Concept explainers
(a)
Interpretation:
The net ionic equation for the reaction of NH4NO3 with NaOH should be written.
Concept introduction:
Acid -Base reaction:
The reaction between acid and base to produce a salt is called acid-base reaction.
Net ionic equation:
The only species which are contributes in the reaction are written in form of ions in reaction is called net ionic equation.
Molarity:
The concentration of the solutions is given by the term molarity and it is given by ratio between numbers of moles of solute present in litter of solution.
Molarity = No.molevolume (L)
Mole:
The mole of compound is given by the ratio between taken mass of the compound and molar mass of the compound.
Mole = Mass of the compoundMolar mass of the compound
Mole:
The mole of the solute is calculated by multiplication of concentration of solution and volume of the solution and it is,
Mole = Concentration (M)× volume (L)
(b)
Interpretation:
The percent purity of NH4NO3 in given sample should be calculated.

The chemical equation for the net ionic reaction of NaCl and KCl with silver nitrate, AgNO3, is shown below. Ag+(aq) + Cl(aq) → AgCl(s) The total mass of the NaCl/KCl mixture is 1.299 g. Adding 50.42 mL of 0.381 M solution precipitates out all of the Cl-. What are the masses of NaCl and KCl in the mixture? Atomic masses: g: Mass of NaCl g: Mass of KCL Ag = 107.868 g mol- 1 Cl = 35.453 g mol- 1 K = 39.098 g mol- N = 14.007 g mol−1 Na = 22.99 g mol−1 0 = 15.999 g mol 1 Question Help: ✓ Message instructor Submit Questionarrow_forwardPart 1.

- Identify the missing starting materials/ reagents/ products in the following reactions. Show the stereochemistry clearly in the structures, if any. If there is a major product, draw the structures of the major product with stereochemistry clearly indicated where applicable. Show only the diastereomers (you do not have to draw the pairs of enantiomers). If you believe that multiple products are formed in approximately equal amounts (hence neither is the major product), draw the structures of the products, and show the detailed mechanism of these reactions to justify the formation of the multiple products. If you believe no product is formed, explain why briefly. (6 mark for each, except f and g, which are 10 mark each)arrow_forward3.
