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.
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.
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.)
For A, by adding or taking away a charge from one of the two??
For B NO3 has the -1 charge
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.
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?
To solve this, you will need to understand how to determine the charges of the elements involved and how to write chemical formulas.
A. First, identify the elements involved: "melt X" and "nonment Y." Let's assume "melt X" is an element represented by X and "nonment Y" is represented by Y.
Next, determine the charges of the elements. It is given that melt X has a +2 charge and nonment Y has a -3 charge.
To write the formula, you need to balance the positive and negative charges. Since X has a +2 charge and Y has a -3 charge, you need to find the lowest common multiple of 2 and 3, which is 6. Multiply the charges by the appropriate numbers to balance them: X2Y3.
Therefore, the correct formula for this compound is "X2Y3".
B. In this case, the compound contains copper (II) and the nitrate ion (NO3).
First, determine the charge of copper (II). The Roman numeral "(II)" indicates a +2 charge for copper.
Next, determine the charge of the nitrate ion (NO3). The nitrate ion (NO3) has a -1 charge.
To write the formula, you need to balance the positive and negative charges. Since copper has a +2 charge and the nitrate ion has a -1 charge, you need to find the lowest common multiple of 2 and 1, which is 2. Multiply the charges by the appropriate numbers to balance them: Cu2(NO3)1.
However, in chemical formulas, when the subscript is "1", it is usually omitted. Therefore, the correct formula for this compound is "Cu(NO3)2".
In summary:
A. The correct formula for the compound composed of melt X (+2 charge) and nonment Y (-3 charge) is X2Y3.
B. The correct formula for the compound containing copper (II) and the nitrate ion (NO3) is Cu(NO3)2.
