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 is the symbol for moles using the ideal gas equation
vredina [299]

Answer: N is the numbers of moles

Explanation:

An ideal gas can be characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them may be deduced from kinetic theory and is called the. n = number of moles. R = universal gas constant = 8.3145 J/mol K. N = number of molecules.

Calculate the freezing point of a solution 1.25 g benzene (C6H6) in 125 g of chloroform (CHCl3).
posledela

Answer:

The freezing point for the solution is -64.09°C

Explanation:

This problem can be solved, by the freezing point depression. This colligative problem shows, that the freezing point of a solution is lower than the freezing point of pure solvent.

ΔT = Kf.  m

ΔT = T° freezing pure solvent - T° freezing solution

Kf = Cryscopic constant, for chloroform is 4.68

T°freezing pure solvent = -63.5°C

m is mol/kg of solvent → molality

Let's determine the moles of benzene

1.25 g / 78 g/mol = 0.0160 mol

Let's convert the mass of solvent to kg

125 g . 1kg / 1000 g = 0.125 kg

m = 0.0160 mol / 0.125 kg → 0.128 m

Let's go to the formula to replace the data

-63.5°C - T° freezing solution = 4.68 °C/m . 0.128 m

T° freezing solution = - (4.68 °C/m . 0.128 m + 63.5°C)

T° freezing solution = - 64.09°C
