What method do you use to balance a chemical equation?
PARTIAL EQUATION METHOD:----- When equations contain many reactants and products they cannot be balanced by the hit and trial method. They are then balanced by the partial equation method. In this method the overall reaction is assumed to take place through two or more simpler reactions, which can be represented by partial equations. The steps involved are: Steps and problem * The given chemical equation is split into two or more partial equations. * Each partial equation is separately balanced by the hit and trial method. * These balanced partial equations are multiplied with suitable coefficients in order to exactly cancel out those common substances which do not appear in the overall chemical equations. * The balanced partial equations so obtained, are added to arrive at the balanced chemical equation. PROBLEM Balance the equation, NaOH + Cl2---------------------------------> NaCl + NaClO3 + H2O by partial equation method. SOLUTION The given skeleton equation can be split into two partial equations. Partial eq.1 NaOH + Cl2---------------------------------> NaCl + NaClO + H2O Partial eq.2 NaOCl ------------------------------> NaCl + NaClO3 The two partial equations are balanced by hit and trial method. Balanced partial eq.1 2NaOH + Cl2---------------------------------> NaCl + NaClO + H2O Balanced partial eq.2 3NaOCl ---------------------------------> 2NaCl + NaClO3 NaClO does not appear in the overall equation and so to cancel it, the partial balanced equation 1 is multiplied by 3 and the two equations are added to get the overall balanced equation. 2 NaOH + Cl2---------------------------------> NaCl + NaClO + H2O * 3 3NaOCl ---------------------------------> 2NaCl + NaClO3 FINALLY 6NaOH + 3 Cl2---------------------------------> 5NaCl + NaClO3 + 3H2O
What is the purpose of a chemical equation?
I don't remember all of the mathematical names, but I do remember that you need to balance equations so that both sides will be equal. These are very simple examples but they will show you that balanced equations are equivalentto being equal.Such as: (2+2)=4=(3+1) Both sides equal '4'.Differing equations on opposite sides of the equal sign demonstrate that are differing ways to express a certain figure.Or: (2+6)-(3x1)=5=(2x2)+(4-3) Here both sides equal '5'.(8) - (3) =5= (4) + (1)Hope this helps.
How to solve chemical equations?
:A balanced equation MUST have EQUAL numbers of EACH type of atom on BOTH sides of the arrow.An equation is balanced by changing coefficients in a somewhat trial-and-error fashion. It is important to note that only the coefficients can be changed, NEVER a subscript.
What is a sentence for the word alchemy?
Early experimenters with alchemy were able to create chemical compounds by trial and error.The Wizard used his alchemy to bring to back to health.
What is the purpose of trial run?
No
What is true about balancing chemical equations?
Single atoms should be done last Balancing chemicals equations involves trial and error
Why is trial and error so useful in math?
There are many equations for which there is no method for obtaining an exact solution. In such circumstances, an efficient trial and error method may be the only way.

Who discovered trial and error method?
humans
Does a balancing trial balance mean that all accounting principles you applied?
Not necessarily, just because it balances it can still be wrong.
