What else can I help you with?
What two types of scientific. knowledge can be expressed. as mathematical equations?
Laws is one... and the other one i dont know... :SLaw and making models.
What law of chemical change is followed in balancing chemical equation?
The laws of conservation of mass and of numbers of each type of atom.
What are the four physical quantities that are conserved?
While there are many more (somewhat more obscure) conservation laws throughout physics (like "Conservation of Lepton Number"), I believe the four you may be referring to are Conservation of Matter Conservation of Energy Conservation of Charge Conservation of Momentum NOTE that Conservation of Matter is not a true law (it is broken in many nuclear reactions). The other three are laws.
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.
Why did scientists believe in a neutrino long before it was detected?
This was because of laws of conservation of: momentum, angular momentum, and energy. In certain reactions, these were apparently not conserved; a hypothetical particle would resolve the observed discrepancy.This was because of laws of conservation of: momentum, angular momentum, and energy.

Laws of chemical composition?
The laws of chemical composition are fundamental principles in chemistry. The Law of Definite Proportions states that compounds always have fixed proportions of elements by mass. The Law of Multiple Proportions describes how elements can combine in different whole-number ratios to form distinct compounds. The Law of Conservation of Mass asserts that mass is conserved in chemical reactions. Avogadro's Law states that equal volumes of gases at the same temperature and pressure contain the same number of molecules. These laws underpin our understanding of chemical reactions and the behavior of matter, forming the basis for stoichiometry and helping predict and describe chemical outcomes.
What are the three laws governing chemical reactions?
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 numbersbln
Why would the name Law of Conservation of Atoms would be an equally valid name?
The name "Law of Conservation of Atoms" would be equally valid because it emphasizes that during a chemical reaction, atoms are neither created nor destroyed; they are simply rearranged to form new substances. This highlights the fundamental principle that the total number of atoms remains constant, reinforcing the conservation concept. By focusing on atoms specifically, the name underscores the microscopic basis of chemical processes, which is crucial for understanding reactions at the molecular level. Thus, it aligns with the broader conservation laws in physics and chemistry.
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.
What are the conservation laws of nuclear reactions?
Please anyone tell me answer I need it thanks
When wood is burned a lot of energy is produced. Is the conservation of energy law applicable in this case?
Conservation laws are in force when a candle burns. Chemical changes occur in the materials involved in the burning, but all the atoms in the candle and the air (which supplies the oxygen needed for burning) are present in the byproducts of combustion. Nothing is lost. Chemical bonds are broken when a candle burns, and chemical energy in the molecules in the wax or paraffin is converted into thermal energy (heat) and released. But nothing is "lost" in the reaction and conservation laws are not broken.
