I think you need to balance the equation yourself, in some situations they won’t give it to you balanced.

10:58 , we had ( Fe2 ) in the reactant then, we had ( 2Fe ) in the product, doesn't that make a difference? { I didn't even know what computational chemistry was, this is my introduction to it. So, forgive me if this is a silly question... )

in the case of balancing equations it does not make a difference as the no. of Fe going in is the same as the number of Fe going out. Also dont ever ask for an apology if you want to know something everyone had to start somewhere

at 3:39, why did you do oxygen twice? isn't it diatomic or is that not related to it?

@jamesthejoker7415 2 жыл бұрын

Just a small query, for the last bit when we calculate the mass of Iron using the mole ratio, would the RAM not be 112 instead of 56 because on the formula it says “2Fe” so would you not multiply 56 by 2?

@hellobroskiwhatsgood Жыл бұрын

sorry this is so late BUT noooo! as basically you would only multiply by 2 if it is the subscript (e.g Fe2) hope that helps :) the reasoning is that some elements are di-atomic meaning they come in pairs of two for (as the prefix 'di' suggests) for example O2, and this is their original form as they do not have a full outer shell by nature and therefore form covalent bonds with another atom of themselves to get to one - oxygen is in group 6 meaning 6 outer shell electrons which makes sense as they would form one covalent bond meaning they share a pair of electrons, this in turn gives them 8. However other elements may not be di-atomic by nature so you are changing their properties by multiplying them by 2. You can however use the multiple in front to determine how many moles you have of each substance for instance if you have the equation 2Fe + 3O you would have a molar ratio of 2:3 you can use this to later discover the limiting reactant, so the one that is consumed first in the reaction, and limits the reaction when it is consumed. Once again hope this helped! sorry it is so long and late!!
