Answer:
Equilibrium will be shifted towards NO2 as it has the most of the moles in the reaction.
Explanation:
Hello there!
In this case, according to the equilibrium reaction between NO2 and N2O4, we are able to write:
We can recall the LeCha-telier's principle to realize that the increase of volume promotes the formation of the most of the moles, this is for NO2 because it has a coefficient of 2 and N2O4 a coefficient of 1; in such a way, we infer that the addition of argon, to increase the pressure, will shift the equilibrium towards NO2.

oxidation number is correct!! :)
Explanation:
Answer:
It will lose 2 electrons
Explanation:
Here we have a calcium atom, which has 20 electrons.
Those 20 electrons are in 4 shells. (2-8-8-2)
Saying there are 2 electrons in the valence shell (Shell N), to get to an octet with an ionic bond (with a group 16 element), those 2 electrons will have to go.
it's true. answer is B.
a hypothesis is a stage before formation of theory. so when we put forward a hypothesis to prove something (in scientific observation) it can be proven true with the experiments conducted.
but of course it's can be proven wrong too, after the experiments conducted. then it is disregard.
a proven hypothesis (a true hypothesis)is the reason for theories.
