Question

State the law of definite proportions and explain.​

Answer 1

According to the Law of Definite Proportions, a chemical compound will always include the same weight proportions of each element, regardless of the quantity or source.

Step-by-step explanation:

For instance, 21.5 grams of carbon and 28.5 grams of oxygen make up a 50-gram sample of carbon monoxide.

Answer 2

Answer: The law of definite proportions states that a given chemical compound always contains the same elements in the exact same proportions by mass

Explanation: The discovery that mass was always conserved in chemical reactions was soon followed by the law of definite proportions, which states that a given chemical compound always contains the same elements in the exact same proportions by mass. As an example, any sample of pure water contains 11.19% hydrogen and 88.81% oxygen by mass. It does not matter where the sample of water came from or how it was prepared. Its composition, like that of every other compound, is fixed.

Another example is carbon dioxide. This gas is produced from a variety of reactions, often by the burning of materials. The structure of the gas consists of one atom of carbon and two atoms of oxygen. Carbon dioxide production is of interest in many areas, from the amount we breathe to the amount of the gas produced by burning wood or fossil fuels. By knowing the exact composition of carbon dioxide, we can make predictions as to the effects of different chemical processes.

I hope this helps :)
