Calculate the number of vacancies in gold per cubic centimeter at 1000 K, where the density and atomic weight for gold at are 18.63 g/cm3 and 196.9 g/mol, respectively, at 1000 K. The energy for vacancy formation in gold is 0.98 eV / atom. (Please express scientific notation using E to indicate the exponent - for example, 2.5E3

Need ! asap will mark 10 pts using the room temperature line (orange line) and your periodic table, make lists that identify the state of matter (gas, liquid, or solid) in which each element you plotted exists at room temperature. explain your answers

To find the enthalpy of a reaction in the lab, you measured the of the reactants and the change during the reaction.

The diagrams to the right show the distribution and arrangement of gas particles in two different containers. according to kinetic-molecular theory, which of the following statements is true? check all that apply. if the temperatures of both containers are equal, container a has greater pressure than container b. if the volume of container a decreased, its pressure would decrease. if the pressure in both containers is equal, container a has a lower temperature than container b.
