Calcular la cantidad en moles del tetraóxido de hierro que se pueden obtener a partir de 40 gramos de agua (90%) y 25 g de hierro sólido (98%), ademas, determine el porcentaje de rendimiento de la reacción 100 si en un laboratorio luego del proceso se obtuvieron 15 gramos del tetraóxido de hierro.

Which mathematical relationship should you us to convert moles of a substance into grams

Which of the following words describe the reality that the universe looks the same from various perspective

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 .
