When micelles are formed... The movement of the molecules gets restricted so shouldn't it result in a decrease in entropy?
But it is said that increase in entropy is the driving force behind micelle formation and that's what makes it spontaneous
When $8.70\:\mathrm{g}$ of $\ce{Al}$ is reacted with excess $\ce{O2}$, $12.8\:\mathrm{g}$ of $\ce{Al2O3}$ is obtained. What was the percentage yield?
Here is the balanced equation:
$$\ce{4Al + 3O2 -> 2Al2O3}$$
I am stuck on two problems dealing with reactants and products. Here are the two problems:
Calculate the mass of water produced when 4.27g of butane reacts with excess oxygen.
Calculate the mass of butane needed to produce 60.8g of carbon dioxide.
@orthocresol If instead of pining you here, do I flag such poor, old questions for moderator intervention, with custom message "poor question; won't help future visitors; please delete"
is that ok? (clarification: i will only flag like this when I come across such questions; I won't specifically go hunting for such poor, old questions just to inflate my flag count and use up all the flags in a day)
