How many moles of water are produced from 19.2 g of B2H6
lbvjy [14]
The Balanced chemical equation of reaction of Borane with oxygen is as follow,
                                  B₂H₆ + 3O₂ -----> 2HBO₂ + 2H₂O
According to this equation 27.66 g (1 mole) of B₂H₆ reacts with oxygen to produce 36 g (2 moles) of water.
The amount of water produced when 19.2 g of B₂H₆ reacted is calculated as follow,
\frac{27.66 g B2H6 produced}{19.2 g of B2H6 will produce} = \frac{36 g of H2O}{x g of water}
Solving for x,                       
              x = (36 g of H₂O ₓ 19.2 g of H₂B₆) / 27.66 g of B₂H₆

              x = 24.98 g of H₂O

Result:
           24.98 g 
of water is produced when 19.2 g of B₂H₆ is reacted with excess of oxygen.

Identify what type of reaction is below. Also determine what coefficients that would balance the chemical equation. ___ HCl + __
egoroff_w [7]

Answer:

Single Replacement; 2, 1, 1, 1

Explanation:

2HCl + Zn → H2 + ZnCl2

In a single replacement reaction, one specie is replaced by another specie in a chemical reaction.

If we look at the reaction above, zinc metal reacted with hydrochloric acid. The reaction proceeds in such a manner that zinc replaces hydrogen in hydrochloric acid. This is a single replacement reaction because only one chemical specie is displaced in the reaction.

Estructura correcta de los siguientes compuestos e indique si el nombre está escrito de forma correcta; 1,4-ciclohexadieno
Makovka662 [10]

Answer:

En la imagen adjunta.

Explanation:

¡Hola!

En este caso, dados los lineamientos IUPAC que tenemos en cuenta para dibujar la estructura de hidrocarburos cíclicos, para el 1,4-ciclohexadieno, es posible determinar que esta estructura viene dada por hexágono que representa el ciclohexano y dos dobles enlaces en los carbonos 1 y 4 al ser un dieno. Por lo anterior, en la imagen adjunta, puede encontrar la estructura requerida.

¡Saludos!
