Interpretation:
The formulas for the given compounds are to be stated. The characteristic of the polyatomic ions of the colored compounds that are not found in the white compounds is to be stated. The other polyatomic anions that would form colored compounds of potassium are to be predicted.
Concept introduction:
Ionic compounds are those compounds that have the strong electrostatic force of attraction between the oppositely charged ions. The positively charged ion is known as cation and negatively charged ion is called anion. Conventionally, the formula of the cation is written at left-hand side and formula of the anion is written at right-hand side while writing the formula of an ionic compound.

- Police officers confiscate a packet of white powder that they believe contains heroin. Purification by a forensic chemist yields a 39.69 mg sample for airproof combustion analysis. The sample gives 99.96 mg of CO2 and 21.34 mg of H20. A second sample is analyzed for nitrogen content, which is 3.8%. What is the empirical formula of the compound? List the elements in standard order for carbon compounds: C followed by H followed by other elements in increasing atomic number. Formula: 2 Edit The formula for heroin is C21H23NO5. Select the best response that characterizes these results: the white powder does not contain heroin because the formulas do not match. the white powder could contain heroin because the formulas match closely enough. no conclusions can be drawn because there is insufficient information. the white powder must contain heroin because the formulas match.

- • Sucrose: C12 H22O11 • Copper (I) Chloride: CuCl • lodine: I2 • Potassium lodide: KI Our goal is to try to find a pattern for which compounds conduct electricity when dissolved in water, and which don't. One hint is to look for patterns in which kinds of atoms form substances that conduct when dissolved, and which kinds of atoms form substances that don't conduct when dissolved.
