Classify each of the following reactions in as many ways as possible. (Select all that apply.)

CuO + 2 HCl --> CuCl2 + H2O

you can select:
-acid-base(unsure because there is an acid but im not sure if theres a base)
-gas evolutionx
-oxidation-reduction x
-single-displacement x
-synthesis x

the ones i have X's on are the ones im pretty sure are not it.

    there is NO precipate. Metal oxides act as bases (remember definition of a base: it neutralizes acids...) Calcium oxide is a great base (quicklime).

    thanks. so would it be double displacement and acid-base?

    thanks you so much. Also if i may ask im having trouble on another type of problem balancing this equation:

    C5H12O(l) + O2(g) --> H2O(g) + find the compound here

    I am able to balance it but i need to find the last compound i though it would be:

    C5H10O2 because i took out 2 H's and 1 O. but it was wrong

  • chem -

    the compound will be CO2
    this is a combustion reaction, the products are always carbon dioxide and water.

  • chem -

    ok i see thanks

  • chem -

    oops sorry
