Get started for freeThe three most stable oxides of carbon are carbon monoxide \((\mathrm{CO}),\) carbon dioxide \(\left(\mathrm{CO}_{2}\right),\) and carbon suboxide \(\left(\mathrm{C}_{3} \mathrm{O}_{2}\right) .\) The molecules can be represented as... Explain how these molecules illustrate the law of multiple proportions.
A sample of chloroform is found to contain 12.0 g of carbon, 106.4 g of chlorine, and 1.01 g of hydrogen. If a second sample of chloroform is found to contain 30.0 g of carbon, what is the total mass of chloroform in the second sample?
A combustion reaction involves the reaction of a substance with oxygen gas. The complete combustion of any hydrocarbon (binary compound of carbon and hydrogen) produces carbon dioxide and water as the only products. Octane is a hydrocarbon that is found in gasoline. Complete combustion of octane produces 8 L of carbon dioxide for every 9 L of water vapor (both measured at the same temperature and pressure). What is the ratio of carbon atoms to hydrogen atoms in a molecule of octane?
a. List the noble gas elements. Which of the noble gases has only radioactive isotopes? (This situation is indicated on most periodic tables by parentheses around the mass of the element. See inside front cover.) b. Which lanthanide element has only radioactive isotopes?
Radiotracers are radioactive substances that can be introduced into organisms by way of ingestion or injection and whose pathway can be traced by monitoring their radioactivity. How many protons and neutrons do the following radiotracers contain? a. Iodine-131, used in the diagnosis and treatment of illnesses of the thyroid gland. b. Thallium-201, used to assess the damage to the heart muscle in a person who has suffered a heart attack.
