Why do scientists have to make sure chemical equations are balanced?

∙ 13y ago
Balancing a chemical equation establishes what proportions of the reactants are required for complete reaction as well as the proportions of the products of the reaction. Some factors in balancing the equation will also dictate what the products ARE. For example - when balancing the equation for a combustion reaction, the presence of nitrogen in the fuel molecule will yield certain products while it's absence will exclude certain products. Likewise, when performing electrochemical reaction balances, balancing the electrochemistry will dictate the products of the reaction.

How would you use the word conservation of mass in a sentence?
The Law of Conservation of Mass means that chemical reaction equations must be balanced, otherwise you have lost or gained matter out of nowhere.
What are the advantages of chemical equations?
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.
How do you use the word chemical equation in a sentence?
To correctly determine the balanced chemical equation, one must make sure that the products are appropriately relating to the reactants and make sure that the equation is balanced with the lowest coefficients.
How the chemical equations for the synthesis of methyl orange?
Please rephrase your question. It doesn't make sense. Do you mean, "What are the chemical equations for the synthesis of methyl orange?", "How is methyl orange synthesized?", or are you trying to figure out the mechanism?
Why is net ionic communicate more than chemical equations?
The net ionic equations only represent the substances that make a change in the oxidation numbers, whereas a chemical equation shows all substances even they do not differ during the reaction.
How does facts help scientist?
Scientists make theories or equations that are not proved. Facts prove or disprove the theories or the equations. Note: -Some theories or equations can't be proved or disproved by facts so they are proved or disproved by the majority of scientists.

To correctly determine the balanced chemical equation, one must make sure that the products are appropriately relating to the reactants and make sure that the equation is balanced with the lowest coefficients. That should help.
What are the advantages and disadvantages of equations?
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
Can you live in water?
If youre an amphibian yes. if youre a human no unless the scientists make up some chemical that can make a human live in water. I heard the agency's keeping a secret about the scientists trying to make a chemical to live in water.

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
