Determining the limiting reactant requires that all mass quantities first be converted to moles to evaluate the equation.
-
-
when two substances react to from products, the reactant which is used up is called limiting reacting (limit)
a chemical equation is balanced when the coefficients of the reactants equal the coefficient of the products
-
Mole ratios allow comparison of the amounts of any two materials in a balanced equation.
Calculations can be made to predict how much product can be obtained from a given number of moles of reactant.
Mass-mass calculations involve converting the mass of a reactant to moles of reactant, then using mole ratios to determine moles of product which can then be converted to mass of product.
Calculations of volume-volume ratios are based on Avogadro’s hypothesis.
Pressures and temperatures of the gases involved need to be the same.
Calculations are described for determining the amount of gas formed in a reaction.
Calculations are described for determining amounts of a material needed to react with a gas.
-
Theoretical yield is calculated based on the stoichiometry of the chemical equation.The actual yield is experimentally determined.he percent yield is determined by calculating the ratio of actual yield/theoretical yield.
to determine the limiting reactant in a chemical reaction one must know the available amount of each reactant
-
The chemical equation needs to be balanced so that it follows the law of conservation of mass. A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side. Balancing chemical equations is a process of trial and error.
If you have to write the chemical formula of a simple, binary ionic compound given the name of the compound, you follow a set of three steps. Let's go through them using magnesium chloride as an example. Write the symbols for the cation and the anion: Mg and Cl. Determine the charge on the cation and anion.
