Hii ndiyo swali lako la mwisho la bure leo! a) Jina la dutu A: Dutu A inatumika kukausha gesi ya hidrojeni kabla haijaitikia. Jina la dutu A ni: Anhydrous calcium chloride (Kloridi ya kalsiamu isiyo na maji). b) Eleza uchunguzi uliofanywa kwenye bomba la mwako: Copper (II) oxide ni nyeusi. Baada ya mmenyuko, rangi itabadilika. Uchunguzi ni: Rangi nyeusi ya copper (II) oxide inabadilika na kuwa kahawia-nyekundu. c) Eleza uchunguzi uliofanywa katika (b) hapo juu: Hidrojeni ni wakala wa kupunguza (reducing agent) na hupunguza copper (II) oxide kuwa shaba (copper) ya metali. Maelezo: Gesi ya hidrojeni hupunguza copper (II) oxide nyeusi kuwa shaba (copper) ya metali yenye rangi ya kahawia-nyekundu, huku ikitengeneza maji. Mlinganyo wa mmenyuko ni: H_2(g) + CuO_(s) heat Cu_(s) + H_2O_(g) Last free one today — make it count tomorrow, or type /upgrade for unlimited.
