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

Answer:
Percent yield of hydrogen is 87.096%
Explanation:
Theoretical yield = 155g
Experimental yield = 135g
% yield = [experimental yield / theoretical yield] * 100
% yield = (135 / 155) * 100
% yield = 0.87096 * 100
% yield = 87.096 %
The percentage yield of hydrogen is 87.096%
