What is a molecular equation?
A molecular equation is an equation in which the formulas of the compounds are written as though all substances exist as molecules. However, there is a better way to show what is happening in this reaction. Other common categories of single-replacement reactions are hydrogen replacement and halogen replacement.
What does a molecular equation look like?
Molecular equations show species reacting as their molecular formula, with subscripts added to indicate their solid, liquid, gaseous, or aqueous nature. Subscripts are not needed to describe the state of the matter, because all ions are in aqueous solution.
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 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 molecular reaction?
1: Atoms bond to form molecules: Two or more atoms may bond with each other to form a molecule. When two hydrogens and an oxygen share electrons via covalent bonds, a water molecule is formed. Chemical reactions occur when two or more atoms bond together to form molecules or when bonded atoms are broken apart.
What is an ionic equation explain with an example?
Explain giving an example. An equation which shows only the atoms and ions that actually take part is called an ionic equation. Such ions which remain as such and do not take part in the reaction are not indicated. Write a balanced chemical equation with state symbols for the following reactions.
How do you write a balanced equation?
Balanced chemical equation: A chemical equation in which the number of each type of atom is equal on the two sides of the equation. Subscripts: Part of the chemical formulas of the reactants and products that indicate the number of atoms of the preceding element.
What are the steps to balancing equations?
Change the coefficients (the numbers in front of the compound or molecule) so that the number of atoms of the element is the same on each side of the equation. Remember, to balance an equation, you change the coefficients, not the subscripts in the formulas.
How do you balance an equation algebraically?
The strategy for balancing chemical equations algebraically is as follows:Write a different letter coefficient in front of each compound in the equation.Write algebraic expressions or rules for each element that equate its atoms on the LHS and RHS.
What is the advantage of writing net ionic equations?
The advantage of net ionic equations is that they show only those species that are directly involved in the reaction.
