For ex: 6HNO3+ S - H2SO4+ 6NO2+ 2H2O Non-metals will normally not react with water, however, non-metal oxides will react with water to form acids. Why Should You Emphasize On Heart and Brain Health? Name the metal which reacts with a very dilute HNOs to evolve hydrogen gas. Some are highly reactive with many compounds, some only react with certain compounds and others hardly react at all. Alkali metals and halogens are the two most reactive classes of elements due to their valence electrons.
