In a calorimetery experiment, a researcher may burn a sample of food, which heats a sample of water. This procedure illustrates which energy transformation

i would say b

explanation:

but i think i would need more information than that

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.
