AI Thread Summary
NH4NO3 is classified as an ionic compound because it consists of the NH4+ ion and the NO3- ion. While the bonds within these ions are covalent, the overall structure is ionic due to the electrostatic attraction between the positively and negatively charged ions. The distinction between ionic and covalent bonds is crucial for understanding compound classification. Therefore, the initial classification of NH4NO3 as covalent is incorrect. The correct classification is ionic.

Classify each of the following as ionic or covalent. I did all but I am not really sure about this one. NH4NO3 I put covalent. Is this correct? Thanks

Well no because NH4NO3 is comprised of a NH4+ ion and a NO3- ion. The bonds in the ions themselves, however, are covalent, but the answer you are looking for is ionic.

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
