The balance equation for Chromium (III) oxide with dilute hydrochloric acid is Cr2O3(s) + 6HCl(aq) ---> 2CrCl3(aq) + 3H2O(l).
A chemical equation describes what occurs in a chemical reaction. The equation classifies the reactants (starting materials) and products (resulting substance), the formulas of the participants, the phases of the participants (solid, liquid, gas), and the amount of each substance. Balancing a chemical equation denotes to establishing the mathematical relationship between the quantity of reactants and products. The quantities are expressed as moles or grams.
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge are the same for both the reactants and the products. In other words, the charge and the mass are balanced on both sides of the reaction. Balanced equation is also known as balancing the equation, balancing the reaction, and conservation of charge and mass.
It takes practice to be able to write balanced equations. There are essentially three steps to the process: write the unbalanced equation; balance the equation; and indicate the states of matter of the reactants and products.
Three U.S.-based scientists won a Nobel Prize recently for developing a powerful new way to do chemistry on a computer. They pioneered highly sophisticated computer simulations of complex chemical processes, giving researchers tools they are now using for a wide variety of tasks, such as designing new drugs and solar cells.
