87) Hydrogen and chlorine both have two naturally occurring isotopes: 1H (1.0078 amu; 99.985 percent abudundance) and 2H (2.01410; 0.015 percent abundance), 35Cl (34.969 amu; 75.53 percent abundance) and 37Cl (36.966 amu; 24.47 percent abundance). a) How many peaks would be expected in a mass spectrum of HCl(g)? b) At what molecular weights will peaks be observed? C) What should be the relative intensities of the peaks?

answer: your mm

explanation:

what is the average time it took the car to travel 0.25 meters?

⇒ 2.23 seconds

what is the average time it took the car to travel 0.50 meters?

⇒ 3.13 seconds

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
