Reaction Prediction - Is there a reaction?

AI Thread Summary
Sodium oxide reacts with water to form sodium hydroxide, represented by the equation Na2O + H2O --> 2NaOH. The discussion centers on understanding whether a reaction occurs, particularly when the states of matter are not specified. It is noted that metal oxides, especially from Group I and II, are basic and typically produce hydroxides when mixed with water. This general principle can help determine the likelihood of a reaction without needing to search for specific information. Thus, sodium oxide does indeed react with water to yield sodium hydroxide.

Homework Statement


sodium oxide plus water --> ?
Is there a reaction?

Homework Equations


sodium oxide plus water yield sodium hydroxide

The Attempt at a Solution


Na2O + H2O --> 2NaOH

I don't understand whether or not there is a reaction. The problem does not give any states of matter, so how can I determine whether or not there is in fact a reaction?

I was hoping for something a little more general, Bipolarity.
As in, how can one tell whether or not there is a reaction, without googling to find out.

Metal oxides are basic, particularly those of the Group I and Group II metals. This means they produce hydroxides when dissolved in water.

So you have,
Metal oxide + Water --> Metal hydroxide

Thread 'Confusion regarding a chemical kinetics problem'
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...
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...
