## What are the rules to balance the net ionic equations?

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.

## How do you balance ions?

Steps To Balance Ionic EquationsWrite the net ionic equation for the unbalanced reaction. Separate the net ionic equation into the two half-reactions. For one of the half-reactions, balance the atoms except for O and H. Repeat this with the other half-reaction.Add H2O to balance the O atoms. Balance charge.

## 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.

## 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.

## What is a balanced ionic equation?

A balanced ionic equation shows the reacting ions in a chemical reaction. These equations can be used to represent what happens in precipitation reactions .

## Do charges matter when balancing equations?

The charges of the ions in a chemical formula always add up to zero. This is because positive and negative charges attract each other. This continues to happen until the charges balance and there is no more attraction.

## 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 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.

## How do you write spectator ions?

Spectator ions may be either cations (positively-charged ions) or anions (negatively-charged ions). The ion is unchanged on both sides of a chemical equation and does not affect equilibrium. When writing a net ionic equation, spectator ions found in the original equation are ignored.

#### 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 […]
