En una práctica experimental, para la obtención de cloruro cobaltoso, se hacen reaccionar 120 g de sulfuro cobaltoso de 60% de p

ureza con 30 cm3 de ácido nítrico concentrado (densidad 1,142 g/cm3, 69,8% en peso de HNO3), en presencia de ácido clorhídrico concentrado (densidad 1,19 g/cm3, 37,33 % en peso de HCl). Calcular:
a) El volumen de ácido clorhídrico concentrado que se requiere para la reacción.
b) La cantidad máxima de cloruro de cobalto (II) que se puede preparar.
c) El número de moléculas de monóxido de nitrógeno que se deprenden.
d) El número de átomos de azufre que se forman.
e) El número de moles de agua que se obtiene.

Write a balanced chemical equation for the complete combustion of C3H7BO3, a gasoline additive. The products of combustion are C
nexus9112 [7]

Answer:

2C₃H₇BO₃ + 8O₂ → 6CO₂ + 7H₂O + B₂O₃.

Explanation:

  • For balancing a chemical equation, we should apply the law of conversation of mass. It states that the no. of atoms in the reactants side is equal to that of the products side.

So, the balanced equation:

<em>2C₃H₇BO₃ + 8O₂ → 6CO₂ + 7H₂O + B₂O₃.</em>

It is clear that 2.0 moles of C₃H₇BO₃ is completely burned in 8 m oles of oxygen and produce 6 moles of CO₂, 7 moles of H₂O and 1 mole of B₂O₃.
