Please answer all the questions. And please i need short answers, thanks. 01 2BUILDING UNDERSTANDINGS11. How many protons and electrons does oxygen have? What about hydrogen? (Draw amodel of each atom if that helps you think about the differences between them.)12. What have we figured out about attractions between oppositely charged particles?13. If we put these ideas together, how can we explain the partial negative charge on oxygenand the partial positive charge on hydrogen?14. How do partial charges affect attractions between water molecules? Draw several watermolecules, and use dotted lines to draw where one molecule is attracted to anothermolecule. (You can either insert a Google Doc Drawing or you can draw it on either paper oryour whiteboard, take a picture, and then insert into the blue box below.)Insert Drawing Here15. How does this help us explain why water molecules stek together?BACK TO THE SIMULATION (Check out mineral oil, again in "opaque" surface view.)16. Is mineral oil a symmetrical molecule? Does it have partial charges?17. Think back to lesson 3 and when we put drops of liquids on pennies. Could we get manydrops of oil to stick on a penny? What can we infer about attractions between mineral oilmolecules? Do we think it is a polar molecule?
