KCIO3.....KCI+O2
NaOH+CO2...Na2CO3+H2O
Cu2O+H2....Cu+H2O
Fe+H2O.....Fe3O4+H2
CH3OH+O2......CO2+H2O
AgNO3+BaCl 2.....Ba(NO3)2+AgCl
H3PO4+NanOH.....Na3PO4+H2O
P4+O2..P4O10
Zn+HCI...ZnCl2+H2
SiO2+C.....SiC+CO2
MgO+H2SO4.....MgSO4+H2O
As4+O2.....As4O6
Cu+AgNO3.....Cu(NO3)2+Ag
C2H5OH+O2....CO2+H2O
H2S+O2.....H2O+SO2
Al2O3+HCI..AlCl3+AlCl2+H2O
MnO2....Mn3O4+O2
Al+Fe2O3....Al2O3+Fe
Na+H2O...NaOH+H2

Answer 1

I already got the answers for the first 9, but i have no idea if they are correct or not.

Answer 2

post your work and then someone might comment

Answer 3

ok, one moment, here is the first 9

Answer 4

Zn + 2HCl..ZnCl2+H2
SiO2+C....SiC+CO2 (balanced)
MgO+H2SO4...MgSO4+H2O (balanced)
As4+O2......As4O6 (balanced? because 4+2=6)
2Cu+AgNO3......Cu(NO3)2+Ag

Answer 5

As4+O2......As4O6 (balanced? because 4+2=6)?????

As bal your O's are not

Answer 6

C2 H5 O2 H+O2.....CO2+H2O ?
H2S+O2.......H2O+SO2 (balanced)
Al2 O3+H2 CI......AlCl3+H2O

Answer 7

As4+O2........As4 2O6 ?????

Answer 8

no try again

Answer 9

hint change left side

Answer 10

2Cu+AgNO3......Cu(NO3)2+Ag

this needs work (NO3)2 one on left side 2 on right??

Answer 11

As4+O2........As4 2O6 ?
but how can i change the 6? it makes no sense, since there are only 2 O molecules?

Answer 12

As4+3O2........As4 2O6

3*O2 = 6 O's

Answer 13

so: As4+3O2......As4O6

Answer 14

you have to multiply the subscript by coefficient

Answer 15

ok, so O is now correct, since 2*3=6, and the right side of the equation has 6 O molecules

Answer 16

yes

Answer 17

ok, thanks!

Answer 18

2Cu+AgNO3......Cu(NO3)2+Ag

this needs work (NO3)2 one on left side 2 on right??

do this because i have to go

Answer 19

ok

Answer 20

Cu+AgNO3......Cu(NO3)2+Ag
Is it already balanced???

Answer 21

no you have (NO3)2 on the right and only 1 on the left

Answer 22

so: Cu+2AgNO3....Cu(NO3)2+Ag

Answer 23

now you have 2 Ag's on right and one on left

Answer 24

Cu+Ag 2NO3........Cu(NO3)2+Ag
or would I need "( )"???

Answer 25

Cu+2AgNO3......Cu(NO3)2+2Ag

that is balance
1Cu L--1Cu rt
2Ag L--2Ag rt
2NO3 L --2NO3 Rt

gotta run good luck!! just count

Answer 26

Omg! That's...a lot of questions. lOL

Answer 27

which ones do you still need help with?
