To assign a priority to an atom that is part of multiple bonds, treat the multiple bonds as an equivalent number of single bonds. Hence, option A is correct.
<h3>What is a stereogenic centre?</h3>
A carbon atom is a chiral (stereogenic) centre if it is tetrahedral (sp3) and has four different groups (ligands) attached to it.
To assign a priority to an atom that is part of multiple bonds, treat the multiply bonded atom as an equivalent number of singly bonded atoms.
If two isotopes are bonded to the stereogenic centre, the isotope with the higher mass number has a higher priority.
Hence, option A is correct.

Answer:
Explanation:
N = Final mass of atom = 125 g
= Initial mass of atom = 16000 g
t = Time taken = 163.24 days
= Half life
We have the relation
The half life of the atom is .
Dimension analysis is to be used to solve this problem. First convert 1L to milliliters. That is equivalent to 1000 ml. Then by dimension analysis, multiply the volume ( 1000ml) to the density of oil (0.92 g/ml) resulting to the answer: 920 grams.
Answer:
To reduce acid rain.
Explanation:
Sulfur often removed from fuels before they are burnt because when sulfur is burned it get converted into sulfur dioxide and when sulfur dioxide mix with atmosphere, it can cause acid rain which is very harmful.
So, in order to reduce acid rain, sulfur often removed from fuels before they are burnt.
Hence, the correct answer is "To reduce acid rain."
Either NaI or INa are acceptable formulae for sodium iodide, which is indeed a binary ionic compound. So, the correct answer would be B.
