Answer:
A.It is a reaction involving pi-electrons.
D.It is *not* a reaction favored by entropy considerations.
Explanation:
The Diels-Alder reaction is a [4+2]- cycloadition that involoves pi-electrons (4 from the diene and 2 from the dienophile).
The reaction is favored by the formation of new sigma bond, since they are more stable than pi-bonds. This reaction is not favored by entropy because there are 2 reactants and one product and the order increases.
The reaction happens in one step.
Answer:
The answer to the question is true.
The equation of the reaction is:
Na2CO3 + AgNO3 → NaNO3 + Ag2CO3
but this equation, not a balanced equation so let's make it a balanced equation:
- we will start with Na number of atoms, we should make the Na atom number is equal on both sides.So we put 2 NaNO3 instead of NaNO3
- and then the Ag atom, we put 2AgNO3 instead of AgNO3 to make the number of Ag on each side are equals.
So the final balanced equation for this reaction is:
Na2CO3(aq) + 2AgNO3(aq) → 2NaNO3(aq) + Ag2CO3(s)
SO know we have number of Na on each side = 2
number of Ag on each side = 2
Answer:
Short Reflexes
Explanation:
Short Reflexes reflexes are stimulated by stretching or chemical stimulation of the myenteric plexus, it may result in Peristaltic Contractions,
Explanation:
Incomplete combustion would result in C02, smoke,smoldering due to lack of 02, carbon monoxide, and h2o...
