Answer 4

i have no idea!

Answer 5

sorry it is much to confusing!

Answer 6

lol its okay

Answer 7

good luck to you braving the harshness of that question

Answer 8

lolololo i know right.. i hate chem

Answer 9

i'm not good at stuff like this

Answer 10

we're looking for a increase in disorder, so that should be a solid going to a liquid or gas, or a liquid going to a gas

that rules out D which is hydrogen and oxygen forming water

Answer 11

A is sulfur dioxide plus oxygen making sulfur trioxide, which is a solid, so that's the wrong direction as well

Answer 12

B has a solid and liquid forming a solid, again, that's an increase in order
C has a gas going to two gases. that must be the answer!

Answer 13

ah, if you have gas to gas, the side with more moles of gas is the more disordered one.

Answer 14

thank youuuuuu !

Answer 15

he is much smarter than me :(

Answer 16

i wish i was that smart

Answer 17

me to

Answer 18

I didn't know anything about solving this problem before you asked it! I just did a web search for "reaction positive value S" and read until I found something that made sense. when I was your age, I would have had to flip through the chemistry book until I found something that looked right, you've got it easy :-)

Answer 19

took me a few minutes to realize that the "^S" meant delta S, though! I was wondering how exponents were going to come into this problem...
