Why a beaker containing sand and water is a mixture although sand itself is a pure substance?

Sand is not a pure substance - it can be a mixture of almost countless compounds. Sand and water is a mixture although, chemically speaking, the term mixture tends to be reserved for mixtures of components that are the same phase.

However, the water, if it is distilled, is a pure substance with the chemical formula of H2O. The mixture of water and sand is a heterogeneous mixture because it is not the same throughout. Pure substances can be mixed together to create solutions or heterogeneous mixtures, because not all substances react with each other to form new substances. Mixtures, especially the solutions used in science classes, are often mixtures of pure substances.

Is a beaker of lake Ontario water a compound?
No. It would be a mixture containing not just the compound water, but dissolved salts and other minerals.
How do you remove sand from a mixture in a beaker?
Type your answer here... filter the mixture
When you out salt and water together in a beaker you cause them to form a?
A useless mixture is obtained.
Should we measure the mass of a beaker before measuring a chemical or powder inside the beaker?
You can do that or you can zero balance the scale with the empty beaker on it before adding the substance to be measured to the beaker.
What is the function of beaker?
the beaker is used for measuring liquids and chemicals during experiment...
Explain Why a beaker containing sand and water is mixture although sand itself is a pure substance?
Because you mixed sand and water together in the beaker.
Why is a beaker containing sand and water considered a mixture?
Anything containing two separate entities is a mixture. Sand and water is a heterogeneous mixture because it is not the same throughout.
Is a beaker of lake Ontario water a compound?
No. It would be a mixture containing not just the compound water, but dissolved salts and other minerals.
Mass by difference?
mass by difference is an indirect way to find the mass of an object. For example, if you know the mass of a 'beaker and the substance in it' and the 'mass of the beaker', you can determine the mass of the substance by subtracting (mass of beaker + substance) - (mass of beaker)
What happens when an object is dropped into a beaker containing a liquid and then the object drops to the bottom of the beaker?
The density of the object is at least equal to, and possibly greater than, the density of the liquid in the beaker.
How do you remove sand from a mixture in a beaker?
Type your answer here... filter the mixture
If a beaker contains glucose and is permeable to glucose what will happen to the glucose?
If a beaker containing glucose is permeable to glucose, then the glucose will go through the beaker.
What you use a beaker for in science?
Containing liquids that are possibly harmful.
What is a beaker for in science?
A beaker is used to contain a liquid substance either chemical or water based.
When you out salt and water together in a beaker you cause them to form a?
A useless mixture is obtained.
How do you test for monosaccarides?
You place Benedict's solution (blue solution) and the unknown substance (possibly containing monosaccarides) into a beaker and then heat it for approximately 5 minutes. If the substance contains monosaccarides, the solution will turn from blue to orange.
What is there a different level between pipette and beaker?
in beaker the substance that contains is largely transpearable ,but in pippette the substance tat contain is transparable only drop-wise
