Answer is: the ionized state of the carboxyl group is COO⁻.
Physiological pH is 7,4 and carboxyl group in the R group has pKa = 3,7. Since this pKa is lower than phys<span>iological pH of 7,4, carboxyl group (COOH) will lost proton, and because of that it will be deprotonated and will have negative charge.

239,2 g/mol x 3,7 mol = 885,04 g
The phase is Waning Crescent phase.
Answer: The final temperature would be 1250.7 K.
Explanation: We are given a sample of helium gas, the initial conditions are:
(Conversion factor: 1L = 1000 mL)
(Conversion Factor: 1° C = 273 K)
The same gas is expanded at constant pressure, so the final conditions are:
To calculate the final temperature, we use Charles law, which states that the volume of the gas is directly proportional to the temperature at constant pressure.
Putting the values, in above equation, we get:
The chemical bonds in CH4 are all single bonds. C only can bond 4 times because it needs 8 electrons in it's outer shell and only has four right now. The bonds represented are all single bonds because there are two electrons present on each side of the carbon. Two electrons, in this case, equals one bond.
