The given substance K 2 Cr 2 O 7 is a strong electrolyte, weak electrolyte, or nonelectrolyte has to be identified. Concept introduction: Electrolytes: Ionic compounds dissociate in to two different ions like cation and anion, therefore its conduct the electricity. Ionic compounds are electrolytes, because it conducts an electric current when dissolved in water. Strong electrolyte: A compound that completely dissociates into its ions in aqueous solution. Strong acids and strong base are strong electrolyte because, they ionize completely. Weak electrolyte: A compound that dissociates partially in an aqueous solution. Aqueous solutions of weak electrolytes conduct less electricity. Weak acids and weak base are weak electrolyte because, they do not ionizing completely. Nonelectrolyte: Nonelectrolytes are not ionizing compound molecular compound. They do not conduct the electricity.

The given substance K2Cr2O7 is a strong electrolyte, weak electrolyte, or nonelectrolyte has to be identified.
Concept introduction:
Electrolytes:
Ionic compounds dissociate in to two different ions like cation and anion, therefore its conduct the electricity. Ionic compounds are electrolytes, because it conducts an electric current when dissolved in water.
Strong electrolyte:
A compound that completely dissociates into its ions in aqueous solution. Strong acids and strong base are strong electrolyte because, they ionize completely.
Weak electrolyte:
A compound that dissociates partially in an aqueous solution. Aqueous solutions of weak electrolytes conduct less electricity. Weak acids and weak base are weak electrolyte because, they do not ionizing completely.
Nonelectrolyte:
Nonelectrolytes are not ionizing compound molecular compound. They do not conduct the electricity.

6. Chlorine dioxide (CIO) is used as a disinfectant in municipal water-treatment plants. It decomposes in
a first-order reaction with a rate constant of 14 s. How long would it take for an initial concentration of
0.06 M to decrease to 0.02 M? [6 pts]
If possible, replace an H atom on the
a carbon of the molecule in the
drawing area with a methyl group
substituent, and replace an H atom
on the ẞ carbon with a hydroxyl
group substituent.
If one of the substituents can't be
added for any reason, just don't add
it. If neither substituent can be
added, check the box under the
drawing area.
