The balanced molecular, total ionic, and net ionic equations for the acid-base reaction between limestone and hydrochloric acid are to be written. Concept introduction: Strong acids and strong bases are the substance that dissociates completely into its ions when dissolved in the solution. They dissociate completely in water to release H + ions and OH − ions. Weak acids and weak bases are the substance that does not dissociate completely into its ions when dissolved in the solution. They dissociate partially in water to release H + ions and OH − ions. The driving force of the acid-base reaction is the formation of a gaseous product or precipitate in the reaction. There are three types of equations that are utilized to represent an ionic reaction: 1. Molecular equation 2. Total ionic equation 3. Net ionic equation The molecular equation represents the reactants and products of the ionic reaction in undissociated form. In total ionic reaction, all the dissociated ions that are present in the reaction mixture are represented and in net ionic reaction, the useful ions that participate in the reaction are represented. Spectator ions are the ions that are not a part of the actual chemical change but are present in the reaction mixture to balance the charge on both sides of the reaction. They are represented in the total ionic reaction. These are the dissolved ions present in the reaction mixture.

Interpretation Introduction

Interpretation:

The balanced molecular, total ionic, and net ionic equations for the acid-base reaction between limestone and hydrochloric acid are to be written.

Concept introduction:

Strong acids and strong bases are the substance that dissociates completely into its ions when dissolved in the solution. They dissociate completely in water to release H+ ions and OH− ions.

Weak acids and weak bases are the substance that does not dissociate completely into its ions when dissolved in the solution. They dissociate partially in water to release H+ ions and OH− ions.

The driving force of the acid-base reaction is the formation of a gaseous product or precipitate in the reaction.

There are three types of equations that are utilized to represent an ionic reaction:

1. Molecular equation

2. Total ionic equation

3. Net ionic equation

The molecular equation represents the reactants and products of the ionic reaction in undissociated form. In total ionic reaction, all the dissociated ions that are present in the reaction mixture are represented and in net ionic reaction, the useful ions that participate in the reaction are represented.

Spectator ions are the ions that are not a part of the actual chemical change but are present in the reaction mixture to balance the charge on both sides of the reaction. They are represented in the total ionic reaction. These are the dissolved ions present in the reaction mixture.

The emission data in cps displayed in Table 1 is reported to two decimal places by the chemist. However, the instrument output is shown in Table 2. Table 2. Iron emission from ICP-AES Sample Blank Standard Emission, cps 579.503252562 9308340.13122 Unknown Sample 343.232365741 Did the chemist make the correct choice in how they choose to display the data up in Table 1? Choose the best explanation from the choices below. No. Since the instrument calculates 12 digits for all values, they should all be kept and not truncated. Doing so would eliminate significant information. No. Since the instrument calculates 5 decimal places for the standard, all of the values should be limited to the same number. The other decimal places are not significant for the blank and unknown sample. Yes. The way Saman made the standards was limited by the 250-mL volumetric flask. This glassware can report values to 2 decimal places, and this establishes our number of significant figures. Yes. Instrumental data…
