Let every man prove his own work, and then shall he have rejoicing in himself alone and not in another, according to the bible, we should all be rejoicing in the work that we do, with our hands, this is why it is imperative, that we stay busy and never stop doing good work.
In today’s article, we are going to talk about the observations, which led to an atomic view of matter.
The law of mass conservation, the law of definite or constant composition and the law of multiple proportions, are the extremely important chemical observations, which were established in the 18th century.
The law of mass conservation, was the most important and fundamental chemical observation of the 18th century.
The law of mass conservation states that during a chemical reaction, the total mass of substances, does not change.
The total amount of matter in a substance, does not change, although by definition, the number of substances may change, and their properties must change.
On the basis of the combustion experiments, Lavoisier, had first stated the law of mass conservation.
Lavoisier’s experiment showed that the mass of oxygen and mercury, was equal to the mass of mercuric oxide, formed by oxygen and mercury.
By observing that the mass of any two elements, didn’t change before and after a chemical reaction, scientist were able to establish the law of mass conservation.
The main purpose of the law of mass conservation, is to demonstrate that matter cannot be created nor destroyed.
All right now, let’s talk about the law of definite or constant composition and see what this means.
The law of definite or constant composition, is indeed another fundamental chemical observation, which has led many scientists to view matter at an atomic level.
The law of definitive or constant composition, states that, a particular chemical compound is composed of the same elements in the same parts or fractions by mass, no matter the source of the chemical compound.
The part of the compound’s mass contributed by the element is known as the fraction by mass or mass fraction; which is also obtained by dividing the mass of each elements in a compound by that of the total mass of the compound.
Another observation which led to an atomic view of matter, is known as the law of multiple proportions.
The law of multiple proportion is a phenomenon described in John Dalton’s atomic theory, which occurs when two elements, form more than one compound.
The law of multiple compounds states that if elements A and B react to form two compounds, the different masses of B that combine with a fixed mass of A can be expressed as a ratio of small whole numbers.
The mass fraction of one element relative to another element changes in increments based on ratios of small whole numbers, in two compounds of the same elements; according to the law of multiple proportions.
We are able to explain the compositions of carbon oxides on the atomic scale, thanks to< b> the law of mass conservation, the law of definite or constant composition and the law of multiple proportions.
