How many oxygen molecules are produced when 89.5 g of mercury (II) oxide are allowed to decompose according to the following equation:
2HgO --> 2Hg + O,
2.48 x 1023 molecules
2.11 x 1023 molecules
1.24 x 1023 molecules
1.02 x 1023 molecules
6.02 x 1025 molecules

Count the number of each type of atom in the equation below, and then balance the equation. write in the numbers of atoms and coefficients. add a 1 if there should be no coefficient. cs2(l) + o2(g) → co2(g) + so2(g) c [ ] s [ ] o > c [ ] s [ ] o [ ] cs2(l) + [ ] o2(g) > [ ] co2(g) + [ ] so2(g)
