both my shift buttons are broken sometimes it works. i think i got this question, another one is what special property of a substance encourages physical change of state?
Everything was good until this happened: An intermediate step in the production of battery acid, sulfuric acid, invoves the information of sulfur trioxide gas from sulfur dioxide and oxygen gases. (this reaction is also the usual first step in the
Another question is when you invert it and times everything by negative 3 it would make the rates positive on the reactants side and negative on the products side. When you get the rate for that, do you make it positive or negative and why?
I think that is good cause the rate is proportional to [A] as it is first order?
EMF = BLV i don't have the length but im trying to find the velocity?
nvm got it thanks :P
thanks!
Yeah, so therefor it is the same impulse? but J = FT The force is the same but the T interaction is different? or something?
