A pot of water at 25°C is placed over a flame until it has boiled away. Which way is energy being transferred between the system
Hatshy [7]

Answer:

See explanation

Explanation:

According to the law of conservation of energy; energy is neither created nor destroyed but is converted from one form to another.

This means that energy can not be lost, we can trace the transfer of energy between a system and its surroundings.

When a pot of water at 25°C is placed over a flame until it has boiled away, energy is transferred from the pot (the system) to the surroundings hence the temperature of the surroundings rises accordingly.

1. Hidracidas a. MX

2 Acidas c. MHXO

3. Oxacidas  b. MXO

4. Basicas d. M(OH)X

Explanation:

¡Hola!

En este caso, de acuerdo con el concepto de sal, la cual está generalmente dada por la presencia de al menos un metal y un no metal, es posible encontrar cuatro tipos de estas; hidrácidas, oxácidas, básicas y ácidas, en las que las primeras dos son neutras pero la segunda tiene presencia de oxígeno, la tercera tiene iones hidróxido adicionales y la cuarta iones hidrógeno de más.

Debido a la anterior, es posible relacionar cada pareja de la siguiente manera:

1. Hidracidas a. MX

2 Acidas c. MHXO

3. Oxacidas  b. MXO

4. Basicas d. M(OH)XO

En las que M se refiere a un metal, X a un no metal, H a hidrógeno y O a oxígeno.

¡Saludos!
