This temperature is equal to 393K. 99. A gas mixture contains ammonia, hydrogen, and methane. The partial pressures of the gases are 2.0 atm, 1.75 atm, and 8.70 atm, respectively. The total pressure of the mixture is 12.45 atm. (use Dalton's law of Partial Pressures) 2.0 atm + 1.75 atm + 8.70 atm = 12.45 atm 100. An “empty” aerosol can at 110 K still contains gas at 1.40 atmosphere pressure. If an “empty” can is thrown into a 675 K fire, what is the final pressure in the heated can? P1= 1.40 atm T 1= 110 K (use formula P2 = P1 x T2 T 1) P2 = 1.40 atm x 675 K 110 K = 8.59 atm T2= 675 K 101. A gas has a volume of 6.50 L and a pressure of 90.0 kPa. The volume of the gas expands to 14 L. If the temperature remains constant, the new pressure of the gas will be 41.79 kPa. (use formula P2 = P1 x V1 V 2) P1 = 90.0 kPa V 1 69.50 L V 2 = 14 L P2 = 90.0 kPa x 6.50 L 14 L = 41.79 kPa 102. The splitting of a large nucleus into smaller ones is called fission reaction 103.All transuranium elements have a(n)_ atomic number greater than 92. 104..After one half-life _ one-half of an isotope will still remain. The other fraction will have decayed. 105. The portion of the electromagnetic spectrum with the shortest wavelength is Gamma rays 106.The nuclear reactor is the location where a fission reaction occurs inside a nuclear power plant 107. During a meltdown in a nuclear power plant, ionizing radiation can escape into the environment. 108. The portion of the electromagnetic spectrum with the longest wavelength is_ radio waves . 109. A CAT scan is a special type of electromagnetic radiation called X-rays 110. The distance from one wave peak to the next is called a wavelength . 111. The number of wave peaks that pass a given point in a set time is the frequency 112. Ionizing radiation that can pass through soft body tissue, but not bone is X-rays 113. Isotopes are considered _radioactive__ if their nucleus is unstable. 114. Isotopes can change from one element to another. This is called transmutation 115. High-energy electromagnetic waves possessing no electric charge are gamma rays 116. A helium nucleus consisting of two protons and two neutrons is an alpha particle 117. The joining of two small nuclei into a larger one is a fusion reaction 118. _ Electromagnetic radiation is also called radiant energy. 119.
