Explanation:
Electroplating involves the coating of one metal on another metal. It is an electrochemical process. The positive electrode is the coating metal while the negative electrode is the metal on which the coating is to be performed.
Since copper is to be coated on an iron nail. A copper plate is made the positive electrode while the iron nail should be the negative electrode.
The electrolyte used in the process should be a copper salt e.g CuSO4 solution.
As electrolysis progresses, the copper electrode(positive electrode or anode) gradually wears away due to the fact that the copper ions are going into the solution and are being deposited on the iron nail.
Answer:
You have to use chargaff's rule:
A+G=T+C
A=T
C=G=32%
A+T=100-2x32=36%
A=18%
A=18% T=18%
Answer: <u>Option C; 48</u>
Explanation:
Let one number = x
Other number = x+2
According to question-
[x] [x+2] = 2400
+ 2x - 2400 = 0
Solving this equation, we get-
[x - 48] [x - 50 ] = 0
x = 48 or 50
Since 48 is the smaller number here, answer is option C
It will be half
A normal cell contains 46 chromosomes.
Gametes only contain 23 because they will be paired with an opposite gamete cell upon fertilisation
- Egg contains 23
- Sperm contains 23
Together they make the normal amount of 46
Answer:
Amino acids are organic compounds that combine to form proteins. Amino acids and proteins are the building blocks of life. When proteins are digested or broken down, amino acids are left. The human body uses amino acids to make proteins to help the body: Break down food.
