What is the separation method of sawdust and pebbles?
The separation method of sawdust and pebbles can be effectively achieved using a technique called filtration or sieving. In this process, a sieve or mesh with holes smaller than the size of the pebbles but larger than the sawdust particles is used. By pouring the mixture onto the sieve, the sawdust passes through while the pebbles are retained, allowing for an efficient separation. Another method could involve using water, where the sawdust floats and can be skimmed off, leaving the pebbles behind.
When particles of a mixture that are not joined together what is this called?
When particles of a mixture are not joined together, it is called a heterogeneous mixture. In a heterogeneous mixture, the individual components remain distinct and do not combine to form a new substance. Examples of heterogeneous mixtures include a mixture of oil and water or a combination of sand and iron filings.
Why it is called chromatography separation?
Chromatography is called a separation technique because it separates different components of a mixture based on their different affinities for the stationary phase (solid or liquid) and the mobile phase (gas or liquid). As the mixture passes through the stationary phase, the components interact differently and move at different rates, leading to separation.
What separation technique relies on the components of a mixture settling into layersration technique relies on the components of a mixture settling into layers?
The separation technique that relies on the components of a mixture settling into layers is called sedimentation. In this process, denser particles settle at the bottom of a container due to gravity, forming a distinct layer, while lighter components remain above. This technique is often used in water treatment, mining, and various laboratory applications to separate solids from liquids. Following sedimentation, decantation can be employed to remove the upper layer without disturbing the settled material.
What is the reaction between sulfuric acid and iron filings called?
chemical reaction.

How would you separate gold from a mixture of gold and copper filings?
One method to separate gold from a mixture of gold and copper filings is by using a process called gravity separation. This involves shaking the mixture in water to allow the gold, being denser, to settle to the bottom while the lighter copper filings float on top. The separated gold can then be carefully collected and dried.
What is the method called that is used to separate sawdust from water?
Filtration is the most simple method.
Is powdered sulphur and iron filings a solution or a mixture?
Solutions are a type of mixture, so it's not really an either/or thing. However, in order to be considered a solution, the mixture must be homogenous, and a mixture of sulfur and iron filings is decidedly not homogeneous on a microscopic level. So it's (just) a mixture, not the specific type of mixture called a solution.

The technique of separating gold from a mixture of gold dirt and sand is called?
Panning.
Is the mixture of iron and sulfur can be separated?
Yes, a mixture of iron and sulfur can be separated by using a magnet to attract the iron filings and then using a process called sublimation to separate the sulfur from any remaining particles.
A mixture is made of different materials that can easily be separated.?
heterogeneous
How do you separate a mixture of limestone and sawdust and wood chips and potassium nitrate?
One way is to use a process called sieving to separate the larger wood chips from the smaller particles of limestone, sawdust, and potassium nitrate. The sawdust and wood chips can be separated by flotation since sawdust floats while wood chips sink in water. Finally, the potassium nitrate can be dissolved in water and then filtered to separate it from the limestone.
What is the Method called when you separate sawdust from the air?
It is called filtering.
Two or more substances that have been combined but not chemically changed.?
A mixture is formed when two or more substances are combined physically but retain their individual properties. The components in a mixture can be separated by physical means, such as filtration or evaporation.
Why it is called chromatography separation?
Chromatography is called a separation technique because it separates different components of a mixture based on their different affinities for the stationary phase (solid or liquid) and the mobile phase (gas or liquid). As the mixture passes through the stationary phase, the components interact differently and move at different rates, leading to separation.
