The reaction between aluminum and an aqueous solution of copper(II) sulfate is represented by the unbalanced equation below.
Al(s) + CuSO4(aq) ==> Al2(SO4)3(aq) + Cu(s)
Identify the type of chemical reaction represented by the equation.
Balance the equation in your answer booklet, using the smallest whole-number coefficients.
_____ Al(s) + _____ CuSO4(aq) ==> _____ Al2(SO4)3(aq) + _____ Cu(s)
Explain why the equation represents a chemical change.
Determine the total mass of Cu produced when 1.08 grams of AI reacts completely with 9.58 grams of CuSO, to produce 6.85 grams of Al2(SO4)3.

Respuesta :

The reaction is a single replacement reaction, as the aluminum is REPLACING the copper attached to the sulfate. the exponents on the equation, in order, would be 2, 3, 1, 3. The reaction represents a chemical change because a new compound is being formed; if the original compound was simply changing state ( from liquid to gas, etc), then the change would be physical.
The last question requires some stoichiometry. My work is attached.
