In this experiment, tin calx (which is now known as tin oxide) is the product of the reaction which he showed that it consisted of the tin together with a portion of the air. (2) Another experiment done by Lavoisier was on red mercury compound in which he bowled the former in a sealed apparatus. After the reaction has occurred, aside from the formation of oxygen gas, the red mercury became silvery liquid. Lavoisier confirmed by weighing the apparatus that the chemical species were the same in quantity before and after the experiment (Zinni).
The second principle (atoms are neither created nor destroyed in chemical reactions) supports the law of conservation of mass. Since atoms are present in all matter, then this principle by Dalton truly explains the law of conservation of mass.
The law of definite proportions (also known as the law of constant composition) states that all samples of a particular compound have the same composition – the same proportions by mass of the constituent elements (wiseGEEK).
Joseph Proust discovered this law when he was conducting some experiments that involved the determination of chemical formulas. Most of his experiments were done primarily on metal compounds (the very common one is on oxides of copper). He reacted several elements with oxygen and he found out that amount of oxygen in the product from these reactions was always fixed at one or two values. Another experiment of Proust that led to the discovery of the law of definite proportions was on copper (II) carbonate. Proust showed that this compound always had 5.3 parts copper to 1 part carbon to 4 parts oxygen (Joseph Louis Proust).
