Which of the following is not a true statement? o a metal ion can form a complex with water, thereby increasing water's acidity. o a metal ion can make a reaction center more susceptible to receiving electrons o a metal ion can make a leaving group a weaker base. o metal-bound hydroxide is a poorer nucleophile than water. 0 the pka of a metal-bound water depends on the metal ion.

In this chemical reaction, 325 grams of barium (ba) react completely. how many moles of lithium (li) are produced?

Light waves can move through , but they travel fastest when they move through a(n) .

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .
