Burka [1]3 years ago
4 0

Answer:

La tabla periódica de moseley fue una manera de dar solución a esta problemática, ya que nos permite tener a la mano todos los elementos que se han descubierto hasta la actualidad y sus propiedades químicas más resaltantes.

A continuación se Describe una linea del tiempo de la creación de la tabla periodica:

1820 -  se crean las tríadas de Dobereiner.  

1863 - se crea el cilindro de chancourtois.  

1864 - se crean las octavas de newlands.  

1869 - se crea el primer prototipo de la tabla periódica.  

1914 - se fórmula la ley periódica moderna por Moseley.

How much heat will a 45.00 g piece of glass require to change its temperature from 10 to 30 °C. The specific heat capacity is 0.
kolbaska11 [484]

Answer:

Q = 450 J

Explanation:

Given that,

Mass of a piece of glass, m = 45 g

The temperature changes from 10°C to 30°C.

The specific heat is 0.5 J/g°C

We need to find heat required to raise the temperature. The formula that is used to find it is given by :

Q=mc\Delta T\\\\Q=45\times 0.5\times (30-10)\\\\Q=450\ J

So, the required heat is 450 J. Hence, the correct option is (c).
