element Q forms compounds with the element X and with element Z write the formulas for these 2 compounds?

There isn't enough information to write the formulas for any of the compounds formed.QX and QZ is the best I can do; however, we don't know the valencies so we don't know how many of the Q adds to X or Z.

We could write QaXb or QcZd where a,b,c, and d are small whole numbers.

QX and QZ

To determine the formulas of compounds formed between element Q and elements X and Z, we need to know the valency or the charges of each element.

Valency or charges determine how many atoms an element can bond with and in what ratio.

Let's assume the valency for element X is a and for element Z is b, and the valency for element Q is c.

Now, we can determine the formulas of the compounds formed with element X and element Z.

Compound with element X:
In a compound, the sum of the charges of all the elements involved must be equal to zero. So if element Q (charge = c) forms a compound with element X (charge = a), the ratio of Q to X should be in such a way that their charges add up to zero.

The formula for the compound formed between element Q and X would be QaC, where C represents the coefficient that represents the number of atoms required to balance the charges.

Compound with element Z:
Similarly, for a compound formed between element Q and element Z, the formula would be QbD, where D represents the coefficient.

Remember, the coefficients C and D are determined based on the ratio needed to cancel out the charges and achieve overall charge neutrality.

To summarize:
- Compound with element X: QaC
- Compound with element Z: QbD

Please note that these formulas are a general representation and may be modified based on the specific valencies of the elements involved.
