I2 + Cl2 (+2Cl2) > 2ICl3 {1} 2?Hf(ICl3)I2 + Cl2 (+2Cl2) > 2ICl + 2Cl2 {2} +14 kJmol^-12ICl +2Cl2 > 2ICl3 {3} 2(-88) kJmol^-1It’s difficult to show the tauanglilrr diagram here, so just try to visualize the triangle. Ignored the state symbols to avoid getting messy. Won’t be doing that in the real exams though.In my working, I’d put eqn {1} on top, and {2} and {3} in the left and right bottom corners of the diagram respectively.You can see that the (+2Cl2) in {1}will sort of balance eachother out, so there’s no need to consider bond energy of Cl2.By Hess’ Law, 2?Hf(ICl3)= 14+2(-88)= -162 kJmol^-1 ? ?Hf(ICl3)= -81 kJmol^-1So I guess the girl would have been correct, answer B.Let me know if you spot any errors, thanks.
If you are concerned about budget, you may want to stay in a backpackers hostels. You can get a bed in a dorm for as low as $18 or a room for about $35. Do a search for backpackers hostel singapore and you should find some. Stay about 3-4 days, eat at the hawker centres (singaporeans love food, so this is something you should experience) go to the prime shopping areas (Orchard Road, Vivo City), our beaches (East Coast Park and Sentosa), visit the Merlion and Empress Place where the statue of Sir Stamford Raffles is, visit Chinatown (the Chinese New Year decorations should still be there), visit Little India (24 hour shopping at Mustafa Centre where you can buy almost anything)You can move about using the public transport. It is very efficient. You can choose to buy a tourist pass for $8 a day for unlimited rides.Enjoy your trip!
singapore is definitely a fine city in all ways.its clean. its safe.(the security here sure is tight.)no air pollution.a developed country.good transport system.old and modern infrastructure.good museums.short time travelling from one place to another.good service.cosmopolitan.many different races and cultures.GOOD FOOD. you must try the food here! the varities due to multi races will blow you away… the must trys are hianese chicken rice(SUPER NICE!!!!)(chinese), roti prata(indian) the prata here is very different from the others and satay(malay) something like karbab but slighty different. and last but not least the definitely must try…. PANDAN CAKE. its a sponge cake that is light and is addded with pandan to create that distinct flavour. most tourists and celebrities from all over the world has totally fall in love with this local delicacy. try it and you’ll know. trust me. you will definitely regret if you dont’t. its so good.in all, hope you have fun in singapore. do check out the malls here too. hope you could bring back some good hunts. all the best!katee, singapore.
Thanks, but no luck
