7.7 Mole Relationships in Chemical Equations
When the reactant that is reduced reacts with hydrogen, it forms a saturated hydrocarbon.
The Succinic acid Fumaric acid oxidation and reduction reactions of the iron ion in the cell's cyto are accompanied by a coenzyme, flavin adenine chromes.
A strong germicide is used to kill germs in swimming pools.
A mole-mole factor can be used to calculate the number of moles of another substance in a reaction.
The total amount of matter in the reactants is the same as the total amount of matter in the products.
The total mass of the reactants must be the same as the total mass of the products.
As original substances are changed to new substances, no material is lost or gained.
When silver reacts with sulfur to form silver sulfide, tarnish forms.
The mass of the reactants is the same as the mass of the product.
The number of silver atoms that react is more than the number of sulfur atoms.
100 sulfur atoms are required when 200 silver atoms react.
Many more atoms of both silver and sulfur would react in the chemical reaction.
The coefficients in the equation can be interpreted in terms of moles if we are dealing with silver and sulfur.
2 moles of silver react with 1 mole of sulfur to form 1 mole of Ag2S.
The moles of Ag, S, and Ag2S can be stated in grams of each because the molar mass of each can be determined.
There are 215.8 g of Ag and 32.1 g of S in this picture.
The mass of reactants is equal to the mass of product.
The product is iron(III) sulfide when iron reacts with sulfur.
The balanced chemical equation shows that 2 moles of iron react with 3 moles of sulfur to form 1 mole of iron(III) sulfide.
You need to know the correct amount of reactants to use and how much of the product will form if you want to prepare medicines in a pharmaceutical laboratory.
There are given and needed quantities.
To convert the given to the needed quantity, you have to write a plan.
Write mole-mole factors using coefficients.
Give the needed quantity by setting up the problem.
The number of moles of iron needed to react with sulfur is calculated using the equation.
The number of moles of another substance in the water is calculated using the chemical reaction of hydrogen with oxygen.
