if 5.50 L of water vaporat 50.2 °C and 0.121 atm reacts with an excess of iron to produce iron(III)oxide and hydrogen gas, how many grams of iron(II) oxide will be produced? Enter your answer as a numerical value with no units.

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
