heres a math one If 3.0 moles of X and 5.0 moles of Y react according to the hypothetical reaction below, how many moles of the excess reactant will be left over at the end of the reaction? X + 2 Y “yields”/ XY2

OpenStudy (lovelyharmonics):

3.0 +2(5.0) -> 3.0(5.0)_2

ganeshie8 (ganeshie8):

think of it like this : X + 2Y you need 2Y for every X

OpenStudy (lovelyharmonics):

so i need 10.0y for every 3.0x?

ganeshie8 (ganeshie8):

suppose you need 1 icecream for every 2 questions you answer how many icecreams you will need to answer 5 questions ?

OpenStudy (lovelyharmonics):

2.5 icecreams

ganeshie8 (ganeshie8):

yes, 2.5 icecreams would be sufficient, the excess is 0.5 icecreams

ganeshie8 (ganeshie8):

icecream = X questions = Y

OpenStudy (lovelyharmonics):

huh .-. but you still have 2(5.0) so that does make 10? right?

ganeshie8 (ganeshie8):

the real question is this : I have 3 icecreams, and 5 questions with me. but you only charge 1 icecream to answer 2 questions

ganeshie8 (ganeshie8):

that means 0.5 icecream to answer 1 question so 0.5*5 icecreams to answer 5 quesitons

OpenStudy (lovelyharmonics):

so that means 0.5 of x would be left over

ganeshie8 (ganeshie8):

you will get 0.5*5 = 2.5 icecreams for answering 5 questions, the extra 0.5 icecream will be left over

ganeshie8 (ganeshie8):

yes ! pardon for the cheap analogy lol

OpenStudy (lovelyharmonics):

c: thank you i have more math questions if youd like to help
