Is it true if the sum of the stoichiometric coefficients on one side of the equation will always equal the sum of the stoichiometric coefficients on the other side?
C6H12O6 + 6O2 -> 6CO2 + 6H2O 7 ( implied one in front of the carbohydrate glucose ) does not equal 12, so not true Only the sum of the atoms must be equal.
When using synthetic substitution with 1 why do the coefficients sum to the answer who discovered this?
The reason is because when you multiply by the number 1 you're not changing the other number at all, so using synthetic substitution with 1 just gets you adding the first to coefficients first, then the sum of that and the next one, and so on.
What are the Rules for subtracting radicals?
similar-a similar radicand is to add or subtract similar radicals we simply add and subtract there coefficients and Anex to the sum of their common radical part.
What are coefficients in chemistry?
coefficients is the power the number is raised to
What operations are associated with coefficients?
Identify which mathematical operations are associated with coefficients?
When aluminum oxide Al2O3 is formed as the only product from aluminum and molecular oxygen the sum of the coefficients on the reactant side is?
7
How is stoichiometry used to calculate amount of product from amount of reactant?
The coefficients give the ratio of moles reactant to moles product.
How do you make the reactant and product have the same amount of atoms?
You place coefficients in front of the chemical formulas.
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.
Are Chemical equations are balanced by changing the subscripts of the molecules?
ABSOLUTELY NOT Change the coefficients on reactant or productt units.
The numbers which are placed in front of each reactant and product in order to balance the equation are called?
Stoichiometric coefficients.
What is the sum of the coefficients of these terms3a + 4b + 5c?
12
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.
What indicates how much of each reaction will be used up in a reaction?
Probable "each reaction" is each reactant; coefficients are used.
How can one Tell how much of a reactant will be used in a reaction?
The ratio of the coefficients tells the ratio of moles of reactants used in the reaction.
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.
Is it true or false when adding coefficients I can only add them to the beginning of a chemical formula or element.?
This is true. Never change the subscripts, because that changes the substance. You use coefficients to indicate the amount of each reactant and product.
