Voltmeter A E C В D

In an electrolytic (non-spontaneous) cell, reduction occurs at the (A) Anode (B) Cathode

Which statement is true regarding the galvanic cell in which an electric current is being produced? Zn²* + 2e¯→Zn E° = -0.76 V Cu2* + 2e¯→Cu E° = +0.34 V V Salt Bridge Zn - Cu ZnSO«(aq) CUSO:(aq) (A) Oxidation occurs at the copper electrode. (B) The mass of the copper electrode is increasing. (C) Zinc ions are produced at the copper electrode. (D) Copper ions are produced at the copper electrode.

The answer is supposed to be in grams

A certaln metal M forms a soluble nitrate salt M(NO,). Suppose the left half cell of a galvanic cell apparatus is filled with a 3.00 M solution of M(NO,). and the right half cell with a 3.00 mM solution of the same substance. Electrodes made of M are dipped into both solutions and a voltmeter is connected between them. The temperature of the apparatus is held constant at 25.0 °C. O left do Which electrode will be positive? x10 O right Ar What voltage will the voltmeter show? Assume its positive lead is connected to the positive electrode. Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits. Explanation Check 2021 McGraw-Hill Education. Ali Rights Reserved.
