the components of substances that are ......... separate when the substance is placed in water

# Explanation:## Step1: Understanding the Question### The question is asking about the type of substances that separate into their individual components when placed in water. This is a fundamental concept in chemistry, particularly in the study of solutions and mixtures.## Step2: Identifying the Type of Substances### There are several types of substances that can separate into individual components when placed in water, including ionic compounds, acids, and bases. However, not all of these substances will separate in the same way.## Step3: Determining the Correct Answer### Among the types of substances that can separate in water, ionic compounds are the most likely to do so. This is because ionic compounds are made up of positively and negatively charged ions, which are held together by strong electrostatic forces. When an ionic compound is placed in water, the polar water molecules are able to break these forces and separate the ions.# Answer:### Ionically bound
