Thank you for posting your question to the Ask Me Help Desk.

Let's start by having you write down for me what you think are all the chemical formulas that represent the words in each statement.

I did them could you check if they are right thank you

SYNTHESIS
S + O2 āSO2
O2+ 2H2--> 2H2O
N2+H2-> 2NH3

DECOMPOSITION
CaCO3 -> CaO + CO2
2KClO3 → 2KCl + 3O2
2PbO->2Pb+O2


SINGLE DISPLACEMENT
2Na+2H2O->2NaOH+H2
2NaBr+Cl2->2NaCl+Br2
Cu+2AgNO3->2Ag+ Cu(NO3)2

DOUBLE DISPLACEMENT
HCl+NaOH->NaCl+ H2O
MgCl2+H2SO4-> MgSO4+2HCl
CaCl2+2AgNO3->2AgCl+Ca(NO3)2

Excellent!

You just answered your own question. :D
You even went a step further and identified the type of reaction.

I knew you could do it!

Great Job!

Kerosene is a mixture of many different hydrocarbons, so I can't tell you how many atoms are in a molecule of kerosene.

Oxygen plus hydrogen yield water :

O+H-->H20 (the 2 is supposed to be a subscript by the way)
