The Lewis Structure of ClF3 is pictured below.  What is the electron domain geometry (EDG) and molecular geometry (MG) of this molecule?

What is the C-C-C bond angle (

What is the electron domain geometry (EDG) and molecular geometry (MG) of CO32-?

Which of these statements best explains why the atomic radius of main group elements generally increases down a group in the Periodic Table?

The element oxygen exists in different forms in nature, including molecular oxygen (O2) and Ozone (O3). These two forms of oxygen are examples of                                .

The calculated value of (Z-S) is the same down a group, which means that Zeff should not change from top to bottom on the Periodic Table. However, a slight increase is observed.  Which statement below explains why?

If the temperature of a gas sample is quadrupled, and the size of the container that holds it is tripled, by what factor does the initial pressure change?

When calcium carbonate is heated, CO2 (g) is produced according to the following balanced equation: CaCO3 (s) → CaO + CO2 (g) If 5.00 g of CaCO3 (s) is heated, what volume (in L) of CO2 (g) would be produced when collected at a temperature of 27.0 ºC and a pressure of 0.920 atm?

The molar mass of CO2 is 44 g/mol while that of H2O is 18 g/mol.  Given that CO2 has a greater molar mass than H2O, why is CO2 a gas at room temperature and standard pressure while H2O is a liquid?

In 1910, Ernest Rutherford conducted his famous experiment in which he directed a beam of particles at a thin piece of gold foil, discovering a small, dense nucleus. What particles did he shoot at the gold foil in this experiment?
