Answer:
Cupric ions
Explanation:
In the single displacement reaction shown, the cupric ions lost two electrons.
Cu²⁺ + 2e⁻ → Cu
The replacement of a metallic ion in solution by a metal atom higher in the activity series than than the metal in solution falls into this category of reactions.
Since Zn higher in the series, it displacements the cupric ions.

Answer: because if there was no balance the equation will not work
Explanation:
basically it needs to be balance because if there is more weight in one side the other side is going to be unbalance
Answer:
Explanation:
Hello,
In this case, the formula to compute the required heat based on the mass, specific heat and change in temperature is widely known as:
In such a way, since we are asked to compute the specific heat, we solve for it as shown below:
Best regards.
Explanation:
c. positive., it gains electrons
