a. Write a balanced equation for reaction of iron with oxygen gas to form iron (III) oxide.
b. When 15.0 g of iron are reacted, how many moles of oxygen are consumed?
c. If you want to form 254 g of iron (III) oxide, how many grams of iron are needed?
All chemical reactions are represented by chemical equations by using formule of reactants and products
Qualitatively a chemical equation simply describes what the reactants and products are
However a balanced chemical equation gives us a lot of quantitative information mainly the molar ratio in which reactants combine and the molar ratio in which products are formed.
A balanced chemical equation is one which contains an equal number atoms of each element on both sides of equation
