What is a net equation?
The net ionic equation is the chemical equation that shows only those elements, compounds, and ions that are directly involved in the chemical reaction.
What chemicals are present in a net ionic equation?
A net ionic equation shows only the chemical species that are involved in a reaction, while a complete ionic equation also includes the spectator ions.
What is 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.
How do you write a balanced ionic equation?
Write the ionic equation by breaking all the soluble ionic compounds (those marked with an (aq)) into their respective ions. Each ion should be shown with its charge and an (aq) to show that it is present in solution. Use coefficients to show the number of each ion present.
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 is the meaning of ion?
an electrically charged atom or group of atoms formed by the loss or gain of one or more electrons, as a cation (positive ion ), which is created by electron loss and is attracted to the cathode in electrolysis, or as an anion (negative ion ), which is created by an electron gain and is attracted to the anode.
What is the net ionic equation of the reaction of zncl2 with NaOH?
Zn(CL)2 and NaOH reaction creates NaCl and Zn(OH)2. All compounds in reaction are soluble except Zn(OH)2. For the net ionic equation, we would have Zn + OH—>ZnO(H2); balanced on both sides.
What is molecular formula and example?
The molecular formula of a compound may be the empirical formula, or it may be a multiple of the empirical formula. For example, the molecular formula of butene, C4H8, shows that each freely existing molecule of butene contains four atoms of carbon and eight atoms of hydrogen. Its empirical formula is CH2.
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.
