Question

hcl is a strong electrolyte Classify each of the following elements as a molecular as a molecular solid, an ionic solid, a metallic solid, of a network covalent solid. Ge(melting point = 937 degree C, conducts electricity very poorly) Ga (melting point = 30 degree C, conducts electricity well) P(melting point = 280 degree C, does not conduct electricity at all) Each of the following substances is a solid at room temperature. What would you expect to be the most important type of attractive force between individual formula units in each of these substances? Base your answers on the chemical formulas and the positions of the elements in the periodic table: you should not need to look up any additional information. Chromium can combine with oxygen to form three different compounds, which described below: CrO: melting point > 1000 degree C, insoluble in water and in all organic solvents Cr_2O_3: melting point 2270 degree C, insoluble in water and in all organic solvents CrO_3: melting point 196 degree C, soluble in water and in several organic solvents Classify each of these compounds as a molecular solid, an ionic solid, a metallic solid, or a network covalent solid, and explain your answer. Which of the three types of intermolecular forces (London dispersion forces, dipole-dipole attraction, and hydrogen bonding) will play a significant role in determining the physical properties of each of the following substances? There may be more than one correct answer for a given compound. The following three compounds arc isomers (they have the same chemical formula) but they have quite different boiling points one boils at 82 degree C, one at 135 degree C. and one at 235 degree C. Match each substance with the correct boiling point, and explain your reasoning. *HCI is a strong electrolyte. Its melting point and boiling point are -114 degree C and -85 degree C, respectively. What state 9solid/liquid/gas) is HCI in at room temperature? A student concludes that HCI is an ionic compound, based on the fact that it ionizes completely in aqueous solution. Would you agree with this conclusion? If not, what sort of compound is HCI? Be sure to discuss the melting and boiling points in your answer.

Explanation / Answer

6.

Part A

HCl is in gas state at room temperature (25°C), because this temperature is greater than its boiling point.

Part B

No I don't agree, yes the HCl ionizes completely in aqueous solution but this is because HCl it's a strong acid.

Some the properties of ionic compounds are the following:

HCl doesnt have these properties, therefore is not a ionic compound.
