Are the following electrolytes or non-electrolytes?

1) CH3CH2CH2OH
2) Mg(OH)2
3) H3CO4CH3

It would help us if you kept the same screen name; Margaret, Rena, John, Alicia, etc are confusing AND it doesn't get your answers any faster In fact, it slows them down AND you don't always get the best answer because we can't do the proper follow up.

1 is non.
2 is an electrolyte BUT it isn't very soluble.
3. I don't know what this one is. But probably it is non.

To determine whether a compound is an electrolyte or non-electrolyte, you need to consider whether it dissociates into ions when dissolved in water.

1) CH3CH2CH2OH (also known as ethanol) is a covalent compound and does not dissociate into ions when dissolved in water. Therefore, it is a non-electrolyte. To determine this, you can consider the fact that ethanol is a molecular compound made up of carbon, hydrogen, and oxygen atoms. Molecular compounds usually do not dissociate into ions when dissolved in water.

2) Mg(OH)2 (magnesium hydroxide) is an ionic compound and does dissociate into ions when dissolved in water. Magnesium hydroxide breaks down into magnesium ions (Mg2+) and hydroxide ions (OH-) in solution. Therefore, it is an electrolyte.

3) H3CO4CH3 does not represent a specific compound. It seems like a combination of molecular formulas for organic compounds, but without further information, it is difficult to determine whether it is an electrolyte or non-electrolyte. If you provide more details about this compound, I can help determine its properties.
