Why does the sum of the coefficients on the reactant side of a balanced equation does not have to equal the sum of the coefficients on the product sum of the equation?

The requirement for a balanced equation is that the numbers of each kind of atoms in the reactants must match the number of each kind of atoms in the products. The number of atoms in each molecule in the equation is the product of the coefficient and the subscript affixed after each element symbol in the formula to which the coefficient applies. For example, 2 Na + Cl2 = 2 NaCl. The coefficients on the left side total 3 but those on the right side total only 2. However, the number of atoms of each of sodium and chlorine total 2 on each side.

What can the coefficients in a balanced chemical equation always express the ratio of?
Moles of one substance compared to moles of the second substance. Ex. moles of reactant A compared to moles pf product F
What is a mole ration?
I think you mean mole ratio. It is usually represented as the coefficient or big number in a balanced chemical equation. N2 + 3H2 --> 2NH3 so the mole ratio of nitrogen to hydrogen is 1 : 3 or 1/3 and what you compare should be product / product or reactant / reactant
Which do you use to balance equations subscrips or coefficients?
Both. you must have the correct subscripts to represent the correct chemical then you only change the coefficients to balance the equation. The product of a coefficient and a subscript tells how many atoms are present.
What is produced in this equation Li2Os H2OI 2LiOHaq?
Lithium oxide, and water are the reactants. Lithium hydroxide is the product. Here is the balanced reaction equation. Li2O(s) + H2O(l) = 2LiOH(aq)
What is the equation for average product?
the total product divided by quantity
What gets written into a chemical reaction when it is balanced?
In a complete and correctly balanced chemical equation you will have the coefficients for each reactant and product indicating the mole ratios as well as the phases of each reactant and product.
How do you find out how many moles of lead will be produced from a limiting reactant?
Knowing the limiting reactant, ignore other reactants and calculate the product (lead) based on just that one reactant using the coefficients of the balanced equation.
The numbers which are placed in front of each reactant and product in order to balance the equation are called?
Stoichiometric coefficients.
What can the coefficients in a balanced chemical equation always express the ratio of?
Moles of one substance compared to moles of the second substance. Ex. moles of reactant A compared to moles pf product F
What is a chemical equation in which both the reactant an product have an equal number of atoms of a given element?
balanced equation
An equation is balanced when .?
the number and type of atoms of reactant and product are the same
What is a chemical equation in which both the reactant and product have an equal number of atoms of a given number?
balanced equuation A+
How is stoichiometry used to calculate amount of product from amount of reactant?
The coefficients give the ratio of moles reactant to moles product.
What is the water equation?
In order to have a balanced equation, adding the reactant H2 And O2 (H2+O2) have to come out equal on the product side and the reactant side. This would look like H2+O2 = H2O2
What determines the coefficient ratio used to predict the amount of product produced from any given amount of reactant?
The reaction equation gives the RATIO of moles reactant to moles product. With known molar mass the (mass) yield can be calculated. (Of course other reactants are to be in excess! for complete reaction of the reactant involved for this yield)
How can balenced equations be used to calculate the volume of gases formed in chemical reactions?
The coefficients in a balanced chemical equation shows how many moles of each reactant is needed in order for a reaction to take place. After determining how many moles of each reactant is required, you would convert it to grams to calculate how much of each reactant is needed to form a given amount of product in a chemical reaction.
What does a chemical reaction show?
It shows the preservation of mass and of matter.
