Write the half-reactions that take place at the anode and at the cathode. Considering the nature of potential in this context, it is clear that the potential of a single half-cell or a single electrode cant be measured; transfer of electrons requires both a donor and recipient, in this case a reductant and an oxidant, respectively. What would you do to follow up with the interviewer after the interview? What is protectionism? Cross), Exam 2 Practice Questions KEY Fall 2017 Biol 101, Soil biodiversity Spring 2020 (1) (Auto Recovered), Exam 1 Study Guide - Lecture notes Ch. But 6.022 1023 is 1 mol, while 12.044 1023 is 2 mol (and the number is written that way to make this more obvious), so we can simplify this version of the equation by writing it as, \[\ce{2 \;mol\; H_2 + 1\; mol\; O_2 2 \;mol\; H_2O}\nonumber \], We can leave out the word mol and not write the 1 coefficient (as is our habit), so the final form of the equation, still balanced, is, Now we interpret the coefficients as referring to molar amounts, not individual molecules. The melting points of Cu, Ag and Au follow the order____________. Excellent!

Moles of Ag/ Ag+ = 0/ 0 =0, rounded to nearest integer = 1: Moles of Ag / moles of Cu = 0 moles/0 moles = 2, Balanced equation: 2AgNO 3 (aq) + Cu (s) Cu (NO 3 ) 2 (aq) + 2Ag (s). These coefficients also have the ratio 2:1:2 (check it and see), so this equation is balanced. I answered 1- a) thru c) this is the results from the lab I need 2. My hypothesis was that the mole relationship between silver and copper will be 2 mol Cu: 1 mol Ag ratio. a. internalize positive externalities If the inputs were swapped, the reported voltage would be +0.47 V. The entry for the putative oxidant, Fe2+, appears above the entry for the reductant, Cr, and so a spontaneous reaction is predicted per the quick approach described above. We use the ratio to find the number of moles of NaOH that will be used. mass (Ag = 107.84 g/mol)] (mol).
