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)
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
the compound will be CO2
this is a combustion reaction, the products are always carbon dioxide and water.
ok i see thanks
