I dont understand how to do this so i need yalls help,

 

Write the Correct Name of The Following Formulas:

 

1. Calcium Chlorine

 

2. Copper Sulfate

 

3. Nickel Oxide

 

 

 

Im not goina ask for u guyz to do my home work but i would like some examples please

If I'm understanding the question properly, if it were "DiHydrogen Monoxide" the answer would be "water." So I guess each of those are assumed to have a more common name.

 

I'm assuming if they wanted the formula, they'd ask for the formula (e.g. H₂O) rather than the name

It has to be something like CH3Co-2 or something like that, its so freaking confusing i wish i could be smart science whizzes like you guyz

so, do you want the correct name (ie Sodium Cholride) or the formula (ie NaCl)?

The formula for the names listed above

 

its more like chemistry because he wants the Ion Formulas for the names

well, it is chemistry seeing as they are chemicals.

 

do you know about valences at all?

 

and there are two possible answers for the last one, were there any roman numerals along side the nickel part?

yea, i remeber he said something about valences.

 

But there where no roman numerals it was just

 

Nickel Oxide

 

I think that is Type I

If it's the chemical formula, then you have to decide how the pairs will combine. Sodium and Chlorine form an ionic bond, with each having one electron given/taken, so the formula is NaCl. You have to figure that out for the other atoms or molecules.

You just need to know the oxidation numbers, of the elements and based on that you can then put the indexes to equalize those oxidation numbers and this gets you to the correct formula.
