Escriba las fórmulas semi desarrollada y global correspondientes a: 2,3-dimetil-1-penteno
hammer [34]

Answer:

En la imagen adjunta.

Explanation:

Hola.

En este caso, debemos recordar que la fórmula semi desarrollada se relaciona con la fórmula estructural del compuesto orgánico a representar; de este modo, primeramente encontramos una cadena de cinco carbonos con un doble enlace en el primer carbono y dos radicales metil tanto en el segundo como en el tercer carbono. Por otro lado, la formula global muestra el tipo y número de átomos presentes en el compuesto, que para el dado, son siete átomos de carbono y catorce de oxígeno, según se puede observar en la imagen adjunta.

¡Saludos!

The enthalpy of combustion of n-octane, C8H18, is –4.79 × 107 J/kg. What is the enthalpy of combustion expressed in kJ/g?
SIZIF [17.4K]

Answer:

47,9 kJ/g

Explanation:

The enthalpy of combustion is the change in energy due the reaction of combustion of n-octane. If the enthalpy is -4,79x10⁷ J/kg And knowing (1000J = 1kJ) (1000g = 1kg). The enthalpy of combustion expressed in kJ/g is:

-4,79x10^7J/kg \frac{1kJ}{1000J} \frac{1kg}{1000g} = <em>47,9kJ/g</em>
