3H + 3Br = HBr9 Organic chemistry mechanism
ANSWER IS D.
EXPLANATION:
The electronic configuration of neutral Rubidium atom is 1s2,2s2,2p6,3s2,3p6,3d10,4s2,4p6,5s1.
when a monoatomic ion is to be formed the Rubidium atom loses one electron from 5s orbital so the electronic configuration for the ion is 1s2,2s2,2p6,3s2,3p6,3d10,4s2,4p6.
Vaccines are given to people so there body can reject the diseases in there body.
example. they inject they flu into yo arm so your body knows what it is and how to attack it when it threatens your body.
Answer:
8.1%
Explanation:
<h3><u><em>mass of glucose/ total mass of solution x 100</em></u></h3>
So first 265mg into grams = 0.265 g
0.265 + 3 = 3.265
mass of glucose= 0.265
total mass of solution= 3.265
0.265/3.265 x 100 = 8.1% (rounded to 2 s.f)
Answer:
Y: tRNA
Z: DNA
Explanation:
This question involves two different nucleic acid molecules that are involved in protein production. Xavier used a chart to highlight the functions these nucleic acids perform during protein synthesis.
- Transfer RNA known as tRNA is a type of RNA molecule found in the ribosomes. It functions to read the mRNA codon and carry corresponding amino acid to the ribosomes for linking with one another. Based on this, "Y" on the chart is a tRNA molecule.
- Deoxyribonucleic acid, also known as DNA, is a molecule found in the NUCLEUS whose function is to store the genetic information in the cell. DNA carries the information needed for the synthesis of protein. Based on this, Z is a DNA molecule.
