Does the lewis dot structure for Aluminum Oxide (Al2O3) look like this:OAl-O-AlO? If not, then how does it look?Also, could you help me make a lewis dot structure for Carbon Dioxide, Calcium Oxide, Diphosphorous Pentoxide, and Diiodine PentoxideI don't get this at all reallyI don't know how to tell whether or not it's ionic or convalentThanks for your help.
The electron dot structure of the Al is just Al3+This is because its three valence electrons are goneThe structure of the O is O(2-) with on three sides and oo on the fourth sideThe 's are O electrons and the o's are electrons gained from AlPut down 2 such Al's for every 3 O'sCalcium oxide: The same as for aluminum oxide, except Ca is 2+ and there is one Ca2+ for every OCarbon dioxide: Draw O C O and leave a space between eachDraw on the top and bottom of each O and between each O and CDraw oo between C and each O's are O valence electrons; o's are C valence electronsPhosphorus pentoxide: Draw O.O .P.O.P O.O Put o between the center O and each PPut oo between each P and each of the four other O'sPut on the top and bottom of the center O and the remaining three sides of the other four O'sNotice that P provides both electrons to the pairs that are shared between it and the outer four O'sThese are coordinate covalent bondsIodine pentoxide: The same as for P2O5Just remember that you have to have an extra oo on one side of each iodine, because they have 7 valence electrons.
If you have a seperate room keep small useful exercise equipment Use those equipment while reading and listening songs
drink 8 cups of water a day
I've lost 5 kilos in my first weekIt's my 10th day and I have included salad with some protein (egegg/ lean chicken) as you suggestedAfter 4 years of trying, the fat is finally coming offIt truly feels like magic! Get started today!
It's a pretty stupid idea, but I would say no more than 3 pounds of water weightOnce you drink a few glasses of water, the weight you sweated off will go right back on.
