Final answer:
The compounds CO, CO2, and C2O3 adhere to the law of definite proportions, law of multiple proportions, and law of conservation of mass. These laws refer to the consistent proportions of elements in compounds, the ratios in which elements can combine to form different compounds, and the principle that mass cannot be created or destroyed in a chemical reaction.
Step-by-step explanation:
The molecules CO, CO2, and C2O3 follow all of the laws you've mentioned; the law of definite proportions, the law of multiple proportions, and 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 pure compound contain the same elements in the same proportions by mass. For example, every sample of water (H2O) will always have two atoms of hydrogen (H) for every one atom of oxygen (O), maintaining a constant proportion.
The law of multiple proportions states that when two elements react to form more than one compound, a fixed mass of one element will react with masses of the other element in a ratio of small whole numbers. To illustrate, carbon (C) can react with oxygen (O) to produce CO or CO2. In CO, the ratio of carbon to oxygen is 1:1. In CO2, the ratio is 1:2, but in terms of whole numbers, both ratios follow the law.
Finally, the law of conservation of mass affirms that mass cannot be created or destroyed in a chemical reaction. This means that the total mass of reactants in a chemical reaction will always be equal to the total mass of the products.
