Answer:
Leucine, isoleucine and lysine are classified as <u>essential amino acids.</u>
Explanation:
Amino acids are the important biomolecules in which an alpha-carbon is attached to a side chain R, two functional groups and one hydrogen.
The two functional groups are: amine group (-NH₂) and carboxyl group (-COOH).
There are total <u>21 amino acids in a human body</u>.<em><u> They can be divided into two types: Essential amino acids and Nonessential amino acids</u></em>
Essential amino acids are the 9 amino acids that can not be produced by the human body and thus has to be taken through diet.
<u>Example: leucine, isoleucine, lysine.</u>
<u>Therefore, leucine, isoleucine and lysine are classified as essential amino acids.</u>
Answer:
Explanation:
There is a formula for this:
M = DRT/P where M = molar mass. This just derived from PV = nRT where you say n = grams/molar mass. However, just with this formula, we can get D which is density at STP (1 atm and 273K). We find that D = 6.52g/L.
Explanation: You cannot be convicted of a crime without evidence. You cannot be convicted of a state crime. You cannot be convicted of a federal crime. If there is no evidence against you, under the law, it simply is not possible for the prosecutor's office to obtain a conviction at trial. So, when you do have evidence it is really impossible to not get convicted unless the judge truly believes your side of the story and declares you not guilty.
I hope this helped :) If not i'm sorry!
Answer:
Mass of reactant and mass of product must be equal.
Explanation:
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Explanation:
This law was given by French chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
For example:
In given photosynthesis reaction:
6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂
there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.
The mass decreases but the volume stays the same
