What number of protons and neutrons is contained in the nucleus of each of the following atoms? Assuming each atom is uncharged, what number of electrons is present? a. \(\frac{235}{92} \mathrm{U}\) b. \(_{13}^{2} \mathrm{Al}\) c. \(\frac{57}{26} \mathrm{Fe}\) d. \(\frac{208}{82} \mathrm{Pb}\) e. \(\frac{86}{32} \mathrm{Rb}\) f. \(\frac{41}{20} \mathrm{Ca}\)
The three most stable oxides of carbon are carbon monoxide (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.
In Section 1-1 of the text, the concept of a chemical reaction was introduced with the example of the decomposition of water, represented as follows: Use ideas from Dalton's atomic theory to explain how the above representation illustrates the law of conservation of mass.
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 liters of carbon dioxide for every 9 liters 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?
