NACE CP1 - (2) questions well solved 2023Cathode More noble region where electrons are consumed. Reduction occurs at the cathode Anode Part of the metal that corrodes. Oxidation occurs at the anode Return Path Connects cathode and anode and allows passage of electrons generated at the anode to the cathode Electrolyte Medium that conducts ionic (rather than electronic) current Negative Electrode Zinc case which corresponds to the anode in a corrosion cell H...

TOF steps - CORRECT ANSWER-1) ionisation 2) acceleration 3) ion drift 4) detection 5) analysis Electron impact - CORRECT ANSWER-Sample vaporised and electron gun fires high energy electrons at it which knock off 1 electron from each particle, making them 1+ ions NB- can knock off more than one e or break molecular ion electrospray ionization - CORRECT ANSWER-Sample dissolved in volatile solvent then injected through needle to give fine mist which is attached to positive end of high v...

CHEM 120 Week 2 Discussion 1 - Chemical Names (graded) Sulfates, sulfites, nitrates, nitrites—how does one keep all of these similar but different names straight? Let’s begin this discussion by talking about the naming of different compounds. Why would it be important to make sure that you know which compound is associated with which name? To apply these concepts, look at problems 18 & 22 on page 122. Choose one part of the problem, & provide your answer. Check out the following ex...
