Answer:
75 g
Explanation:
1 half life = 600/2 = 300g
2 half life = 300/2 = 150g
3 half life = 150/2 = 75g
Answer:
See explanation
Explanation:
The reaction of a benzyl bromide with a nucleophile may proceed by SN1 or SN2 mechanism depending on the nature of the solvent used.
Since SN1 reaction involves the formation of a carbocation, it usually predominates in the presence of a poor nucleophiles and protic solvents. Hence when methanol is used as solvent and a poor nucleophile is used, SN1 mechanism predominates.
However, when acetone which is an aprotic solvent is used in the presence of a good nucleophile, SN2 reaction mechanism predominates.
Hey there !:
HF s molecule with the strongest intermolecular force
<span>HF > HI > HBr > HCl</span><span>
</span>The main factor of influence at the boiling point is the question of intermolecular forces, but not only that, the molar mass also has influence (the greater the molar mass, the greater the boiling point). Note that the only one forming hydrogen bridges is the HF, therefore the largest boiling point, iodine, bromine and chlorine have the same type of intermolecular (permanent dipole) connections as they are polar, and what will differentiate the boiling point of each one is the molar mass.

The correct answer is c.
answer b is incorrect <span />
<span>The energy from the sun helps the tree in the process of photosynthesis?
The answer is </span><span>A.chlorophyll in the leaves capture the suns energy and uses it to make food from carbon dioxide from the atmosphere and water through the roots</span>
