En las salinas de Manaure se procesa la mayor cantidad de sal que se consume en Colombia, este proceso se conoce como evaporación, ya que mediante el calor se evapora el agua y solo queda un remante. Si una solución de NaOH (hidróxido de sodio) se hace reaccionar con H3PO4 (ácido fosfórico)y luego la solución resultante es evaporada por secamiento, podríamos decir: A Ocurre una reacción de sustitución.
B Ocurre una reacción de neutralización.
C El producto es una sal y se denomina fosfato fosfórico.
D El producto es una sal y se denomina ácido fosfórico.

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90

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 .
