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:

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
