A typical acid-base reaction will produce an ionic compound called a salt and water. Answer: Chemical equations speak for the products of the reactions and how they are formed. For example, the equation for the combustion reaction of propane, found in gas grills and some fireplaces, is: C3H8 + 5O2 4H2O + 3CO2 + energy Rust Alex See Figure2.1. These chemical properties can lead to the discovery of unknown specimens and explain how different types of matter react with each other. Simply stated, a chemical reaction is the process where reactants are transformed into products. The arrow sign () pointing towards the right-hand side is used to separate reactants and products. Chemical equations speak for the products of the reactions and how they are formed. An example of a redox reaction is the reaction between hydrogen gas and fluorine gas: \[H_2 (g) + F_2 (g) \rightarrow 2HF (g) \label{redox1}\]. The reaction vessel would be our mixing bowl. Real life example: The cut surface of an apple turns brownish after exposed to the air for a while. The number of atoms of each element must be equal on both sides of the equation. Mathematicians use their expertise to solve complex problems and to develop new and improved methods of doing so. Example 3 Ca (OH) 2 + H 3 PO 4 ---> Ca 3 (PO 4) 2 + H 2 O Answer There are three calciums on the right but only one on the left, and the calcium is in a single chemical species on each side .
