Caulk or seal behind baseboards and in cracks and crevices where centipedes like to hide. Place a dehumidifier in damp areas to sufficiently dry the air. Structural repairs may be necessary to the home and/or yard if a dehumidifier does not keep a room sufficiently dry.
Hydrogen chloride is a colorless to slightly yellow gas with a sharp, irritating odor. It forms a dense white vapor when it comes in contact with air. When hydrogen chloride dissolves in water, it forms hydrochloric acid also known as muriatic acid.
Masters degree with Distinction from Imperial College London, first degree in Chemistry from University of Central Lancashire. Zinc + Hydrochloric acid is a basic metal acid reaction. When the Zinc is added to the acid, the zinc dissolves and reacts with the acid, forming hydrogen gas and the salt Zinc Chloride. These sorts of reactions (metal + acid) will always result in a salt (in this case, zinc chloride) and hydrogen gas. The observations from this experiment would be white-gray solid is added to colorless liquid. Solid dissolves and a colorless, odorless gas is formed.
