Which chemicals are reactants? 0: NH₃ + 0 02
0:02 0: N2 + 0:420
A. NH3 and O2
B. O, and H2O
C. N, and H2O
D. NH3 and N2

im not exactly sure but i think its b!

a electronegativity decreases beacuse the size of nucleus is bigger.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.

wher is the rest of the question
