Explanation: i did it and got it right
Answer:
We would see 5 peaks. 35Cl the lightest and 37Cl2 the heaviest
Explanation:
The chlorine element has two isotopes (35 Cl and 37 Cl), in the mass spectrum we can observe the m/e of the diatomic molecules. Formed by an atom of chlorine 35 and another of chlorine 35. Or one of Cl 35 and one of Cl 37. Or both of Cl 37.
We can also observe the mass of each separately. That is why we would see 5 peaks.
- Cl = 35 <------------------------- lightest
- Cl = 37
- Cl2 = 35 + 35 = 70
- Cl2 = 35 + 37 = 72
- Cl2 = 37 + 37 = 74 <-------- heaviest
The answer is A I believe. If you are refering to the periodic table in this question, then the bottom left are the earth metals, transition metals, etc. The upper right corner are the noble gasses.
Water is technically a compound because it’s made up of hydrogen and oxygen.
