DJ MUman Posted October 10, 2007 Report Share Posted October 10, 2007 Tā kā postā par skolu (uj, sen bija) daudzi rakstīja, ka ķīmija nav nekas grūts, tad domāju, ka šis arī nebūs nekas grūts: CH4 -> C2H6 -> C4H10 -> C2H4 -> C2H6 -> C2H5Cl -> C2H4 -> (-CH2-CH2-)n CH4 + Cl2 -> CH3Cl + HCl CH3Cl + CH3Cl + 2Na -> C2H6 + 2NaCl Trūkst 3 posmu ar C2H6 -> C4H10, C4H10 -> C2H4 un C2H4 -> C2H6 C2H6 + Cl2 -> C2H5Cl + HCl C2H5Cl -> C2H4 + HCl nC2H4 + C2H4 + ? -> (uz svītras polimerizācija) (-CH2-CH2-)n Tātad - lūgums uzrakstīt šos 3 posmus.

C2H6 + C2H4 has an activation energy (Ea) of 350 kJ/mol tatad C2H6 + C2H4 -> C4H10 + 350kJ Edited October 11, 2007 by 0xDEAD BEEF Link to comment Share on other sites More sharing options...
DJ MUman Posted October 11, 2007 Author Report Share Posted October 11, 2007 Njā šodien bija kontris ķīmijā, bet labi, ka par šo pārvērtību virkni stipri daudz punktu netika dots Cerams, ka kopumā būs laba atzīme Paldies Bīfijam par centību, bet šķiet, ka nav tas, jo mums nebija nekādu reakciju ar siltuma izdalīšanos. Droši vien, ka var slēgt ciet. Link to comment Share on other sites More sharing options...
