A certain metal M forms a soluble nitrate salt M (NO3)₂. Suppose the left half cell of a galvanic cell apparatus is filled with a 5.00 M 2 solution of M (NO3), and the right half cell with a 50.0 mM solution of the same substance. Electrodes made of M are dipped into 2 both solutions and a voltmeter is connected between them. The temperature of the apparatus is held constant at 35.0 °C. 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. 0 left right x10 X

In each , decide whether the property measured was a chemical or physical property of X, if you can. If you don't have enough information to decide, choose can't decide in the third column. property R V H experiment Into one chamber of an electrochemical cell, a solution of X is introduced, along with a metal electrode. In the other chamber a solution of a known oxidizing reagent O is introduced, along with another metal electrode. The voltage across the electrodes is proportional to the tendency of O to react with X. By measuring this voltage, the value of R may be calculated. A sample of X is melted and put into a reservoir from which a very thin tube leads down. The rate at which X flows out of the tube is measured, and from this rate the value of V may be calculated. A sample of X is carefully weighed and put inside a sealed calorimeter. The calorimeter is heated electrically, and the amount of heat added determined by monitoring the electrical current used. The temperature of X is…
