¿Cómo se escribe la fórmula molecular (orden de los iones)?
cluponka [151]

Answer:

A la izquierda el catión y a la derecha el anión.

Explanation:

¡Hola!

En este caso, y basado en las normas IUPAC para la escritura de las fórmulas moleculares, es necesario primero escribir el catión a la izquerda, seguido del anión a la derecha, tal y como se muestra en los siguientes ejemplos, recordando que el catión es el ion cargado positivamente y el anión, negativamente:

K^+Cl^-\\\\Ag_2^+(SO_4)^{2-}

Los cuales son cloruro de potasio y sulfato de plata respectivamente. También es necesario tener en cuenta que los metales tienden a ser cationes por su capacidad de perder electrones, mientras que los no metales a ganarlos y por ende resultar como aniones.

¡Un gusto ayudarte!

b. increase in surface area

<h3>Further explanation</h3>

Given

Speeding up a chemical reaction

Required

Factors used to speed up reactions

Solution

There are several factors that influence reaction kinetics :  

1. Concentration  

2. Surface area  

3. Temperature  

4. Catalyst  

5. Pressure  

6. Stirring  

Temperature is related to the kinetic energy of the particles. Heat is absorbed causes the particles of matter to move faster so that the reaction can take place faster

The enlarged surface area of the reactants causes more particles to react with other particles.

50 g square block of sulfur can be broken into small pieces or powdered so that more particles come into contact with each other
