1. CaS 2. Nitrogen forms an anion with a -3 charge. 3. S 4. Ca2N3 5. Mg3N2. Magnesium nitride 6. CaO. So 1,1 7. 2- O2- (2- is super scripted). It is also an anion, which is a negatively charged ion. 8. That would be aluminum iodide AlI3, also called aluminum triiodide. 9. LiCI These should be correct. Hope I helped. ^~^

- A. Ba_2O is not the correct formula.

Explanations:- Charge for Ba is +2 and charge for O is -2, Here the charges are in equal and opposite so their ratio is 1:1 and hence the formula must be BaO and not Ba_2O .

Rest of the formulas are correct as charge for Ca is +2 and charge for N is -3 . On criss cross we get the formula Ca_3N_2 .

Charge for K is +1 and charge for Cl is -1 and so KCl is correct.

Charge for Li is +1 and that for S is -2. On criss cross we get the formula Li_2S .

Explanation:

Not balanced.

Li charge of 1, CO3 charge of -2, cross the two, should be Li2CO3

the correct answer would be squared form

please mark as brainliest <3

The correct formula unit should bear correct subscripts coming from the opposite charge of the other ion after the exchange. In this case, Ca2N3 is not correct since Ca has a charge of +2 and N has a charge of -3. Hence the correct should be Ca3N2.

Explanation:

A formula unit in chemistry is the empirical formula of an ionic or covalent material hard compound used as an objective item for stoichiometric calculations. It is the cheapest whole number ratio of ions designed in an ionic compound.

The squared form is not a correct form of the quadratic function.

Step-by-step explanation:

Given some forms of quadratic equation. we have to choose the form which is not correct of the quadratic equation.

As the general form and the standard form of quadratic equation is

y=ax^2+bx+c where a,b and c are constant.

Also, the vertex form is

y=m(x-a)^2+b where (a,b) is vertex.

Only the three forms of quadratic equation exist. No other form like squared form exist.

Hence, the squared form is not a correct form of the quadratic function.

Ca2N3 is not correct because the the numbers dont match up when you go back and look at the periodic table

Answered: ineedhelp2285

The answer is squared form.
