Answer:
Manganese decreases from 4+ to 2+ (reduced and oxidizing agent) and nitrogen increases from 2+ to 5+ (oxidized and reducing agent).
Explanation:
Hello there!
In this case, according to the given redox reaction, we rewrite it as a convenient first step:
Next, we assign the oxidation numbers as follows:
Thus, we can see that both manganese and nitrogen undergo a change in their oxidation number, the former decreases from 4+ to 2+ (reduced and oxidizing agent) and the latter increases from 2+ to 5+ (oxidized and reducing agent).

A) polyester, hope it was quick enough
Answer : The structural formulas for each of the possible isomers of n-hexene are shown below.
Explanation :
Isomer : It is defined as a molecule have the same molecular formula but the different chemical structure.
There are three structural isomers of n-hexene that is based on the location of the double-bonded carbon atoms with the other atoms.
In n-hexane, 'n' shows that the chain should be straight chain there is no branching.
The three structural isomers of n-hexene are:
(1) 1-hexene
(2) 2-hexene
(3) 3-hexene
Thus, the structural formulas for each of the possible isomers of n-hexene are shown below.
The kinetic theory states that matter consists of particles in constant motion.
Answer:
Carbon dioxide is moving out of the living things.
Explanation:
The food materials eaten by living things contain carbon in the form of complex organic matter. When living things feed, they ingest this complex organic material into their bodies.
During the process of digestion, this complex organic material is broken down to give glucose. Glucose is the energy molecule in living things. Excess glucose in the body is stored as glycogen.
During cellular respiration, glucose is broken down to release carbon dioxide. Hence, at night when the giraffe has stopped eating, cellular respiration continues to occur and carbon dioxide is released, that is, carbon dioxide continues to move out of living things at night.
