The number of atoms in the reactant and products must be equal to obey the law of conservation of mass.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.

Rules of balancing chemical equations:1. write the unbalanced equation2. count the number of atoms of the same element on reactant and product side of equation3. make the number of atoms the same by changing the coefficients, not subscripts4. balance hydrogen and oxygen last5. reduce coefficients if possibleThe first step in balancing a chemical equation is identifying all elements.For example:H2OSo the elements you would identify are H (hydrogen) and O (oxygen).--------------------------------------------------------------------------------------------------------b. identify the reactants and products. - (e2020)
True
All properly balanced chemical equations fit that criteria: they must have the same number of atoms of each element on each side of the "yield" arrow. Balancing an equation can be achieved by using whole number coefficients as needed. This upholds the Law of Conservation of Mass, which states that matter cannot be created or destroyed.
The key to using the elimination method is to find variable terms in two equations that have unequal coefficients

Well chemical equations can help us understand how a certain substance is made and what combines with what to make it using symbol and word equations .It makes more understanding of the concepts through symbols.
Symbol equations for reactions are written using chemical formulae.
Well chemical equations can help us understand how a certain substance is made and what combines with what to make it using symbol and word equations but if you dont know your elements it can be a problem
Writing a chemical reaction with symbols: Ex.: NaCl + AgNO3 = AgCl (s) + NaNO3 A mathematical (digital) system for the writing of chemical equations exist but it is rarely used.
Eliminate the variables that have equal coefficients but opposite in sign.x + 2y = 103x - 2y = 14Or you can work to have one of the variables with equal coefficients but opposite in sign such as:3x + 2y = 5x + y = 2 multiply by -2 to both sides3x + 2y = 5-2x - 2y = -4
In that case, it may, or may not, be possible to factor it using non-integer coefficients.
