The chemical reaction between NaCl and ${\text{H}}{{\text{g}}_{\text{2}}}{\left( {{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{3}}}{{\text{O}}_{\text{2}}}} \right)_2}$ is as follows:

$\boxed{{\text{NaCl}}\left( {aq} \right) + {\text{H}}{{\text{g}}_{\text{2}}}{{\left( {{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{3}}}{{\text{O}}_{\text{2}}}} \right)}_2}\left( {aq} \right) \to {\text{H}}{{\text{g}}_{\text{2}}}{\text{C}}{{\text{l}}_2}\left( s \right) + 2{\text{Na}}{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{3}}}{{\text{O}}_2}\left( {aq} \right)}$

Further explanation:

The five types of chemical reactions are as follows:

1. Combination reactions:

These reactions are also known as a synthesis reaction. These are the reaction in which two or more reactants combine to form a single product. These are generally accompanied by the release of heat so they are exothermic reactions.

Example of combination reaction:

${\text{Ba}} + {{\text{F}}_2} \to {\text{Ba}}{{\text{F}}_2}$

2. Decomposition reactions:

The opposite of combination reactions is called a decomposition reaction. Here, a single reactant gets broken into two or more products. Such reactions are usually endothermic because energy is required to break the existing bonds between the reactant molecules.

Example of decomposition reaction:

$2{{\text{H}}_2}{{\text{O}}_2} \to 2{{\text{H}}_2}{\text{O}} + {{\text{O}}_2}$

3. Displacement reactions

Also known as replacement or metathesis reactions. Here, one of the reactants gets replaced by the other one. Generally, the more reactive element displaces the less reactive element. Both metals and non-metals can take part in displacement reactions.

Example of displacement reaction:

${\text{Cu}} + {\text{AgN}}{{\text{O}}_3} \to {\text{Ag}} + {\text{Cu}}{\left( {{\text{N}}{{\text{O}}_3}} \right)_2}$

4. Double displacement reactions

Double displacement reaction is defined as the reaction in which ions of two compounds interchange with each other to form the product. A general double displacement reaction between two compounds AX and BY can be written as follows:

${\text{AX}} + {\text{BY}} \to {\text{AY}} + {\text{BX}}$

Example of double displacement reaction:

${\text{N}}{{\text{a}}_2}{\text{S}} + {\text{HCl}} \to {\text{NaCl}} + {{\text{H}}_2}{\text{S}}$

5. Combustion reactions:

These are the reactions that take place when hydrocarbons are burnt in the presence of oxygen to form carbon dioxide and water. These are also referred to as burning.

Example of combustion reaction:

${\text{C}}{{\text{H}}_4} + {{\text{O}}_2} \to {\text{C}}{{\text{O}}_2} + {{\text{H}}_2}{\text{O}}$

NaCl reacts with ${\text{H}}{{\text{g}}_{\text{2}}}{\left( {{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{3}}}{{\text{O}}_{\text{2}}}} \right)_2}$ to form ${\text{H}}{{\text{g}}_{\text{2}}}{\text{C}}{{\text{l}}_2}$ and ${\text{Na}}{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{3}}}{{\text{O}}_2}$ . This is a double displacement reaction that occurs between NaCl and ${\text{H}}{{\text{g}}_{\text{2}}}{\left( {{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{3}}}{{\text{O}}_{\text{2}}}} \right)_2}$ . In this reaction, ${\text{C}}{{\text{l}}^-}$ is replaced by ${\left( {{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{3}}}{{\text{O}}_{\text{2}}}} \right)^-}$ and products are formed. ${\text{H}}{{\text{g}}_{\text{2}}}{\text{C}}{{\text{l}}_2}$ exists in the solid phase whereas ${\text{Na}}{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{3}}}{{\text{O}}_2}$ is present in aqueous phase.

For a family dinner, jose’s mom baked a loaf of bread. during the meal, his grandmother commented, “this bread is so dense! ” what do you think his grandmother meant by the word dense? you have some ideas regarding density already, but this experiment will enrich your understanding of the relationship between mass, volume and the density of objects. when making measurements in this experiment we will be using si units, the international system of units. the purpose of using si units is to have the ability to communicate and compare data results with other experiments without having to make conversions. measurement symbol si unit length m meter mass kg kilogram volume l liters density kg/l kilograms per liter any calculations that are performed during this experiment will ultimately be reported in scientific notation. recall that scientific notation is extremely important when we have data that is extremely small or large. scientists rely on a standard form of communication to quickly make hypotheses and judgements based on data. what is the density of block a? a0kg/l what is the density of block b? a1kg/l what is the density of block c? a2kg/l what is the density of block d? a3kg/l what is the density of block e? a4kg/l which block is the densest? a5
