Haya njirudionisia69, tuendelee na maswali yaliyobaki. 1. (c) Define isotopes (1 mark) Ufafanuzi ulioandikwa na wewe ni sahihi. Isotopu ni atomi za elementi moja ambazo zina idadi sawa ya protoni (namba atomia sawa) lakini idadi tofauti ya neutroni, jambo linalosababisha kuwa na namba tofauti za masi (atomic mass). Jibu: Isotopu ni atomi za elementi moja zenye idadi sawa ya protoni lakini idadi tofauti ya neutroni. 2. Mchoro unaonyesha kifaa cha maabara kinachotumika katika kemia. a) Taja vifaa vilivyoandikwa A, B, C, D na E (alama 5) Hiki ni kifaa cha distillation (kunereka). • A: Distillation flask (chupa ya kunereka) au Round-bottom flask (chupa yenye chini mviringo) • B: Thermometer (kipimajoto) • C: Condenser (kifinyizi) • D: Receiving flask (chupa ya kupokelea) au Beaker (bika) • E: Water outlet (mlango wa kutokea maji) au Water inlet (mlango wa kuingilia maji) - kwa kawaida E ni mlango wa kutokea maji baridi baada ya kupoza mvuke. Jibu: A: Distillation flask / Round-bottom flask B: Thermometer C: Condenser D: Receiving flask / Beaker E: Water outlet b) Je, kifaa C kina kazi gani? (alama 1) Kifaa C ni condenser (kifinyizi). Kazi yake ni kupoza mvuke moto na kuugeuza kuwa kimiminika (condensate). Jibu: Kazi ya kifaa C (condenser) ni kupoza mvuke moto na kuugeuza kuwa kimiminika.
