Iron does not rust from oxygen itself. Iron needs to be in contact with H2O, which is water and oxygen. So just keep iron out of contact with water, or when you do, make sure you wipe the iron dry. :) Hope this helps!
Answer:
Fe 3+
Explanation:
iron is Fe and it's 3 and has positive
Answer:
Molarity = 0.5 M
Osmolarity = 0.5 x 2 = 1 Osmpl.
Molecules of Cl2 = 6.02 x 
/ 4= 1.505 x no. of molecules
Explanation:
If we add half mole in 1L volume than molarity will obviously be 0.5 M.
The osmolarity is molarity multiplies by number of dissociates of solute that for CaCl2 are 2. So, 2 x 0.5 = 1
Half will be molecules of Ca and half will be of Cl2 for 0.5M.
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.
