Neutralization cov tshuaj tiv thaiv yog generalally exothermic thiab yog li ΔH yog qhov tsis zoo. Kev ntsuas kub yog ua los ntawm kev ua cov tshuaj tiv thaiv hauv lub thawv tshwj xeeb hu ua calorimeter. Lub tshav kub (Q) muab tawm los ntawm cov tshuaj tiv thaiv neutralization yog absorbed los ntawm cov tshuaj tiv thaiv thiab cov calorimeter.
Vim li cas neutralization cov tshuaj tiv thaiv exothermic?
SIJ li cov kua qaub muaj zog thiab cov hauv paus muaj zog tau sib cais tag nrho hauv kev daws, tsis muaj cov ntawv cog lus raug raug tawg. Kev tsim ntawm ob qho kev sib cog lus muaj zog heev ntawm hydrogen thiab hydroxide ion yog lub luag haujlwm rau neutralization cov tshuaj tiv thaiv exothermictus cwj pwm.
Puas neutralization exothermic lossis endothermic?
Qee yam piv txwv ntawm exothermic cov tshuaj tiv thaiv yog: combustion (hluav taws) cov tshuaj tiv thaiv nruab nrab ntawm cov kua qaub thiab alkalis. Cov tshuaj tiv thaiv ntawm dej thiab calcium oxide.
Puas neutralization yog cov tshuaj tiv thaiv endothermic?
Thaum koj tso cov tshuaj tiv thaiv acid "alkaseltzer" rau hauv dej, qhov tshuaj tiv thaiv no tshwm sim. Nws kuj yog siv nyob rau hauv cov khoom confectionary los muab cov nyhuv "fizz". Ntseeg endothermic reactions zoo li qhov no tsis tshwm sim ntau. … Yog li, nyob rau hauv cov ntsiab lus, neutralization tshwm sim tsis yog ib txwm exothermic.
Puas yog nruab nrab ntawm cov kua qaub thiab lub hauv paus endothermic lossis exothermic?
Acid base neutralization cuam tshuam nrog kev tsim cov ntsev thiab dej. Cov txheej txheem zoo li noyog inevitably exothermic.
