<em>Answer:</em>
There are two major resonance contributors for the en-amine. One contributor have no formal charges, only have one lone pair at N while the other one has positive and negative formal charges.
<em>Explanation:</em>
An en-amine is formed by the condensation reactions of aldehydes or ketone with secondary amine.
The contributor<em> </em>I have no formal charges. It has only one lone pair at Nitrogen atom.
The contributor II has +1 formal charges at N, and -1 formal charges at α Carbon.
Please see attachment. The resonance contributor are given.
Answer:
quartz and olivine
Explanation:
According to my research on studies made by different geologists on Bowen's reaction series, it is known that crystal settling should result in the magma being separated in lower layers rich in the early-formed quartz and olivine minerals.

I could help but I don't understand the question
Explanation:
Answer:
=745 Kelvin
Explanation:
- According to the pressure law the relationship between the pressure and absolute temperature of a gas at a constant volume is directly proportional.
- An increase in temperature causes a corresponding increase in pressure at a constant volume.
That is;
Mathematically;
When there are two varying conditions;
In this case;
P1 = 0.8 atm
T1 = 25+273 = 298 K
P2 =2.00 atm
T2= ?
Therefore;
Therefore, the temperature can be raised up to 745 kelvin without bursting vessel.
Answer:
The lowest region of the atmosphere
