How much energy is given off by the following reaction, if 162.5 g of oxygen reacts with 216.7 g of ammonia (NH3)? 4 NH3 + 5 O2 à 4 NO + 6 H2O DH = -1225.6 kJ

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
