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!

Determine which equations you would use to solve the following problem: Calculate the amount of heat needed to change 20.0 g of
Inessa [10]

Answer:

Q = 4019.4 J

Explanation:

Given data:

Mass of ice = 20.0 g

Initial temperature = -10°C

Final temperature = 89.0°C

Amount of heat required = ?

Solution:

specific heat capacity of ice is 2.03 J/g.°C

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = T2 - T1

ΔT =  89.0°C - (-10°C)

ΔT = 99°C

Q = 20.0 g ×2.03 J/g.°C × 99°C

Q = 4019.4 J
