Moles of carbon dioxide gas produced by the reaction. When the components of the reaction are mixed, a net amount of moles of carbon dioxide gas are generated. Some of the gas will remain disolved in the water while the rest will escape into the graduated cylinder (moles collected). Calculate the net amount of moles of carbon dioxide gas produced in the reaction (Hint: use stoichiometry.)

Which of the following statements is true? a. elements in the last period are radioactive. b. atomic weight is the same as atomic mass. c. elements in the same group have the same number of electron shells. d. atomic number equals the number of neutrons in the nucleus of an atom.

How many moles of gas are present if p=11 atm, v=12l, t=185k?

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
