Lavoisier proposed that all matter is composed from the same elements.

Explanation: -

Lavoisier was a french chemist. He was a pioneer of stoichiometry. He proposed that all matter, irrespective of the physical state, is composed from the same elements.

Thus water, ice and water vapor all have the elements hydrogen and oxygen in the same ratio 2:1.

Lavoisier also was the one who defined the element as something which cannot be further broken down into simpler substances by any chemical means.

well in order to answer this question you have to provide more information < 3

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.
