Interpretation:
The physical states that correspond to the pictorial representation are to be stated.
Concept introduction:
A substance which has some mass and occupies space is termed as matter. It exists in three physical states that are solid, liquid and gas. The force of attraction between atoms determines the

Answer to Problem 1CE
The illustration A, B, C represents the solid state, liquid state and gaseous state respectively.
Explanation of Solution
The given figure is shown below.
Figure 1
Illustration A is a solid state as the force of attraction between atoms is very strong and the atoms are in a definite shape. On the other hand, illustration B is a liquid state as the atoms are far from each other because the force of attraction between atoms is less. The illustration C represents the gaseous state as atoms are very far from each other because the force of attraction between atoms is negligible.
Illustration A, B, C represents solid state, liquid state and gaseous state respectively.

- A certain inorganic cation has an electrophoretic mobility of 5.27 x 10-4 cm2s-1V-1. The same ion has a diffusion coefficient of 9.5 x 10-6cm2s-1. If this ion is separated from cations by CZE with a 75cm capillary, what is the expected plate count, N, at an applied voltage of 15.0kV? Under these separation conditions, the electroosmotic flow rate was 0.85mm s-1 toward the cathode. If the detector was 50.0cm from the injection end of the capillary, how long would it take in minutes for the analyte cation to reach the detector after the field was applied?arrow_forward2.arrow_forwardPlease solve for the following Electrochemistry that occursarrow_forward
- Commercial bleach contains either chlorine or oxygen as an active ingredient. A commercial oxygenated bleach is much safer to handle and less likely to ruin your clothes. It is possible to determine the amount of active ingredient in an oxygenated bleach product by performing a redox titration. The balance reaction for such a titration is: 6H+ +5H2O2 +2MnO4- à 5O2 + 2Mn2+ + 8H2O If you performed the following procedure: “First, dilute the Seventh Generation Non-Chlorine Bleach by pipetting 10 mL of bleach in a 100 mL volumetric flask and filling the flask to the mark with distilled water. Next, pipet 10 mL of the diluted bleach solution into a 250 mL Erlenmeyer flask and add 20 mL of 1.0 M H2SO4 to the flask. This solution should be titrated with 0.0100 M KMnO4 solution.” It took 18.47mL of the KMnO4 to reach the endpoint on average.
