How does dissolving an ionic compound in water increase electrical conductivity?

a. the water molecules electrostatically interact with the ions in the crystal and let the ions move freely.

b. the water molecules apply heat to break the ionic bonds in the crystal and let the ions move freely.

c. the water molecules chemically react with the ions in the crystal and let the ions move freely.

d. the water molecules remove heat to break the ionic bonds in the crystal and let the ions move freely.

Steam reforming of methane ( ch4) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which is the starting point for many important industrial chemical syntheses. an industrial chemist studying this reaction fills a 1.5 l flask with 3.5 atm of methane gas and 1.3 atm of water vapor at 43.0°c. he then raises the temperature, and when the mixture has come to equilibrium measures the partial pressure of carbon monoxide gas to be 1 .0 atm. calculate the pressure equilibrium constant for the steam reforming of methane at the final temperature of the mixture. round your answer to 2 significant digits.
