    rewrite equations as balanced chemical equations
    Magnesium chloride yield sulfur dioxide


    Calcium carbonate yields calcium oxide plus carbon dioxide


    Nitrogen plus hygrogen yield ammonia

    Hydrochloric acid plus sodium hydroxide yield sodium chloride plus water

    Sodium plus water yield sodium hydroxide plus hydrogen gas

    Lead(II) oxide yields lead plus oxygen

    Copper plus silver nitrate yield silver plus copper (II) nitrate

    Potassium chlorate yields potassium chloride plus oxygen

    Calcium chloride plus silver nitrate yield silver chloride plus calcium nitrate

    Sodium bromide plus chlorine yield sodium chloride plus bromine

    Oxygen plus hydrogen yield water

    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)
