Why does the law of conservation of mass require that both sides of a chemical equation be balanced?

As compounds change under chemical reactions, there still will be the same number of atoms of each element in the end product. Say you start with 1-O2 molecule (Sorry I can't subscript) and 4-H molecules. You end up with 2-H2O molecules. Note that the O comes in pkgs (molecules) of two atoms, the H comes in pkgs of one atom. But altogether you start with 2-O atoms, if you split them apart, & 4-H atoms, already split apart. After the chemical reaction, you have 2-H2O molecules, containing a total of 2-O atoms and 4-H atoms. So the reaction would be 4-H + 1-O2 => 2-H2O. See?

∙ 11y agoThe law of conservation of mass says the mass in an enclosed system will remain constant over time - or in plain language, you can't destroy an atom. (This law was written before nuclear energy and nuclear bombs, which work by destroying atoms, were discovered.) So if you have 50 moles of carbon, 100 moles hydrogen and 50 moles of oxygen when you start out, and you do a reaction in an enclosed chamber, you will end up with a product that still contains that much of the three elements.

What is the number to the left to a chemical formula?
Balancing a chemical equation can often require a whole-number coefficient placed in front of a chemical formula. This upholds the Law of Conservation of Matter, which says that matter cannot be created or destroyed. These coefficients must be in the lowest possible ratio.
What is the balanced equation for the combustion of alkane in air?
The general equation isCnH2n+2 + (1.5n+0.5)O2 -> nCO2 + (n+1)H2OTechnically, that's only really balanced for odd n; for even n you need to double it.
What type of foods don't require chemical and physical digestion?
all foods require either physical or chemical digestion.
What scientific law is satisfied when balancing equations?
Law of Conservation of mass(atomic mass). As mass can be considered relative to energy, therefore Law of Conservation is also correct but Law of conservation of mass is is much more accurate because here mass is a much more accurate term that is required here. Here, since, we are balancing molecules, then we require atomic or molecular mass.
What are chemical reactions that require oxygen are described as?
iron
What is the coefficent that shows in a chemical equation?
Equations for chemical reactions may require one or more whole-number coefficients in order for the equation to balance. Balancing a chemical equation upholds the law of conservation of mass, which states that matter cannot be created or destroyed. The coefficients represent molar ratios of reactants and products. Performing stoichiometric calculations is largely dependent upon these correct molar proportions.

Does the US require a balanced budget?
No
Can three atoms of calcium react to produce six atoms of calcium?
No: That would violate the law of conservation of mass and require creation of new atoms, which no chemical reaction can achieve.
What is the chemical equation for LSD?
An equation would require a process... such as the equation for a specific step in the synthesis, which I doubt you where asking about. I'm assuming you mean the chemical name: 9,10-Didehydro-N,N-diethyl-6-methylergoline-8ß-carboxamide or the chemical formula: C20H25N3O
What is a balanced chemical equation for magnesium oxide?
Magnesium + oxygen --> magnesium oxide 2Mg (s) + O2 (g) --> 2MgO (s)

Is sodium a chemical equation?
No, because chemical equations require more than one element. For example: Na- + Cl -----> Na- Cl (Na is negative & Cl is positive) Also chemical equations have to have an arrow instead of an equal sign, as far as I know.
An accurate statement about achieving a balanced budget would be that?
most states require a balanced budget for state spending
What type of foods don't require chemical and physical digestion?
all foods require either physical or chemical digestion.
How go you get oxygen out of carbon dioxide?
The easiest way is photosynthesis, with the chemical equation: 6CO2 + 6H2O + ATP (Energy) --> C6H12O6 + 6O2 There are other methods, but they require large amounts of energy. Burning gas or coal does the opposite and produces large amounts of power. The opposite equation (breaking apart the elements instead of combining them) would require equal, if not more, power.
Chemical reactions that require energy?
endothermic reactions require energy
