Hi, great vid, helped me a lot but I am still stuck on one point. what if the reaction has more stoichiometric coefficients on the left than on the right, like 2NO+2H2 --> N2 + 2H2O. we would have -4 squiggle on the left and +3 squiggle on the right and wouldn't have the conservation of quantity of matter. im probably not seeing something
That's no problem at all. It just means there are fewer *molecules* after the reaction than before. *Matter* is still conserved, because there are 2 N atoms on each side of the reaction, as well as 4 Hatoms and 2 O atoms. There is no such thing as conservation of squiggle. Some of the next few videos in the sequence will use some examples where the stoichiometric coefficients sum to a different number on the left and on the right.
@@PhysicalChemistry thanks a lot for the Quick answer. Now that you explained it it Made Sense to me. I think i understood the way it works. Thanks a lot for the help again, and you probably saved me a part of my chemistry exam tomorrow. I’m definitely subscribing to the channel !!
