Dumbledore thinks the students are now confident with significant figures; snape is not so confident of begrudgingly snape decides to move forward in his lesson. his next lesson is in naming ionic compounds. he presents his students with sodium hydrogen sulfate and potassium permanganate. which pair of ionic formulas is correct for these two compounds?

(a) nahso3, kmno4
(b) nahso2, kmno4
(c) nahso4, kmno4
(d) nahso4, kmno3
(e) nahso3, kmno3

C)

Explanation:

- For the sodium hydrogen sulfate:

The ending -ate of the word sulfate indicates that the compound comes from the ion sulfate that is , so the compound formed by this ion will be

- For the potassium permanganate:

The ending -ate of the word permanganate indicates that the compound comes from the ion , so the compound formed by this ion will be

sodium (na), for example, has one electron in its valence shell. this is an unstable state because that valence shell needs eight electrons to be full. in order to fill its valence shell, find a way to add seven electrons to its valence shell
