Three versions:(1) Clarify the phenomenon that carbon dioxide gas Ca (OH)2+CO 2→CaCO 3 H 2O (double decomposition) is introduced into lime water: lime water changes from clarification to turbidity. Relevant knowledge point: This reaction can be used to test the existence of carbon dioxide gas. Magnesium belt burns in air 2Mg+O 2 phenomenon: It emits dazzling white light.
