Electrochemical construction of Sdoped MnOx/Mn integrated
An integrated Sdoped MnO xbased electrode is fabricated with a novel twostep transformation approach The assynthesized Sdoped MnO xbased electrode exhibits excellent OER catalytic activity and longterm stability The critical role of S doping in stabilizing the Mn III O x active phase under OER conditions is discussed It opens a new avenue in rational design.
Cambridge IGCSE Chemistry (0620) Past and specimen paper
The first boiling tube contains cobalt chloride and the second contains limewater As the gas from the combustion reaches the first boiling tube any water present will condense on cooling and turn the cobalt chloride paper from blue to pink The second boiling tube will turn clear to cloudy indicating the presence of carbon dioxide.
