Question

Which equation is a decomposition reaction?
Li2CO3 mc016-1.jpg Li2O + CO2
Zn + HCl mc016-2.jpg ZnCl2 + H2
Na2O + CO2 mc016-3.jpg Na2CO3
C6H12O6 + O2 mc016-4.jpg CO2 + H2O @sweetburger

Answer 1

is it the 2nd one

Answer 2

Li2CO3 = Li2O + CO2
Zn + HCl = ZnCl2 + H2
Na2O + CO2 = Na2CO3
C6H12O6 + O2= CO2 + H2O

Answer 3

never heard of the compound mc016-1.jpg must be pretty fancy

Answer 4

i fixed it

Answer 5

lol

Answer 6

remember its the breaking apart of a compound or molecule so which reaction does this?

Answer 7

the last one

Answer 8

C6H12O6 + O2= CO2 + H2O

Answer 9

no thats a combustion reaction as you see its a hydrocarbon reacting with O2 to produce H2O and CO2

Answer 10

Its going to be 1 reactant breaking into multiple products

Answer 11

so Na2O + CO2 = Na2CO3?

Answer 12

then it must be Li2CO3 = Li2O + CO2

Answer 13

it has multiple products

Answer 14

yes you are correct

Answer 15

Li2CO3 = Li2O + CO2 is the answer

Answer 16

yes
