2. Cuando se añade ácido clorhídrico sobre cinc se produce hidrógeno y cloruro de cinc. Suponiendo que se añade un exceso de ácido clorhídrico sobre 75 g de cinc con una pureza del 93%, calcular:
a) El volumen de hidrógeno que se obtendrá, medido a 27ºC y a una presión de 740 mmHg.
b) La masa de cloruro de cinc que se obtendrá.

Ase your answer to this question on the information below.hydrocarbons and fissionable nuclei are among the sources used for the production of energy in the united states. a chemical reaction produces much less energy than a nuclear reaction per mole of reactant.the balanced chemical equation below represents the reaction of one molecule of a hydrocarbon with two molecules of oxygen.chemical equation: ch4 + 2o2 → co2 + 2h2o + 1.48 × 10−18 jthe nuclear equation below represents one of the many possible reactions for one fissionable nucleus. in this equation, x represents a missing product.nuclear equation: write an isotopic notation for the missing product represented by x in the nuclear equation.
