My teacher wants me to solve this but she/he never thought us how so I need help solving this because I’m kind of confused on what to do and how to do it.

Question

1. Write the correct formulas for the following:

A. A compound composed of melt X which has a +2 charge and nonment Y which has a -3 charge (write it as “XY” including the correct subscripts as necessary.)

B. A compound containing copper (II) and the nitrate ion (NO3) which has a -1 charge.

Answer 1

You'll want the overall charge of the compounds to be 0. For A, how can you balance +2 and -3 to make an overall charge of 0?

For B, do you know how to find the charge of copper (II)? (Hint: it is in the name.)

Answer 2

For A, by adding or taking away a charge from one of the two??
For B NO3 has the -1 charge

Answer 3

No you don't do it by adding or taking away from the charge. You do it by multiplying the charges to make a common charge.

Answer 4

Okay I have 2 questions before solving this:

1.How is it supposed to look?
(Can I get an example of how I’m suppose to solve this)

2. Am I suppose to find a random element on the periodic table that equal the amount of charges it wants?
