Answer:
78.12g of acetylene
Explanation:
Acetylene and calcium hydroxide are produced when H₂O reacts with CaC₂. The reaction is:
2 H₂O + CaC₂ → C₂H₂ + Ca(OH)₂
<em>Where 1 mole of C₂H₂ (acetylene) is produced per mole of CaC₂</em>
Thus, the addition of 3 moles of CaC₂ produces 3 moles of acetylene.
As molecular mass of acetylene is 26.04g/mol, grams of acetylene produced are:
3mol C₂H₂ × (26.04g / mol) = <em>78.12g of acetylene</em>

<span> Son organismos que pertenecen al Nivel de Organización Protoplasmático. Son UNICELULARES y se distinguen por no poseer un Núcleo bien organizado. Son PROCARIOTAS porque el material genético (ADN o Cromosomas) al no tener Carioteca o Membrana Nuclear, se encuentran dispersos en el Citoplasma. Comprenden a las Cianofíceas y Bacterias. Las Cianofíceas o Algas verde azuladas son Autótrofos, ya que realizan la Fotosíntesis y algunas Bacterias se nutren por Absorción, ya sea descomponiendo a sustratos orgánicos como las Saprófitas, o infectando a un organismo vivo y viviendo a expensas de él como las Parásitas y otras son Heterótrofas y Autótrofas. Poseen un Sistema de Nutrición AUTÓTROFA, HETERÓTROFA y por ABSORCIÓN. Las Bacterias son Células muy pequeñas, que tienen Reproducción Asexual por Fisión Binaria. Tienen Pared Celular porosa. Presentan diferentes Formas (Cocos, Bacilos, Espirilos, Vibriones). Producen Enfermedades (Tuberculosis, Lepra, Sífilis, Neumonia, etc.) Hay Bacterias Beneficiosas (Producción de alcohol y vinagre, quesos, yogurth, etc.). Las CIANOBACTERIAS poseen CLOROFILA y un Pigmento azul llamado FICOCIANINA. Pueden estar libres o en colonias. </span>
