Question

Who can write the correct formulas for the products to these combustion reactions?

C25H52+02 -->_________
^these numbers are written smaller next to the chemicals.

C2H5OC2H5+O2 -->

C4H9OH+O2-->

Answer 1

combustion always produce CO2 AND H2O

Answer 2

yeah i know but i need to balance them

Answer 3

C25H52 + 38 O2 --------> 25 CO2 + 26 H2O

Answer 4

do u get it ?

Answer 5

yeah i see that each side is balanced equally when multiplying the number in front by the little number so that it comes out equal. i dont get why the C25 comes out as 25CO2 because i thought that would make it have to be C50 on the other side. the next one seems really complicated

Answer 6

ok i see wht u mean
the 25 CO2 means that 25( C) AND 25 ( O2)
so the 25 in the front makes 25 CARB0N AND 50 OXYGEN

try this,
25 CO2 = 25 C + 50 O
25 C2O2 = 50 C + 50 O

Answer 7

unless here is a litte num with the element the big num in the front will stay the same

Answer 8

That makes a lot more sense now. Thank you!

Answer 9

no prob
good luck
