Calculate the mass percent of C in Freon-112 (C2Cl4F2).

elements make up everything, and they combine to make compounds.

the answer is c

i think tornado but not 100%

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.
