Cov tshuaj tiv thaiv ntawm calcium oxide (CaO) thiab dej (H2O) tsim calcium hydroxide Ca(OH)2 yog ib qho exothermic ua ke tshuaj tiv thaiv. Cov tshuaj tiv thaiv no ua rau muaj cua sov ntau nrog rau lub suab nrov thiab yog li tau hais tias yog exothermic.
Hauv qhov no, hom tshuaj tiv thaiv dab tsi yog Ca Oh 2?
Kev tsim ntawm slaked txiv qaub (calcium hydroxide, Ca (OH))2) thaum dej ntxiv rau txiv qaub (CaO) yog exothermic.
Kuj Paub, puas yog CaO h2o cov tshuaj tiv thaiv redox? Teb: Yog, nws yog a tshuaj tiv thaiv redox.
Hauv qhov no, cov tshuaj tiv thaiv dab tsi yog calcium thiab dej?
Cov tshuaj calcium nrog dej Calcium reacts maj mam nrog dej. Qhov no yog nyob rau hauv sib piv nrog magnesium , tam sim ntawd saum calcium nyob rau hauv lub sij hawm lub rooj, uas yog zoo unreactive nrog dej txias. Cov tshuaj tiv thaiv tsim calcium hydroxide, Ca (OH)2 thiab hydrogen gas (H2).
Qhov sib npaug ntawm CaO h2o Ca OH 2 h2 yog dab tsi?
Chemical Equation Balancer Ca + H2O = Ca ( OH ) 2 + H2.
