stored in a faster response rate.
Attached is the MOT of NO molecule.
1. Bond order is calculated is

In present case, number of e- in bonding orbital = 6
number of e- in anti-bonding orbital = 1
∴ Bond-order =

= 2.5
2. From the attached figure, it can be seen that NO has one unpaired electron in π* orbital.
