- Some questions frequently asked by houseowners : chemistry chemical bonds?
♥ okay so i asked this question before and people were yelling at me for asking for answers (which is not what i was doing). i just need someone to explain the steps because im really bad at chemistry, and i really don't understand it :/ thanks how do i do this worksheet? its asking for the number of valence electrons and the type of bond of the following: o+o na+br s+o ca+i al+n h+h p+o rb+f h+cl i+brchemistry worksheet with answers practice?
♥ does anyone have any practice worksheets for: determining moles of ions in aqueous ionic solutions predicting whether a precipitation reactions occurs; writing ionic equations determining the molarity of h+ ions in an aqueous solution of an acid writing ionic equations for acid-base reactions finding the concentration of acid from an acid base titration determining the oxidation number of an element recognizing oxidizing and reducing agents identifying the type of redox reaction anything with net ionic/ molecular/total ionic/spectator ion naming it would help me a ton and get me practicing because i'm struggling with chem! thanks!chemical bonds ?
♥ how do i do this worksheet? its asking for the number of valence electrons and the type of bond of the following: o+o na+br s+o ca+i al+n h+h p+o rb+f h+cl i+brhelp with covalent bonding (pbr3)?
♥ i'm not sure how to do any of this worksheet my chemistry teacher gave us because she's a sub and not too good of a teacher. so if you could help me out with pbr3 i could probably figure the rest out i need the # of bonded atoms, the # of unshared pairs, the shape, the bond angle, and the hybridization? i can do lewis structures but i can't do any of the things she's asking. thanks!who can help me with my organic chemistry practice worksheet?
♥ can someone please help me with d) and 2)? they are both supposed to have two answers and i only have one answer for each. i'm just not sure what the other answer is. below is the link to my worksheet. http://tinypic.com/r/pye54/.
