Explanation:
Hello,
In this case, by considering the given seminormal solution, we infer it is a 0.5-N solution which means that we can obtain the equivalent grams as shown below for the 55 cc (0.055 L) volume:

Next, since sodium carbonate has two sodium ions with a +1 oxidation state each, we can obtain the moles:

Finally, the mass is computed by using its molar mass (106 g/mol)

Regards.
Answer:
Cu, Zn(NO3)2
Explanation:
Zn is more reactive than Cu, so Cu will be displaced (replaced) in the reaction above.
