What are three ways to break down a compound?
Compounds can be broken apart in chemical reactions called decomposition reactions. For example, water can be broken down into the diatomic elements hydrogen gas and oxygen gas in a chemical reaction called electrolysis. Sodium chloride can also be broken down into elemental sodium and chlorine gas by electrolysis.
What type of matter could be separated by physical methods?
A heterogeneous mixture is a mixture of two or more chemical substances (elements or compounds), where the different components can be visually distinguished and easily separated by physical means. Examples include: mixtures of sand and water. mixtures of sand and iron filings.
Which type of mixture can be separated by filtration and why?
Heterogeneous mixtures can be separated into their respective constituents. For example, a mixture of mud and water can be separated through filtration process easily, because water being liquid will pass through the filter paper easily but the mud will not because of it being solid. Was this answer helpful?
Can we separate the components of suspension?
A suspension is a mixture of solid particles in a liquid. They remain suspended because of their small size and the attractive forces of the liquid molecules. Separation can only be done if the particle sizes are increased to a size where they will precipitate from the solution.
What can Filtration be used to separate?
Filtration is used to separate an insoluble solid from a liquid. It is useful for separating sand from a mixture of sand and water, or excess reactant from a reaction mixture.
What is simple distillation used to separate?
Simple distillation is a method for separating the solvent from a solution. For example, water can be separated from salt solution by simple distillation. This method works because water has a much lower boiling point than salt.
What are the two stages of simple distillation?
Distillation involves 2 stages and both are physical state changes. (1) In simple distillation the liquid or solution mixture is heated to boil and vaporise the most volatile component in the mixture (liquid ==> gas). The ant-bumping granules give a smoother boiling action for the distillation process.
