Synthesis is really just the flipside of predicting products. In any reaction, there are three groups of chemicals involved: the starting problems can be easy (if they are only one step) or they can be difficult (if they are more than one step).David R. Klein - - ‎Science. I can predict the products of chemical reactions in writing complete chemical equations. (synthesis demonstrate how to solve example problems of predicting reaction products (see pages ) challenging for Honors Chemistry. If you discover that it's tough to balance a reaction it is most likely because your formulas are incorrect. Predicting Products of Chemical Reactions This.

This text is a chemistry problem solving resource appropriate for teachers and their students who are enrolled in high school Advanced Placement Chemistry or in a first-year college General Chemistry course. The book incorporates a chemistry problem solving plan, one that uses an innovative graphic organizer strategy.

The strategy - successfully evaluated with students - combines problem solving processes with chemical concepts that will allow students to solve the most common and difficult problems encountered in the first year of chemistry.

Topical problem solving will focus on limiting reactant stoichiometry, identifying types of chemical reactions, equilibrium, acid-base equilibria, and electrochemistry. Why would this resource be of interest to chemistry students? To be successful to get into a well known college, medical school, physical therapy or graduate program often requires that students get an "A" in your pre-requisite Introductory General Chemistry course. To make matters worse, many college professors feel that only a few students should get A grades, and therefore, they give difficult exams that many students fail; this is the weeding out process that every pre-health student is apprehensive about.

To succeed in this competitive environment entails not just studying harder or longer, it means re-organizing textbook content so that it is meaningful to the student. This is the first text of its kind to employ a reliable, research-based strategy that incorporates a decision-based visual tool to solve chemistry textbook problems, ones that can make or break a career.

A synthesis reaction or direct combination reaction is one of the most common types of chemical reaction. In this form, a synthesis reaction is easy to recognize because you have more reactants than products. Two or more reactants combine to make one larger compound. One way to think of synthesis reactions is that they are the reverse of a decomposition reaction. In the simplest synthesis reactions, two elements combine to form a binary compound a compound made of two elements.

The combination of iron and sulfur to form iron II sulfide is an example of a synthesis reaction :. Another example of a synthesis reaction is the formation of potassium chloride from potassium and chlorine gas :.

As in these reactions, it's common for a metal to react with a nonmetal. One typical nonmetal is oxygen, as in the everyday synthesis reaction of rust formation :. Direct combination reactions aren't always just simple elements reacting to form compounds: Another everyday synthesis reaction, for example, is the reaction that forms hydrogen sulfate, a component of acid rain. Here, the sulfur oxide compound reacts with water to form a single product:.

So far, the reactions you have seen have only one product molecule on the right-hand side of the chemical equation. Let's take a look at more complex reactions with multiple products. For example, the overall equation for photosynthesis:. Remember, the key to identifying a synthesis or direct combination reaction is to recognize two or more reactants form a more complex product molecule. Share Flipboard Email. Anne Marie Helmenstine, Ph. Chemistry Expert. Helmenstine holds a Ph. She has taught science courses at the high school, college, and graduate levels.

Facebook Facebook Twitter Twitter. Updated December 02, The glucose molecule is more complex than either carbon dioxide or water. Certain synthesis reactions form predictable products. For example:. Combining two pure elements will form a binary compound. A metallic oxide and carbon dioxide will form a carbonate.

Binary salts combined with oxygen form a chlorate. ThoughtCo uses cookies to provide you with a great user experience.

Complex Synthesis Reactions. Many synthesis reactions are far more complex than A + B → C. For example, organic synthesis reactions may involve more than two different molecules, and mixtures of products can occur along with unreacted starting materials. Intermediate molecules may form that can lead to the formation of byproducts.
