Derive chemical equations from narrative descriptions of chemical reactions. Write and balance chemical equations in molecular, total ionic, and net ionic formats. Balance the following simple equations : C + O 2 CO N 2 + O 2 ⇌ NO ZnS + O 2 ZnO + SO 2 Al + O 2 Al 2 O 3 Mg + N 2 Mg 3 N 2 Al + N 2 AlN NO + O 2 NO 2 SO 2 + O 2 ⇌ SO 3 H 2 + Cl 2 HCl Fe + Cl 2 FeCl 3 H 2 S + Cl 2 S + HCl FeCl 2 + Cl 2 FeCl 3 CO 2 + C CO KHCO 3 K 2 CO 3 + H 2 O + CO 2 K + CO 2 K 2 O + C Balancing chemical equations involves the addition of stoichiometric coefficients to the reactants and products. This is important because a chemical equation must obey the law of conservation of mass and the law of constant proportions, i.e. the same number of atoms of each element must exist on the reactant side and the product side of the equation. Two quick and easy methods of balancing a chemical equation are discussed in this article. The first method is the traditional balancing ... Enter a chemical equation and press the Balance button to get the balanced equation and the type of reaction. Use uppercase for the first character in the element and lowercase for the second character.
