Answer:
Urea
Explanation:
Amino acids are the monomeric units of proteins. They are bi-functional because they possess both an amino group (-NH₂) and a carboxyl group(-COOH). First class protein are essential ingredients for healthy human diet e.g milk, cheese, fish etc. Such proteins are broken down in the body by enzymatic hydrolysis to their constituent amino acids from which they are degraded into energy which is needed for growth and from which other life function is being synthesized. The result of this effect leads to separation of amine groups which are converted into urea by the liver.
This process is achieved by the deamination of excess amino acids that leads to the formation of urea which are excreted via the kidneys.
5.5 litres is the volume of chlorine gas at 38oC and 1.63 atm is needed to react completely with 10.4 grams of sodium to form sodium chloride.
Explanation:
data given:
mass of sodium chloride in reaction = 10.4 grams
atomic mass of one mole of NaCl = 58.44 grams/mole
balanced equation for the reaction:
2Na (s) + Cl2 (g) 2NaCl (s).
number of moles =
=
= 0.17 moles of Na in the reaction.
from the reaction,
2 moles of Na reacted with 1 mole of Cl2
0.17 moles of Na reacted with x moles
=
x = 0.35 moles of chlorine gas reacted to form NaCl
To know the volume following equation will be used:
PV = nRT
V = R=0.0826 L atm/Mole.K, T = 311.15, P= 1.63 atm, n= 0.35 moles
V =
V = 5.5 litres is the volume of chlorine gas formed at given conditions.
