9. 50.0 g of iron (Fe) that has an initial temp of 225.0°C and 50.0 g of gold (Au) that has an initial temperature of 25.0°C are brought into contact with one another. Assuming no heat is lost to the surroundings, what will
the final temperature be when the two metals reach thermal equilibrium?

Easy definition for atom and atomic mass

For the following dehydrohalogenation (e2) reaction, draw the zaitsev product(s) resulting from elimination involving c3–c4 (i.e., the carbon atoms depicted with stereobonds). show the product stereochemistry clearly. if there is more than one organic product, both products may be drawn in the same box. ignore elimination involving c3 or c4 and any carbon atom other than c4 or c3.

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?
