37.8 g CH2Br2 X (1 mol CH2Br2 / 173.83 g) = 4.60X10^-3 mol CH2Br2
<span>4.60X10^-3 mol CH2Br2 X (2 mol Br / 1 mol CH2Br2) X 6.02X10^23 atoms/mol = 5.54X10^21 bromine atoms.
I think this is the answer.</span>
Valence electrons are shared in covalent bonds
Answer:
heat from the sun,evaporation/transpiration,condensation precipitation
Explanation:
Lighter gases (in weight) diffuse and Effuse faster than heavier gases.
Answer:
As for what is written, I think that your wording is incomplete, since valine (abbreviated Val or V) is one of the twenty amino acids encoded by DNA on Earth, whose chemical formula is HO2CCH (NH2) CH (CH3) 2. In messenger RNA, it is encoded by GUA, GUG, GUU or GUC. Nutritionally, in humans, it is one of the essential amino acids.
Explanation:
Being an essential amino acid, it speaks of the fact that the organism does not synthesize it, therefore it must be ingested in the daily diet as well as in foods rich in proteins: red meat, chicken, fish, eggs, grains and nuts.
