Question

the chemical reaction in which copper oxide and sulfuric acid are mixed together is called
a single - replacement
b synthesis
c decomposition
d combustion reaction
e double - replacement
check it

Explanation:

Copper oxide (\(CuO\)) and sulfuric acid (\(H_2SO_4\)) react as \(CuO + H_2SO_4=CuSO_4 + H_2O\). In a double - replacement reaction, the positive and negative ions of two ionic compounds exchange places. Here, \(Cu^{2 +}\) from \(CuO\) and \(H^{+}\) from \(H_2SO_4\) exchange their anions (\(O^{2-}\) and \(SO_4^{2 -}\)).

Answer:

e. double - replacement
