Write the chemical formula of the ionic compound made with sodium and oxygen. Step 1: find sodium in the periodic table, note symbol and charge Step 2: find oxygen in the periodic table, note symbol and charge Step 3: balance the charges to make it neutral l​

Formulas for ionic compounds contain the symbols and number of each atom ... that this compound is made up of twice as many sodium ions as sulfide ions. ... how to find the correct ratio of ions, so that you can write a correct formula. ... +3 = -3. total charge of cations = total charge of anions. 2(1+) = 1(2-).

Explanation:

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

answer: good job it's all correct !
