Look at many kinds of evidence that chemists use to see if a chemical change has. Introduction: It is important to distinguish chemical changes, in which new substances areįormed, from physical changes, which do not create new substances. The white precipitate also indicates that a chemical changeĬlick Reset. Do you think a chemical reaction has taken place? Explain.Ī chemical reaction has occurred since there was production of gas when sodium Sodium is a metal so softĪn explosive reaction occurs and a gas is produced. To begin, check that Reactant 1 is Sodium and Reactant 2 is Water. Will look for evidence of chemical changes by looking at More substances, called reactants, are transformed into different Vocabulary: chemical change, coefficient, conservation of matter, decomposition, dissolve,ĭouble replacement, endothermic, exothermic, ion, physical change, product, reactant, singleĪ chemical change, (or chemical reaction) occurs when one or
