Calculate the percent ionization of nitrous acid in a solution that is 0.210 m in nitrous acid (hno2) and 0.290 m in potassium nitrite (kno2). the acid dissociation constant of nitrous acid is 4.50 ⋅ 10-4.

b i think it’s a water wheel turning in a stream

no but i do not usually comment or use my voice that much when it comes to social media

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
