The law of conservation of matter states that during a chemical reaction, the amount of matter
a) increases.
b) decreases.
c) disappears.
d) stays the same.

Option (D) is the correct answer.

Explanation:

Law of conservation of matter states that mass of an object never changes with time. This means that during a chemical reaction mass of reactants remains the same even after the formation of products.

Thus, we can conclude that the law of conservation of matter states that during a chemical reaction, the amount of matter stays the same.

According to Lavoisier, in a closed system, the total mass of the substance before the reaction will be the same as the total mass of the substances produced by the reaction.

substance mass of reagent = mass of product substance

Lavoisier experimented by reacting mercury and oxygen to the closed space to produce mercury oxide

And when heated, this mercury oxide will produce the same amount of oxygen and oxygen in the initial conditions

From here, he finally put forward the conservation law of the masses, namely:

In a closed system, the total mass before the reaction will be a total mass reaction.

In general, the reaction takes place in the open air. If the reaction results from combustion, the mass of reaction will be smaller than the original mass. Or if the reaction binds to a larger than the environment then the reaction will be greater than the original mass.

For example, in a paper combustion reaction is a mass of paper that is burned because there is a gas released into the water

quantum mechanics or quantum physics is physics of very small objects (particles) and physical entities.

quantum physics has some parallels to our macro world and some pretty unique ideas which theoretically and mathematically proven to be true even though we will never be able to access them because of our size.

there are many types of particles: subatomic, elementary etc.

subatomic means they are smaller than atom, elementary means they are at the very basis of everything.

subatomic particles are for eg. protons, neutrons but not electrons.

elementary particles are categorised into 3 groups by what they do.

these 3 groups are quarks, leptons and bosons.

light for example is a particle more precisely a photon a part of leptons.

proton (subatomic particle) is made out of 2 up quarks and 1 down quark each of these has a fractional charge like . (i crazy)

most famous scientist who contributed to this physics are:

the topic itself us understand a lot and will probably be vastly used in the future (quantum computers, understanding the big bang,

we also must not forget quantum effects like:

and there is more. but probably too much for this answer to be consistent due to my average understanding of this topic.

hope this you understand quantum mechanics a little more. i'm not an expert in the topic (so don't be like wth if you are an expert) but i'm very interested in it.

anyways quantum physics is a very hard topic (harder than physics (perhaps)) therefore searching for every information there is about it and learning it is unfortunately impossible (you can only specialise into 1 - 3 things or more (perhaps

have fun and i wish you luck!
