Zinc is part of group 12 on the periodic table, and its atomic number is 30. It is a silver or gray metal typically mined in ores. It has been used to make brass, an alloy of copper and zinc. Valence Electrons:The electrons in the outer shell of an element are called the '...
How many liters of hydrogen at STP can be produced by the reaction of 4.15 g of zinc with hydrochloric acid: Zn + 2HCl \to ZnCl_2 + H_2 Consider the balanced reaction given below. 3ZnCl2(g) + 2Al(s) arrow 2AlCl3(g) + 3Zn...
Initially Z-selective alkyne semihydrogenation occurs as the reaction vessel is warming. Formation of E-stilbene is observed when the temperature reaches 80C after 90 minutes, and after several hours the E-stilbene is the major product. The ReactIR data suggests that two different mechanisms occur....
