**ALGEBRA **

alright. the first one would be easiest if you multiplied out the numbers before the parenthesiss into the numbers inside. so itll look like 50=3r+48-2r+4.the u can simplify the right side and get 50=r+52. subtract 52 from both sides and your answer is r=-2 the second one firs...

now you just multiply them. the number you had before was right just not the whole cancelling out stuff.

**chem 1406**

you had it set up right before. ur messing up the algebra. you were solving for the x kj so in order to do that you would have to multiply both sides by the 2000 moles. the moles and 200o would cancel on one side and just the moles on the other. but your number is correct. if ...

**chem 1406**

you shouldve got a bigger answer and ur solving for the kj not kj/mol. remember you have to multiply the 2000 moles by the 4130 kj/mol to get rid of the mole.

use the equation drbob222 gave you before. its the right one. you may have to convert the 5 L to mL first though for it to work or understand that ur answer is in L and convert it. one or the other
