which substance will most likely dissociate when it is dissolved in water?\no no₂\no n₂f₆\no cacl₂\no c₆h₁₂o₆
which substance will most likely dissociate when it is dissolved in water?\no no₂\no n₂f₆\no cacl₂\no c₆h₁₂o₆
Answer
Explanation:
Step1: Identify ionic and covalent compounds
Ionic compounds dissociate in water, covalent compounds generally do not. $NO_2$ is a covalent compound formed by non - metals nitrogen and oxygen. $N_2F_6$ is also a covalent compound made of non - metals nitrogen and fluorine. $C_6H_{12}O_6$ (glucose) is a covalent organic compound. $CaCl_2$ is an ionic compound as it is formed by a metal (calcium) and non - metals (chlorine).
Step2: Recall dissociation property
Ionic compounds dissociate into ions in water. $CaCl_2$ dissociates into $Ca^{2 + }$ and $2Cl^{-}$ ions in water.
Answer:
C. $CaCl_2$
