Portage Learning Chem 210 - Module 2 Problem Set What is the shape of water? Bent. The bond angle is 104.5 degrees. What is autoionization, and how is it important for water? Autoionization is the ability of a compound to react with itself to form ions. One water molecule reacts with a second molecule to form two ions: H3O+ and OH-. These ions exist in small amounts in pure water and influence the chemistry of water. Name the three non-covalent forces ...

Why are alpha particles deflected by the nucleus? - Because both the alpha particles and the nucleus are positively charged and so the alpha particle is repelled. Is this statement (Dalton's Theory) true or false and why? "All atoms of an element are identical and have the same mass and properties." - False. Atoms of the same element can have different numbers of neutrons. What is the evidence that electrons are subatomic particles? - The nature of the electron is independent of the mat...
