Scientists always consider that whenever there is an experiment, there is a tendency for a decrease in the amount of the expected product. Is this result a violation of the law of
conservation of matter? Why or Why not?

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
