The three fundamental laws of chemistry is the following:
A. Law of conservation of mass- mass is neither created nor destroyed during an ordinary chemical reaction or physical reaction.
B. Law of definite porportions- a chemical compound contains the same elemtents in exactly the same proportions by mass regardless of the sample of the source of the compound.
C. Law of multiple proportions- if two or more different compounds are composed of the same two elements, then the ratios of the masses of the second element, combined with a certain mass of the first element is always a ratio of small whole numbers

What is a scientific reaction?
A scientific reaction is a process in which one or more substances are changed into one or more new substances through the breaking and forming of chemical bonds. These reactions follow the laws of physics and chemistry and can be described by balanced chemical equations.
How do pure substances combine?
Pure substances combine to form new substances through chemical reactions. During a chemical reaction, the atoms of the pure substances rearrange to form new chemical bonds, leading to the creation of different compounds with unique properties. The process is governed by the laws of conservation of mass and energy.
In what sense does chemistry underlie physics?
Chemistry serves as the foundation for understanding many physical phenomena. Through the study of chemical reactions and the behavior of atoms and molecules, chemistry provides important insights into the underlying principles of physics, such as quantum mechanics and thermodynamics. In essence, chemistry provides the microscopic framework that underlies the macroscopic laws of physics.
Examples Answers calculate k1 and k2 in parallel reactions?
To calculate the rate constants k1 and k2 for parallel reactions, you can use the rate laws for each reaction and the experimental data. Typically, you would perform experiments at different initial concentrations of reactants for each reaction and use the integrated rate laws to determine the rate constants. Kinetic data analysis software or graphical methods like the method of initial rates can also be utilized to determine the rate constants for parallel reactions.
Scope of organic Chemistry?
Physical Chemistry is the study about atomic, subatomic, macroscopic, and particulate development in the chemical system by the terms of physical laws and concept. Physical Chemistry has a huge scope; some of the scopes are acids, bases, quality and control, reactions, buffers, and micrometrics.
Do chemical reactions describe laws of conservation?
Chemical reactions respect the law of mass conservation.

Will all the chemical reactions are obey thermodynamics law?
No one has yet documented a case where a chemical reaction does not obey the laws of thermodynamics - so - yes - all the chemical reactions will obey the laws of thermodynamics. On a philosophic note: since no exceptions to the theories that constitute thermodynamics have been observed, we consider them "laws". Should we ever find an exception, we will have to modify the theories to craft new rules that will then be considered "laws". That's how science works.
