Defining the Modern Periodic Table
What is the major difference between the periodic table created by Dmitri Mendeleev and the one created by Henry
Moseley?
O Moseley arranged the elements in order of increasing atomic mass.
O Moseley ignored variations resulting from isotopes.
O Moseley arranged the elements in order of increasing atomic number.
O Moseley divided the elements into four categories.

Waves that cause the most damage during an earthquake are a. surface waves c. s waves b. p waves d. ocean waves

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?
