Answer:
B
Step-by-step explanation:
When given a written name, there are ways to assess clues on how to determine the formula.
First, charges are assumed for the cation, unless it is explained. The charges for the non-metals and metals are known; however, transition metals change in charge from time to time, so they are noted with a parenthesis, and a number in between.
In this example, we know that Copper (Cu) has a charge of +2.
Next, find the identity of the anion. Sulfate is actually a polyatomic ion; most likely will be a memorization factor in collegiate chemistry classes. Sulfate's notation is
, which means it has a -2 charge.
Lastly, balance. Remember, the charges have to add up to zero for a normal compound; therefore, since Copper (Cu) has a charge of +2, and
has a charge of -2, no balancing of the cation or anion is needed.
will be your final answer.
