Write a nuclear equation for the hypothetical fusion of a copper atom with another nucleus to make gold. Can this happen? Why or
1 answer:
Answer:
See explanation
Explanation:
What i have shown below in the image attached is a hypothetical nuclear fusion reaction that attempts to produce a gold nucleus by fusion of copper and barium.
This is not possible because nuclear fusion can only occur with two light nuclei and not two heavy nuclei such as copper and barium.
Hence, this reaction is not possible.

Answer : A nucleotide is composed of a phosphate group and a nitrogen-containing base.
Explanation :
Nucleotide : It is a building block of nucleic acids or we can say that it is building block of DNA and RNA.
It is composed of three sub-unit molecules which are a nitrogenous base, a five-carbon sugar and one phosphate group.
Nucleotide forms covalent bonds with other nucleotide for the formation of the nucleic acid strand.
Hence, a nucleotide is composed of a phosphate group and a nitrogen-containing base.
Answer:
12.19 hours prior to discovery was the corpse placed in the desert.
Explanation:
Heat required for fly eggs to develop into first instar larvae =
From the given,
Exposure time = 16 hrs
Temperature = 27 C
The day time exposed hours is 10 hrs.-(7.00am-5.00pm)
So, the extra heat = 427.2-378= 49.2
The addition heat divided by average temperature.
Average temperature = 22.4 C
So, the total time exposed is night time hours to day time hours.
= 10+2.19 = 12.19 hrs.
Therefore, 12.19 hours prior to discovery was the corpse placed in the desert.
