When I2 and FeCl2 are mixed together, iodine (I) cannot replace chlorine (Cl) in the compound because iodine is lower on the per
andrezito [222]

The given statement is True.


This is single replacement reaction.

As reactivity decreases down the group,

Iodine is less reactive than Chlorine.  

And so Iodine cannot replace chlorine from FeCl2.

I2 + FeCl2 ---> no reaction (Iodine is less reactive than chlorine)

En la electrosis del cloruro de sodio (Na Ci) el cloruro es atraido por elcatodo. Falso o verdadero. Y porque?
hram777 [196]

Answer:

Falso

Explanation:

La electrólisis es la descomposición de una solución cuando la corriente continua se pasa a través de ella.

La corriente entra y abandona el electrolito a través de los electrodos. El electrodo positivo se llama el ánodo mientras el electrodo negativo se llama cátodo.

Los iones positivos se mueven hacia el cátodo, mientras que los iones negativos se mueven hacia el ánodo.

Dado que el cloruro es un ion negativo, se mueve hacia el ánodo y no hacia el cátodo.

1) What happens when the pressure above the surface of a liquid is equal to the vapor
xenn [34]

When the atmospheric pressure is equal to the vapor pressure of the liquid, boiling of liquid will begin.

<h3>What happens when atmospheric pressure is equal to the vapor pressure of liquid?</h3>

When the atmospheric pressure is equal to the vapor pressure of the liquid, boiling will begin. The bubbles formation started to the liquid molecules which have gained enough energy to change to the gaseous phase.

The vapor pressure of ethanol is 5.95 kPa at 20.0 °C, and its vapor pressure is 53.3 kPa at 63.5 °C.
