Combustion of a fuel sample in a bomb calorimeter increases the temperature of the entire system by 5.10 °C if the calorimeter contains 1700 g of water, but only by 4.00 °C if the calorimeter contains 2200 g of water. What is the heat capacity of the dry bomb calorimeter assembly? Assume that the specific heat capacity of water is 4.18 J g–1 °C–1.
Polonium is a rare element with 33 radioisotopes. The most common one, P210o, has 84 protons and 126 neutrons. When P210o decays, it emits an alpha particle, which is a helium nucleus 2 protons and 2 neutrons. P210o decay is tricky to detect because alpha particles do not carry very much energy compared to other forms of radiation. For example, they can be stopped by a single sheet of paper or a few inches of air. That is one reason why authorities failed to discover toxic amounts of P210o in the body of former KGB agent Alexander Litvinenko until after he died suddenly and mysteriously in 2006. What element does an atom of P210o change into after it emits an alpha particle.
Polonium is a rare element with 33 radioisotopes. The most common one, 210Po, has 82 protons and 128 neutrons. When 210Po decays, it emits an alpha particle, which is a helium nucleus (2 protons and 2 neutrons). 210Po decay is tricky to detect because alpha particles do not carry very much energy compared to other forms of radiation. They can be stopped by, for example, a sheet of paper or a few inches of air. This property is one reason why authorities failed to discover toxic amounts of 210Po in the body of former KGB agent Alexander Litvinenko until after he died suddenly and mysteriously in 2006. What element does an atom of 210Po decay into after it emits an alpha particle?
Which of the following statements about the mass number of an atom is incorrect? a. It has a unit defined as a dalton. b. On Earth, it equals the atomic weight. c. Unlike the atomic weight of an atom, it does not change when gravitational forces change. d. It equals the number of electrons in an atom. e. It is the sum of the protons and neutrons in the atomic nucleus.
