Methionine, ch3sch2ch2ch(nh2)co2h, is an amino acid found in proteins. what is the hybridization type of each carbon, oxygen, th
Lady_Fox [76]
Answer 1) To find the hybridization of carbon we need to draw the lewis structure first; which is attached in the answer.

So the formula for finding hybridization is 
Lone pairs + Bonding pairs = hybridisation.

Here, in the molecule of methionine Carbon is bonded to all 4 atoms and has got no lone pairs so we will have;

0 + 4 = 4 which means it is sp^{3} hybridized.

Answer 2) For oxygen we can see in the lewis structure that it is having 2 lone pairs and double bonded with carbon atom, also there is another oxygen atom with two lone pair but bonded with carbon and hydrogen at the end.

So, in both the cases we can calculate;

where 2 lone pairs are present  
2 + 2 = 4 so, it will be sp^{3} hybridized.

So, Oxygen is also sp^{3} hybridized.

Answer 3) Nitrogen present in the methionine is bonded to carbon atom and hydrogen atoms and has only one lone pair on it.

So when we are substituting this in the formula we get 1 + 3 = 4;

which means 1 lone pair and 3 bond pairs so, it is also sp^{3} hybridized.

Answer 4) Sulfur atom in methionine is bonded to two carbon atoms forming a linear structure with 2 lone pairs on it.

So, it has 2 lone pairs and 2 bond pairs,

hence the hybridization will be  sp^{3} hybridized. 

As, 2 + 2 = 4 which means it is  sp^{3} hybridized.

What average global temperature is maintained when there is a balance in Earth’s energy budget?
Thepotemich [5.8K]
The incoming and outgoing energy at the Earth’s surface must balance. Or in other words,  the flow of energy into the atmosphere must be balanced by an equal flow of energy out of the atmosphere and back to space.<span>
Earth's Energy balance describes how the incoming energy from the sun is used and returned to space. All </span>of the energy entering earth’s atmosphere comes from the sun. Half of it is absorbed by the earth’s surface i.e. the land and oceans, 30% is directly reflected back to space by clouds and 20% is absorbed by the atmosphere and clouds.<span>Earth's </span>actual<span> average global temperature is around 14° C (57 F).</span>
