In chemical reactions mass is doubled
Web4. In a chemical reaction, mass is conserved. This means that a) The mass of the reactants stays the same during a chemical reaction b) The mass of the products stays the same during a chemical reaction c) The type and number of atoms in the reactants equals the type and number of atoms in the products WebThese double replacement reactions occur when an acid and a base react to make a salt and water. HA + BOH → BA +H 2 O HNO 3 (aq) + NaOH (aq) → NaNO 3 (aq) +H 2 O (I) For today’s experiment you will classify reactions as one of the main 5 types of chemical reactions. Then you will further categorize it as a specific type of aqueous reaction.
