Acell consists of a gold wire and a saturated calomel electrode (s. c.e.) in a 0.130 m auno 3 solution at 25 °c. the gold wire is connected to the positive end of a potentiometer, and the s. c.e. is connected to the negative end of the potentiometer. what is the half‑reaction that occurs at the au electrode? include physical states.

Ahypothrticalax type of ceramic material is known to have a density of 2.10 g/cm3 and a unit cell of cubic symmetry with a cell edge length of 0.57 nm. the atomic weights of the a and x elements are 28.5and 30.0 g/mol, respectively. on the basis of this information, which of the following crystal structures is (are) possible for this material: sodium chloride, cesium chloride, or zinc blende

How can you use chemical equations to predict the products of the reaction you can carry out?

In 1901, thomas edison invented the nickel-iron battery. the following reaction takes place in the battery. fe(s) + 2 nio(oh)(s) + 2 h2o(l) fe(oh)2(s) + 2 ni(oh)2(aq) how many mole of fe(oh)2, is produced when 5.35 mol fe and 7.65 mol nio(oh) react?
