The atomic number of beryllium (be) is 4, and the atomic number of barium (ba) is 56. which comparison is best supported by this information?
a: they are in the same group because they have similar atomic masses, but they are in different periods because they have different chemical properties.
b: they are in the same group because they have similar chemical properties, but they are in different periods because they have very different atomic numbers.
c: they are in the same group because their atomic numbers are each multiples of four, but they are in different periods because they have different chemical properties.
d: they are in the same group because they have similar atomic masses, but they are in different periods because they have very different atomic numbers.

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?
