A scuba tank of fixed volume is originally at a pressure of 50.0 atm and a temperature of 390 K. When it is placed near a fire pit in Eddie's yard, the temperature rises to 450 K. What is the new pressure of gas in the tank?

How many electrons does silver have to give up in order to achieve a sido noble gas electron configuration

Which statement best describes the flow of energy in this scenario

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 .
