Writing and balancing chemical reactions worksheet answers

Balancing chemical equations Video transcript - Balancing chemical equations is one of those concepts in chemistry that often confuses people. But I think we'll see that if we work through this carefully and methodically, and we also appreciate the art of balancing chemical equations, that it's actually not too bad. So first of all, what is a chemical equation? Well this is a chemical equation right over here.

Writing and balancing chemical reactions worksheet answers

Chemical Reactions Having completed the prior unit on atomic structure and the naming of elements and compounds, the students are now ready to start looking at how atoms and molecules can rearrange themselves during chemical reactions.

The focus of this chapter is primarily on the basic mechanics of writing out and predicting the results of chemical reactions. Starting with the relatively simple synthesis and decomposition reactions, we work our way up through single replacement, double displacement, and combustion.

Students will need to copy of a periodic table and polyatomic ions reference lis t to be able to complete these worksheets. All of the basic parts of a chemical reaction are covered by this worksheet. Students will identify the reactants, products, subscripts, and coefficients.

Included is information on the state of matter notation that indicates whether each substance is a solid, liquid, gas, or aqueous solution. Chemical reaction, product, reactant, subscript, coefficient, state of matter notation, solid, liquid, gas, aqueous solution, diatomic elements.

Predicting the products and balancing chemical reactions is the main skillset that students need to have leaving this chapter.

I start teaching this with synthesis reactions, because they are one of the simplest and most straightforward forms of chemical reactions. This worksheet provides a few examples of how to predict products of synthesis reactions using oxidation states as well as showing students how to balance.

Chemical reactions, synthesis reactions, balancing equations, predicting products, oxidation state. This worksheet is a good followup to the synthesis reactions worksheet, because all of the same rules and ideas apply, simply in reverse.

I keep the problems in this assignment simple by either focusing on simple binary ionic compounds or giving students the names of the products in advance. Chemical reactions, decomposition reactions, balancing equations, predicting products, oxidation state.

Single-replacement reactions involve reacting a lone element usually a metal with a compound, resulting in the cations switching places. Students will learn to use the activity series for the first time as part of this worksheet, as they identify when reactions will and will not occur.

Students will need to copy of an activity series chart to be able to complete this assignment Essential concepts: Chemical reactions, single replacement reactions, balancing equations, predicting products, oxidation state.

Double-displacement reactions involve the switching of cations between two compounds. A simplified solubility table is included as part of this assignment. Chemical reactions, double-displacement reactions, balancing equations, predicting products, oxidation state, precipitate, solubility, aqueous solution.

Combustion reactions are the last type of chemical reaction covered, and for many students, one of the most difficult to balance. The products are always the same -- carbon dioxide and water vapor, but the coefficients for balancing these equations often become double-digits. Chemical reactions, combustion reactions, balancing equations, predicting products.

In this episode of Mythbusters, they debunk a Braniac video viewable on Youtube that demonstrates an explosion produced by dropping cesium into a bathtub of water that is powerful enough to actually crack the bathtub.

As they perform the experiment, the Mythbusters illustrate two types of chemical reactions. First, dropping an alkali metal in water results in a single-replacement reaction, releasing hydrogen gas. The hydrogen gas then reacts with oxygen in a synthesis reaction, forming water and releasing a lot of energy in the form of heat and light.

This is also a good video to introduce the idea of the periodic law -- the alkali metals will react more violently with water as you move further down the group.

Chemical reactions, single-replacement reactions, synthesis reactions, alkali metals, periodic law. This segment of Mythbusters focuses on combustion. Specificially, is using a cell phone enough to initiate the combustion of gasoline, resulting in a fire or explosion at a gas station?

The answer is no, as there is a level of activation energy needed to initate combustion that simply is not present in the electromagnetic emissions of a cell phone. The Mythbusters do learn that the most common cause of gas station fires is static electricity discharge from people exiting their car.

Such a representation is known as chemical equation. A chemical equation is the representation of the chemical reactions. The LHS consists of the reactants and the RHS consists of the products. Balancing chemical equation is the process of equalising the number of each element in the reactants to the products.
