Every day 3 points, a total of 45 points) 1. (2011 Jinan simulation) of the following statements is not true (). The basic research program A. the properties of chlorine: to predict the nature, to observe the appearance of the experiment and the observation, explanation and conclusion B. solution, if the water bottle exceeds the capacity scale line, available dropper will suck excess solution C. chlorine, ammonia and hydrochloric acid are capable of conducting, but not the electrolyte D.Na2O, Na2O2 elements is the same, but not the same with the reaction product of CO2 [analysis] B. Study on the properties of Cl2 basic procedures in line with the basic procedures for studying the properties of materials, to observe the characteristics of the material appearance and material properties, prediction of experimental observation, interpretation, A; solution, if the water over the scale line, can not be sucked out by excess solution dropper, should be re prepared, B was wrong; it is a mixture of hydrochloric acid, ammonia, and C are not correct; Na2O electrolyte and CO2 reaction produces only Na2CO3, Na2O2 and CO2 reaction not only generate Na2CO3, also generate O2, so the product is different, D is right.
