6 0

Answer:

The answer to your question is: Phosphorous acid

Explanation:

Phosphorous can form 2 main acids

                              H₃PO₃      is called phosphorous acid  

                              H₃PO₄      is called phosphoric acid

Using these metal ion/metal standard reduction potentials calculate cell potential for Cu2+(aq) + Cd(s) →Cd2+(aq)+ Cu(s) Cu2+(aq
Katena32 [7]

Solution :

Cd(s) ---------------------->  Cd^{+2} (aq) + 2e^-      ,     E_0  =   0.34 v

Cu^{+2}  (aq)  +   2e^-  ------------> Cu (s)             ,     E_0  =  -0.04 v

----------------------------------------------------------------------------------------------

Cd(s)  +  Cu^{+2}  (aq)  ------------->  Cd^{+2} (aq)  +  Cu (s)   ,      E_0  =  0.30 v  

The cell potential is defined as the measure of \text{ potential difference }  between the \text{two half cells} of an electrochemical cell.

If a polypeptide synthesized by a ribosome contains 99 amino acids in the chain, how many codons (including the start and stop c
Rudiy27

Explanation:

<u>-101 mRNA codons</u>

<u />

In the genetic code, an amino acid is encoded by 3 nucleotides, while there are just 4 bases . Each amino acid is specifically encoded by a codon- a triplet sequence of nucleotides...

Thus 99 amino acids= 99 codon sequences.

...along with a start and stop codon, this would require 101 mRNA codons

Further Explanation:

The nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They differ from other macromolecules since they don’t provide the body with energy. They exist solely to encode and protein synthesis.

Basic makeup: C, H, O, P; they contain phosphate group 5 carbon sugar does nitrogen bases which may contain single to double bond ring.

Codons are three nucleotide bases encoding an amino acid or signal at the beginning or end of protein synthesis.

RNA codons determine certain amino acids so the order in which the bases occur within in the codon sequence designates which amino acid is to be made bus with the four RNA nucleotides (Adenine, Cysteine and Uracil) Up to 64 codons (with 3 as stop codons) determine amino acid synthesis. The stop codons ( UAG UGA UAA) terminate amino acid/ protein synthesis while the start codon AUG begins protein synthesis.
