Balancing a chemical equation is important because it shows the ratio of elements needed for the reaction to proceed properly. This allows scientists and researchers to use mathematical formulas to determine how much of one reactant is needed to produce the product.Continue Reading
When balancing a chemical equation, the Law of Conservation of Mass is used to determine that the same number of atoms of each element is present on each side of the equation. Atoms are counted by multiplying the subscript times the number in front of the molecule, atom or compound, which is known as the coefficient. The coefficient represents the ratio of the particular reactant or product, meaning how many times it is consumed or produced. In balanced equations, only whole numbers are used as coefficients. The coefficient or subscript is not written out if they equal 1.
Balanced chemical equations also include the state of matter that the reactants and products are found in. These can include gaseous, solid, liquid or aqueous. Aqueous compounds are usually ionic compounds. Ionic compounds have a special form of balanced equation called a net ionic equation that only includes the ions that react, disregarding reactants or products that remain unbonded or unchanged.Learn more about Chemical Equations
If a reaction is run at a constant temperature, T, the equation is delta G equals delta H minus T times delta S. This is the measurement of whether a chemical reaction is likely to occur with no additional energy input.Full Answer >
The balanced molecular equation for the reaction between KI and AgNO3 is written as KI + AgNO3 = AgI + KNO3. For an equation to be balanced, it must contain the same number of atoms on both its left and right sides.Full Answer >
The balanced chemical equation for cellular respiration is C6H12O6 + 6O2 -> 6CO2 + 6H2O, says Biology Web. This does not include the approximate 38 adenosine triphosphates in the equation, according to the Department of Physics and Astronomy at Georgia State University. This is also known as ATP.Full Answer >
Stoichiometry is a branch of chemistry that deals with the relationship between reactants and products involved in a chemical reaction. In other words, it deals with calculations of masses or volumes of relative quantities of elements involved in a chemical reaction.Full Answer >
