During endothermic reactions
Did you know?
WebEndothermic Reaction is a chemical reaction in which the reactants absorb the heat energy from the surroundings in order to form different products. These reactions create a cooling effect, as they lower the temperature of their surrounding areas. An example of endothermic physical reactions is the melting of ice cubes as they absorb heat from the … WebThe reactions and types of reaction involved are: Sodium hydroxide + hydrochloric acid → sodium chloride + water (Neutralisation) NaOH (aq) + HCl (aq) → NaCl (aq) + H 2 O (l) …
