100 POINTS This isn't a serious question, but for one on my classes in high school I have to do a presentation in front the whole class, considering i've done many presentations in the past considering I took a class for it and each assignment we had was making a presentation on a certain topic and presenting it so i'm pretty used to it, but i'm really nervous about it and I have the option to have someone present it for me but i'm to nervous to do it, but i'm scared that no one will want to do it for me because i'm the quiet and shy girl, and I don't know anyone in that class, and I don't have friends anyway... but that's not the point, i've had a breakdown already and I was just crying for 30 minutes straight, and it's stressing me out I don't know what to do, any advice? Please don't be mean, i've already had a bad day. :(

Acetic acid  /əˈsiːtɪk/, systematically named  ethanoic acid  /ˌɛθəˈnoʊɪk/, is a colourless liquid  organic compound  with the  chemical formula  ch3cooh (also written as ch3co2h or c2h4o2). when undiluted, it is sometimes called  glacial acetic acid.  vinegar  is no less than 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water. acetic acid has a distinctive sour taste and pungent smell. in addition to household vinegar, it is mainly produced as a precursor to  polyvinyl acetate  and  cellulose acetate. it is classified as a  weak acid  since it only partially  dissociates  in solution, but concentrated acetic acid is corrosive and can attack the skin.acetic acidnamespreferred iupac nameacetic acidsystematic iupac nameethanoic acidother namesvinegar (when dilute); hydrogen acetate; methanecarboxylic acid[1][2]identifierscas number64-19-7  3d model (jsmol)interactive image3dmetb00009 reference506007chebichebi: 15366  chemblchembl539  chemspider171  drugbankdb03166  echa infocard100.000.528ec number200-580-7e numbere260  (preservatives)gmelin reference1380iuphar/bps1058keggd00010  meshacetic+acidpubchem  cid176rtecs numberaf1225000uniiq40q9n063p  un number2789inchiinchi=1s/c2h4o2/c1-2(3)4/h1h3,(h,3,4)  key:   qtbsbxvteameqo-uhfffaoysa-n  smilescc(o)=o
