These reactions produce salt, water and carbon dioxide. I will leave you to determine the "products.". Sulfur compounds are invoked as the likely colouring agents because sulfur is relatively abundant in the cosmos and hydrogen sulfide is notably absent . That means that each substance ionizes 100% to give this total ionic equation: Everything is identical on each side of the arrow, so everything is eliminated for being a spectator ion. Let's start by writing a complete molecular equation: 3) Eliminate spectator ions to get the net ionic: However, nothing tells you to eliminate sodium ion until you actually do the problem. Problem #41: What is the balanced chemical equation for: liquid phosphoric acid reacting with aqueous barium hydroxide to produce a precipitate of barium phosphate and liquid water. Repeat this procedure quickly with a second wad of cotton wool and hydrochloric acid. Where the two gases mix, you get a white smoke of solid ammonium chloride.
