Concept explainers
Interpretation:
The substance that conducts electricity when dissolved in water 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
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. Strong electrolytes conduct the electricity.
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 first compound to be prepared in the laboratory was(a) Methane(b) Ethyl alcohol(c) acetic acid (d) Urea.arrow_forwardResearchers isolated an unknown substance, X, from rabbit muscle. They determined its structure from the following observations and experiments. (a) Qualitative analysis showed that X was composed entirely of C, H, and O. A weighed sample of X was completely oxidized, and the H2O and CO2 produced were measured. This quantitative analysis revealed that X contained 40.00% C, 6.71% H, and 53.29% O by weight. (b) The molecular mass of X, as determined by mass spectrometry, was 90.00 atomic mass units (u). (c) Infrared spectroscopy showed that X contained one double bond. (d) X dissolved readily in water, and the solution demonstrated optical activity when tested in a polarimeter. (e) The aqueous solution of X is acidic. What is the empirical formula of X?arrow_forward(a) If an automobile travels 225 mi with a gas mileage of 20.5mi/gal, how many kilograms of CO2 are produced?
