Calculate the pH of the solutions, given the following [H+], and then identify the solution asacidic, basic, or neutral. [H+] = 7.6 x 10-8 M

How many moles of potassium hydroxide are needed to completely react with 2.94 moles of aluminum sulfate

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 .

Calculate the percent composition by mass of each element in al(oh)3. use at least three significant figures.
