Yes.
Heat the salt and sand mixture up until the salt melts. Filter the sand out of the salt. Melting is a physical change and filtration is a physical separation technique so the separation is entirely physical.

∙ 11y agoYes. If the salts are shaken around a lot, then the bigger salts will fall to the bottom, and the smaller salts will stay on top. This is a physical process.

Why is matter a pure substance?
Matter is a pure substance if it can only be separated by chemical means, NOT physical means. This could be a compound or an element. The opposite is a mixture which can be separated/broken into smaller parts by physical means.
Can elements be separated into smaller parts using chemical means?
No. An Element is an atom. An atom is the smallest particle. Atoms cannot be broken down into smaller things. Ever.
What sample of matter can be separated into different substances by chemical means?
Anything larger than a single atom. Compounds -- that is, substances chemically made from more than one species of atom -- can be chemically separated into their elemental parts. H2O can be seperated by electricity into H2 and O2. 2(H2O) + charge --> 2H2+O2
How biologist get DNA out of the cell?
DNA can be extracted from most cells by a simple chemical procedure: the cells are opened and the DNA is separated from the other cell parts.
Is it true that the parts of a mixture can be separated?
But of course. If you shake up soil and water to make a mixture you can separate it out by filtering it. I would imagine that you could separate all mixtures.

Why can't elements be separated into smaller parts using chemicals means?
Two reasons: # Smaller than a single atom of an element, it ceases to be an element. # The energies available to chemical means is a million times too small to break apart an atom of an element (the nucleus) to "smaller parts".
What is the building block of all matter that cannot be separated into parts by chemical means?
no possible answer

Is cereal an element?
No, the definition of an element is a substance that can't be separated into smaller parts.
Relationship between a mechanical mixture and properties?
A mechanical mixture is a mixture in which the components can be separated by mechanical means. In other words, there is no chemical bonding. The parts keep their own properties and chemical make up.
What are some different types of matter made up of?
A substance can be categorized into several categories. If a substance cannot be separated through physical means (e.g., distillation, magnetism) it is a pure substance. If a substance can be separated through physical means, it is a mixture. If a mixture is uniform throughout, it is a homogenous mixture, like saltwater. If it is not (i.e., there are different parts to it, like a can of soda), it is a heterogeneous mixture. If a pure substance can be separated through chemical means, it is a compound, like glucose, which is made of carbon, oxygen, and hydrogen. If a substance cannot be separated by chemical means, it is an element, like oxygen, which is made of just oxygen. A substance can be in multiple categories.
What is the main trait of a simple mixture of particles?
It can be separated into its parts. It can be separated into its parts.

Why is an insect called an insect?
It comes from the latin word insectum, which means 'in parts.' This refers to how the body parts are separated and look like they have been chiseled out.
