It is B, I believe. Sorry if I am wrong! Hope I helped! ^_^
<span>C. a carbon chain with a carbonyl group bonded to one end

<span>HI because the degree of iconic character can be determined based on differences in electronegativity which for HI is .5. Also, Hydrogen Iodide is made up of Hydrogen Halide and a Diatomic Molecule, both of which are non-metals. HF is 1.9, HCL is .9, and HBR is .7; hence HI being the correct answer.</span>
Answer:
A diamond is a pure substance because it is made of one element.
Explanation:
From the crystalline structure model of the diamond, we can see that we only have just one element represented by the green balls connected in a cross linked fashion to one another. Therefore, one can rightly conclude that this is a pure substance made up of one element.
In a pure substance, all parts are homogeneous and composition is definite.
Strong acids are those that dissociate completely into their ions. So the dissociation equation for a strong acid is:
HA → H⁺ + A⁻
It is visible from the equation that the number of moles of hydrogen ions released is equivalent to the number of moles of acid. For a given volume,
[HA] → [H]⁺ + [A]⁻
Thus, the assumption is logical and fairly accurate
