Answer: Option (a) is the correct answer.
Explanation:
When is released from driving cars, some of which is absorbed by the plants but the rest of
reacts with the sea or ocean water.
It reacts with water molecules and changes the chemistry of ocean water by lowering its pH. As it is known that when pH becomes lower then the substance becomes acidic in nature.
Thus, we can conclude that driving cars lowers the pH of the oceans by releasing that dissolves and forms acid in the oceans.
Answer:
The reaction would take place with racemization.
Explanation:
The compound (R)-3-bromo 3-methylhexane contains has the leaving group attached to a tertiary carbon atom. When the leaving group is attached to a tertiary carbon atom, the compound undergoes nucleophilic substitution via SN1 mechanism. This mechanism involves the formation of a planar carbocation intermediate. The nucleophile may attack this intermediate from either faces, leading to racemization of the product.
<u>Answer:</u>
2400 mL
<u>Explanation:</u>
According to this equation, the stoichiometric ratio between and
for the complete reaction is 1:2.
We know that the number of moles of can be calculated using the mole formula. (<em>number of moles = mass / molar mass</em>)
Moles of Calcium = = 1.5 mol
So the moles of =
= 3.0 mol
<em>Volume of HCl solution = Moles of HCl/ concentration of HCl</em>
Volume of HCl solution = = 2400 mL
