A student has a mixture of salt (NaCl) and sugar (C12H22O11). To determine the percent composition, the student measures out 5.84 g of the mixture and dissolves the sample in 100.0 mL of water. The student knows aqueous NaCl will react with aqueous silver nitrate (AgNO3) to form solid silver chloride (AgCl). The student determines the sugar will not react with silver nitrate. Write a balanced net ionic equation for the reaction of NaCl with AgNO3. How many mL of 1.0 M AgNO3 will be required to precipitate 5.84 g of AgCl

1. Net ionic equation:

2. Volume of 1.0M AgNO₃

Explanation:

1. Net ionic equation for the reaction of NaCl with AgNO₃.

i) Molecular equation:

It is important to show the phases:

ii) Dissociation reactions:

Determine the ions formed:

iii) Total ionic equation:

Substitute the aqueous compounds with the ions determined above:

iv) Net ionic equation

Remove the spectator ions:

2.  How many mL of 1.0 M AgNO₃ will be required to precipitate 5.84 g of AgCl

i) Determine the number of moles of AgNO₃

The reaction is 1 to 1: 1 mole of AgNO₃ produces 1 mol of AgCl

The number of moles of AgCl is determined using the molar mass:

ii) Determine the volume of AgNO₃

neutrons are in the middle of the atom and the electrons, which are much smaller.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
