Thank you for being helpful in the past. Could you check my interpretation of the three chemical word problems below,and,let me know if I'm on the right track?

1.Determine the mass of water vapor formed when 1.00g of Butane (C4H10)is burned in a lighter(combined with Oxygen)to produce water and Carbon Dioxide.
C4H10(aq) + O2(g) ---> 5 H2O(g) + 4 CO2(g)

2.How much Barium Chloride would be necessary to react with Silver Nitrate,if you have 5.0g of Silver Nitrate ?

BaCl2(aq) + AgNO3(aq) ----> Ba(NO3)2 (s) + AgCl(aq)

3. What mass of precipitate should form if 2.00g of Silver Nitrate is reacted with excess sodium sulfide solution?
2AgNO3(aq) + Na2S(aq) ---> Ag2S(aq) + NaNO3(s)


  • Chemistry -

    I don't think the equations are balanced (although, in some cases, the part that needs to be balanced is ok). However, it is good practice to have ALL of the equation balanced.
    I have balanced them below and in bold face type I have correct the phases.
    2C4H10(gas) + 13O2(g) ---> 10 H2O(g) + 8CO2(g)

    BaCl2(aq) + 2AgNO3(aq) ----> Ba(NO3)2 (aq) + 2AgCl(s)

    2AgNO3(aq) + Na2S(aq) ---> Ag2S(s) + 2NaNO3(aq)
