Chemistry What Is the Correct Molecular Formula for a Decomposing Nitrogen Hydride?

AI Thread Summary
The discussion centers on identifying the correct molecular formulas for a decomposing nitrogen hydride and an oxide of nitrogen based on given reactions. For the first question, the decomposition of a nitrogen hydride producing 0.3 mol of gaseous elements indicates that the correct formula is N2H4 (hydrazine). In the second question, the reduction of an oxide of nitrogen producing an equal volume of nitrogen suggests that both N2O5 and N2O are valid formulas. Participants seek clarification on how to derive these answers through reaction equations. The overall conclusion is that both questions have the answer option B as correct.

What do you mean by possible equations? Can you solve 1 question for me so i can have 1 example to refer? ><
 
Reaction equations of decomposition reactions. For example:

2NH3 -> N2 + 3H2

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...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
