# Simple Displacement Reactions & Balancing Chemical Reactions

• mdsa12
In summary, a simple displacement reaction is a chemical reaction where one element replaces another in a compound, resulting in the formation of a new compound. To balance a chemical equation, the number of atoms on each side must be equal. The key components of a simple displacement reaction are the reactants, products, and conditions. It differs from a double displacement reaction in that it involves the replacement of elements in one compound rather than the exchange of elements between two compounds. Simple displacement reactions have many practical uses in everyday life, such as in the production of metals, extraction of salt, and biological processes like photosynthesis and respiration.

## Homework Statement

Complete the simple displacement reactions and balance any chemical reactions.

## Homework Equations

copper + silver nitrate → __________ + ____________

## The Attempt at a Solution

Since copper on the periodic table can be Cu2+ or Cu+, my solution was
copper + silver nitrate → copper (I) nitrate + silver

The answer says: copper (II) nitrate. I don't know why this works when NO3- has a 1- charge.

Cu2+ is the most common and most stable copper ion, especially in aqueous solutions. Charge on NO3- doesn't matter, as it is only a spectator.

## 1. What is a simple displacement reaction?

A simple displacement reaction is a type of chemical reaction in which an element or group of elements replaces another element in a compound, resulting in the formation of a new compound. This type of reaction is also known as a single replacement reaction.

## 2. How do you balance chemical equations?

To balance a chemical equation, you must ensure that the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side. This is done by adjusting the coefficients in front of each compound or element in the equation.

## 3. What are the key components of a simple displacement reaction?

The key components of a simple displacement reaction are the reactants (the substances that are reacting), the products (the substances that are formed), and the conditions under which the reaction occurs (such as temperature and pressure).

## 4. What is the difference between a simple displacement reaction and a double displacement reaction?

A simple displacement reaction involves the replacement of one element in a compound, while a double displacement reaction involves the exchange of elements between two compounds. In a double displacement reaction, the reactants and products are both compounds, whereas in a simple displacement reaction, one of the reactants is an element.

## 5. How are simple displacement reactions useful in everyday life?

Simple displacement reactions have many practical applications, including the production of metals from their ores, the extraction of salt from seawater, and the production of bleach and other cleaning agents. They are also important in biological processes such as photosynthesis and respiration.
