Explanation:
Answer:
Reaction of 1-butanol with bromobenzene
Explanation:
The reaction would yield ether as the major product is the reaction of the 1-butanol with bromobenzene. This is because the reaction does not have the large percentage of the undesired side product. In fact, the major product is about 85 % in composition, compared to the 15 % of the minor product. Hence, the reaction is efficient.
Answer:
Many plants have thorns on their stems or leaves. What is the MOST likely explanation for the evolution of thorns?
A) Thorns help plants produce more food from photosynthesis.
B) Thorns are an example of a mutation that arises in the genetic code of plants.
C) Thorns help plants to conserve resources like water and soil nutrients that may be used by other organisms.
D) Thorns are an adaptation that some plants have evolved in order to discourage herbivores from eating the plant.

Explanation:
Answer:
0.68 V
Explanation:
For anode;
3Mg(s) ---->3Mg^2+(aq) + 6e
For cathode;
2Al^3+(aq) + 6e -----> 2Al(s)
Overall balanced reaction equation;
3Mg(s) + 2Al^3+(aq) ----> 3Mg^2+(aq) + 2Al(s)
Since
E°anode = -2.356 V
E°cathode = -1.676 V
E°cell=-1.676 -(-2.356)
E°cell= 0.68 V
Answer:
neutrons should be added with the protons
