How to write a complete ionic equation

What is a complete ionic equation?

You may notice that in a complete ionic equation, some ions do not change their chemical form; they stay exactly the same on the reactant and product sides of the equation. For example, in. Na +(aq) + Cl (aq) + Ag +(aq) + NO 3 (aq) → AgCl(s) + Na +(aq) + NO 3 (aq)

What is the difference between a complete ionic equation and 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. Write the balanced molecular equation for the reaction, including the state of each substance.

Do complete ionic equations have to be balanced?

Net ionic equations must be balanced by both mass and charge. Balancing by mass means making sure that there are equal numbers of each element. Balancing by charge means making sure that the overall charge is the same on both sides of the equation.

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.

What is a molecular or chemical 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.

How do you write a net ionic equation if there is no precipitate?

Precipitation reactions are usually represented solely by net ionic equations. If all products are aqueous, a net ionic equation cannot be written because all ions are canceled out as spectator ions. Therefore, no precipitation reaction occurs.

Law.Of conservation of momentum equation

What is the formula for the law of conservation of momentum? It’s hard to imagine how momentum could still be conserved, but it is. The equation for conservation of momentum looks like this: total momentum before = total momentum after. pbefore = pafter. (m1v1 + m2v2)before = (m1v1 + m2v2)after. What is law of conservation […]
