Molecular equation

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.

What is the difference between a molecular equation and a complete ionic equation?

In comparison, the complete ionic equation tells us about all of the ions present in solution during the reaction, and the molecular equation tells us about the ionic compounds that were used as the sources of Ag+start text, A, g, end text, start superscript, plus, end superscript and Cl−start text, C, l, end text,

What is a 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.

What is the definition of molecular formula?

a chemical formula that indicates the kinds of atoms and the number of each kind in a molecule of a compound.

How do you find the molecular formula?

Divide the gram molecular mass by the empirical formula mass. Multiply each of the subscripts within the empirical formula by the number calculated in Step 2. Multiplying the subscripts within the empirical formula by this number gives you the molecular formula H2O2.

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.

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.

Do you simplify net ionic equations?

All you have to do is cancel out the “spectator ions”, which are ions that appear on both sides of the equation. What remains is the net ionic equation. Be sure to check that the coefficients are reduced to the lowest ratio. Note that this is different from the reaction described at the top of the page.

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.

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.

Depreciation equation

What are the 3 depreciation methods? There are three methods for depreciation: straight line, declining balance, sum-of-the-years’ digits, and units of production. What do you mean by depreciation? Definition: The monetary value of an asset decreases over time due to use, wear and tear or obsolescence. This decrease is measured as depreciation. How do you […]
