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:
2NH4NO3 —> 2N2 + O2 + 4H2O
Explanation:
We begin by writing the skeletal equation as shown below:
NH4NO3 —> N2 + O2 + H2O
The equation can be balance as follow:
There are 4 atoms of H on the left side of the equation and 2 atoms on the right side. It can be balance by putting 2 in front of H2O as shown below:
NH4NO3 —> N2 + O2 + 2H2O
Now we have a total of 4 atoms of O on the left side and 3 atoms on the right side. It can be balance by putting 1/2 in front of O2 as shown below:
NH4NO3 —> N2 + 1/2O2 + 2H2O
Now, multiply through by 2 to clear the fraction as shown below
2NH4NO3 —> 2N2 + O2 + 4H2O
Now the equation is balanced
Answer:
The hot water was better for removing the oil.
Explanation:
You can see that because the mass went down more with the hot water. So, that means that more oil was taken out of the feather with hot water.
Answer:
36.3
Explanation:
The full answer would be 36.3426, but because of the 0.21, you round it down to 3 sig figs.
