To separate silicon from sand, you can use a process called "extraction." Silicon is typically found in sand in the form of silicon dioxide (SiO₂). Here's a common method to separate silicon from sand:
**Conversion to Silicon Tetrachloride (SiCl₄):**
Heat a mixture of sand (SiO₂) and carbon in the presence of a catalyst (usually copper) to produce silicon carbide (SiC).
[ SiO_2 + 3C \xrightarrow{\text{heat}} SiC + 2CO ]
React silicon carbide with chlorine gas (Cl₂) to form silicon tetrachloride (SiCl₄).
[ SiC + 2Cl_2 \rightarrow SiCl_4 + CCl_4 ]
**Distillation:**
**Reduction to Obtain Silicon:**
React silicon tetrachloride with hydrogen gas (H₂) to obtain silicon and hydrochloric acid (HCl).
[ SiCl_4 + 2H_2 \rightarrow Si + 4HCl ]
The silicon obtained in this step is typically in a powdered form.
**Purification:**
This process outlines a common method used in industry to extract silicon from sand. Keep in mind that industrial processes may vary, and the specific method used can depend on factors such as the required purity of the silicon and economic considerations.
Water and Boiling Water
You should be able to use a magnet to attract the iron out of the sand (silicon dioxide)
Yes, silicon is made of sand. At least it's in it.
Which one is mixture carbon dioxide = compound silicon = element silicon dioxide = compound or sand = mixture so sand is the answer.
Please refer to "How computer chips are made" to see that sand contains silicon in the form of silicon dioxide.

sand consists of silicon and oxygen
Silicon and Oxygen make up sand.

96,27 g of sand contain 45 g of silicon (if the sand is pure silicon dioxide).
sand is a compound, silicon dioxide.
It's the silicon chip in calculators and the other substance is sand. Sand is silicon dioxide. Hope that helped..
The element silicon is to be found in 'sand' which is made from quartz which is silicon dioxide.
