A chemical equation describes what happens in a chemical reaction. The equation identifies 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 refers to establishing the ...
Balance each of the following equations. Balanced equations. (Coefficients equal to one (1) do not need to be shown in your answers). 2.
Chemical equations are concise representations of chemical reactions. Reactants appear on the left side of the equation. Products appear on the right side of the equation. The states of the reactants and products are written in parentheses to the right of each compound. Coefficients are inserted to balance the equation.

Derive chemical equations from narrative descriptions of chemical reactions. Write and balance chemical equations in molecular, total ionic, and net ionic formats. The preceding chapter introduced the use of element symbols to represent individual atoms.
Chemistry 221 The Basics of Balancing Chemical Equations Step 1: Write the unbalanced equation using the correct chemical formula for each reactant and product. Keep organized and make a table underneath the reactants and products with the number of elements involved in the reaction. Step 2:
Balanced chemical equations. A balanced chemical equation is a representation of a chemical reaction using the chemical formulas of the reactants and products, and indicating the number of molecules or atoms of each substance.
Chemical equations are used to describe chemical reactions. The chemical symbols for the reactants are placed on the left-land side of the equation and the chemical symbols for the products are placed on the right-hand side. Either an arrow (→) or and equal sign (=) are used to indicate the reactants converting to products.
This chapter will describe how to symbolize chemical reactions using chemical equations, how to classify some common chemical reactions by identifying patterns of reactivity, and how to determine the quantitative relations between the amounts of substances involved in chemical reactions – that is, the
What happens when solutions of Ba(NO3)2 and Na2CO3 are mixed? NaNO3 is soluble; Cu(OH)2 is not.
