Delta waves are associated with a deep sleep~
Answer:
pH = 4.17
Explanation:
According to the molar concentration you stated, pH of the solution is: 4.17
Remember that pH = - log [H⁺]
and [H⁺] = 10^-pH
When:
pH > 7 → Basic solution
pH = 7 → Neutral solution
pH < 7 → Acid solution
I am assuming that the apparatus you're referring to would be a container wherein there is water placed inside. To answer your question, I expect the water level to rise when it's placed in warm water and I expect it to fall when placed in cool water. This is because the water molecules get excited when placed in water molecule, thus, moving with more kinetic energy. The opposite goes with cool water.
Answer:
The new volume of the gas is 4.74L
Explanation:
Data;
T1 = 14°C = (14 + 273.15)K = 287.15K
V1 = 4.5L
T2 = 29°C = (29 + 273.15)K = 302.15
V2 = ?
From Charles law,
The volume of a fixed mass of gas is directly proportional to its temperature provided that pressure remains constant.
Mathematically,
V = kT
k = V1 / T1 = V2 / T2 = V3 / T3 = .............= Vn / Tn.
V1 / T1 = V2 / T2
Solving for V2
V2 = (V1 * T2) / T1
V2 = (4.5 * 302.15) / 287.15
V2 = 4.735L
V2 = 4.74L
The new volume of the gas is 4.74L
Amino acids combine to form a dipeptide molecule, but their reaction is a condensation reaction.
