Balance the following chemical equation:
(?) Al +(?) O2 >(?)Al2O3

If two objects at different te, peraure are in contact with each other what happens to their temperature

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)

As changes in energy levels of electrons increase, the frequencies of atomic line spectra they emit
