What is a molecular equation
What does a molecular equation show?
Molecular equations show species reacting as their molecular formula, with subscripts added to indicate their solid, liquid, gaseous, or aqueous nature. Ionic equations show species reacting as their ionic components.
What is the difference between a molecular equation and a net ionic equation?
A molecular equation is valuable because it shows exactly what substances were used in a reaction. A complete ionic equation shows all the ions in a solution, while a net ionic equation shows only the ions that participate in a reaction to form products.
What is an ionic equation?
Similar to a molecular equation, which expresses compounds as molecules, an ionic equation is a chemical equation in which the electrolytes in aqueous solution are expressed as dissociated ions. The ions in aqueous solutions are stabilized by ion-dipole interactions with water molecules.
What is a molecular equation example?
Figure 1. The white silver chloride precipitate instantly forms when a solution of silver nitrate is added to a solution of sodium chloride. Image from Wikimedia. This is called a molecular equation.
Are molecular equations balanced?
A molecular equation is sometimes simply called a balanced equation. In a molecular equation, any ionic compounds or acids are represented as neutral compounds using their chemical formulas. The state of each substance is indicated in parentheses after the formula.
What is the molecular formula for c4h10?
Of butane the molecular formula is C4H10.
What is the difference between chemical and molecular formula?
The simplest types of chemical formulae are called empirical formulas, which use letters and numbers indicating the numerical proportions of atoms of each type. Molecular formulae indicate the simple numbers of each type of atom in a molecule, with no information on structure.
What are the empirical and molecular formula?
There are three main types of chemical formulas: empirical, molecular and structural. Empirical formulas show the simplest whole-number ratio of atoms in a compound, molecular formulas show the number of each type of atom in a molecule, and structural formulas show how the atoms in a molecule are bonded to each other.
How do you write a balanced ionic equation?
Writing A Balanced Ionic EquationExample:Solution:Step 1: Write the equation and balance it if necessary.Step 2: Split the ions. (Only compounds that are aqueous are split into ions.)Step 3: Cancel out spectator ions. Example:Solution:Step 1: Write the equation and balance it.
Are ionic and half equations the same?
These are known as half-equations. The two half-equations combined give the overall equation. Ionic half-equation simply refers to the fact that we simplify the half-equation by only showing the ions that undergo change.
What is an ionic equation give an example?
(i) Solutions of barium chloride and sodium sulphate in water react to give insoluble barium sulphate and the solution of sodium chloride. (ii) Sodium hydroxide solution (in water) reacts with hydrochloric acid solution (in water) to produce sodium chloride solution and water.
