Amino acids are the monomers that make up proteins. Each amino acid has the same fundamental structure , which consists of a central carbon atom, also known as the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom.
Answer:
the solubility of the ionic solid decreases
Explanation:
If a salt MX is added to an aqueous solution containing the solute AX, the X^- ion is common to both of the salts. The presence of X^- in the solution will suppress the dissolution of AX compared to the solubility of AX in pure water. This observation is known as common ion effect in chemistry.
The origin of common ion effect is based on Le Chatelier's principle. The addition of a solute will drive the equilibrium position towards the left hand side.

Answer:
Yup! The answer is 50 J/g* °C
Explanation:
I also took the test but I know how to work out the problem for anyone who wants to know how to solve it.
Remember the formula q = m*C*ΔT
m = the mass in grams
C = the specific heat Capacity
ΔT = change in time
q = amount of energy
So, find out what was given and what we need to look for:
m = 40 g
C = ?
ΔT = we're heating up (the temperature increases) a chemical so it needs to be a positive number. 25 - 10 = 15 °C
q = 30000 Joules
Now, set up the equation:
q = m*C*ΔT
30000 = 40 * C * 15
Multiply 40 and 15 to get 600:
30000 = 600 * C
Divide both sides by 600 to get C by itself (plug this into your calculator):
30000/600 = 600 * C/600
You are left with 50 = C
Now, you just need to plug in the units to get B. 50 J/g* °C
I hope I helped clear up any confusion! :D
