No, competing side reaction is a reson why the actual yield is more than the theoretical yield.
yes
Magnesium results in reaction with metals and oxygen. Therefore it stands to reason it reacts with magnesium oxide
for energy:) The major reason for chemical bonding is to produce energy. As a reaction occurs and begins to form products at a lower energy, energy must be released.
Who says they don't?There are only four terrestrial planets we have pictures of where they're more than a single pixel (if that). We don't know if extrasolar terrestrial planets have rings or not. There's no theoretical reason they COULDN'T have rings.
Objects in the Oort cloud have never actually been observed; they are more theoretical that actual at this point. The problem is that they are so far away - hundreds or thousands of AU away - that they are invisible in our current telescopes. This will probably change as telescopes of greater and greater power are developed. That said, there is no reason why an Oort Cloud object of sufficient size should not have moons. Asteroids have moons; Pluto has three moons. It's just that we haven't seen them yet.
yes
The reason this question doesn't have an answer yet is most likely due to the lack of information within it. What are your reactants and how many grams are you using of each?
product and reaction are equality favored in the reaction
what are some of the reasons for a gram-variable reaction
no actual reason
congress in order that one house might check on the other
oxidation
content is something that another thing holds and purpose is the reason of something or someone
There is no reason for that. It forms OH- after the reaction.
The main reason behind ozone hole is the reaction of the chlorine molecules from CFC's. These molecules initiate a chain reaction which then destroy the ozone molecules to form the ozone hole.
I kind of know why.. But what was the actual reason?? Any ideas?
Protest it, with an actual reason.
