Of the same element with different mass numbers are called isotopes 3) Isotopes have the same number of protons but different numbers of neutrons in their nuclei. ... The 63Cu isotope has 63 - 29 = 34 neutrons. The 65Cu isotope has 65 - 29 = 36 neutrons.
B)all solutions are mixtures
The correct answer is -2 oxidation state.
Assume that the oxidation number of the sulfur atom in H2S S is x.Now, 2+x=0 ⇒ x=−2. As a result, the oxidation number of sulfur in H2S is -2. Various organosulfur compounds are produced by combining Hydrogen sulfide with sulfur. Sewer gas, swamp gas, stink damp, and sour damp all include Hydrogen sulphide, an invisible gas. It smells strongly of eggs, even in small amounts. It is extremely flammable and poisonous. While drilling for and producing crude oil and natural gas, gases like Hydrogen sulfide (H2S) are regularly found.
