Best ResponseYou've already chosen the best response.2Let's take c) first 1. first we look to see if there's any kind of charge on the molecule 2. then we look for the oxidation states of the element(s) 3. we multiply oxidation state by the number of atoms for that element 4. add them all up. so for \[NH_{4}^{+}\] We have 1 atom of nitrogen and 4 atoms of hydrogen. Hydrogen has an oxidation state of +1 and there are four atoms right? so that's +4 we realize that the charge on our compound is +1 so the oxidation states must sum up to +1. Now we have +4 for hydrogen, and what oxidation state for nitrogen will give us +1 total. that's 3. so nitrogen is 3 and hydrogen is +1 3 + 4 = +1 try choice D and tell me what you get

Best ResponseYou've already chosen the best response.2@Shaekitchen first step is there a charge on N2H4 ?

Best ResponseYou've already chosen the best response.0How do i tell like i know that H has 1+ and theres 4 of them so 4+ right? @Photon336

Best ResponseYou've already chosen the best response.2@shaekitchen read these rules below. these are the most important YOU MUST LOOK TO SEE IF THERE IS A CHARGE ON THE MOLECULE, as in an ion. IF THERE IS A CHARGE: The oxidation states must add up to that charge. IF THERE IS NO CHARGE: the sum of the oxidation states = zero.

Best ResponseYou've already chosen the best response.0so in N2H4 theres no charge correct?? @Photon336

Best ResponseYou've already chosen the best response.0sso then would the charge on N be 2+ ?

Best ResponseYou've already chosen the best response.0My computer isnt letting me use the drawing tool If i have N2O I have a charge on O of 2 right? Theres so many charges on O how do I know which one to use? @Photon336

Best ResponseYou've already chosen the best response.2You always ask this question first before doing anything @Shaekitchen is there a charge on the molecule? oxygen almost always has a charge of 2

Best ResponseYou've already chosen the best response.0Theres no charge on this molecule but if O is 2 doesnt that mean that N would just be 1?

Best ResponseYou've already chosen the best response.2almost, but no charge means oxidation states MUST = ZERO ask your self if you summed up those numbers would you get zero?

Best ResponseYou've already chosen the best response.0I got it it would be +1 Im going to do the rest on my own as my computer is slow thank you for your help @Photon336

Best ResponseYou've already chosen the best response.2@Shaekitchen great job, it's +1 remember to use those rules. you should be able to figure out the rest now take care
