Acertain 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 mm solution of m(no) and the right half cell with a 3.00 m 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 20.0 °c. o left right which electrode will be positive? 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.

Construct the hypothetical phase diagram for metals a and b between room temperature (20c) and 700c, given the following information: * the melting temperature of metal a is 480c. • the maximum solubility of b in a is 4 wt% b, which occurs at 420c. • the solubility of b in a at room temperature is 0 wt% b. • one eutectic occurs at 420c and 18 wt% b–82 wt% a. • a second eutectic occurs at 475c and 42 wt% b–58 wt% a. • the intermetallic compound ab exists at a composition of 30 wt% b–70 wt% a, and melts congruently at 525c.• the melting temperature of metal b is 600c. • the maximum solubility of a in b is 13 wt% a, which occurs at 475c. • the solubility of a in b at room temperature is 3 wt% a.
