Cement sand limestone and sodium carbonate make what?
It makes glass!!
What does cement mixed with sand limestone and sodium carbonate make?
It makes glass
Where does molten carbonate come from?
Sodium carbonate can be made by the Solvay process from brine (sodium chloride) and limestone (calcium carbonate). In the US there are large deposits of a mineral called Trona which is sodium bicarbonate carbonate, and it is obtained from that. Potassium carbonate is made by electrolysis of potassium chloride which is found as mineral Sylvite, which gives potassium hydroxide which is then carbonated with CO2. See wikipedia entries for Solvay Process, Trona, and Potassium Carbonate
What is chemical is NaCO2?
Na2CO3 is commonly known as Sodium Carbonate.
Is sodium carbonate the same as sodium bicarbonate?
No. Sodium carbonate is Na2CO3. Sodium bicarbonate is NaHCO3. Sodium carbonate is a stronger base.
What are industrial alkalis?
They are alkalis, such as sodium carbonate, used by industries, such as glassmakers.
What is the role of sodium carbonate in the preparation of glass?
The typical glass (a sodium and calcium silicate) result from the melting of silicon dioxide, sodium carbonate and calcium carbonate; sodium carbonate ia a chemical reactant here but also help to reduce the melting point of SiO2.
Is baking soda limestone?
Baking soda is sodium bicarbonate (also called sodium hydrogen carbonate) NaHCO3 Limestone is Calcium carbonate CaCO3. These are very different substances, chemically and physically.
Limestone plus sand plus sodium carbonate equals?
Glass
Cement sand limestone and sodium carbonate make what?
It makes glass!!
What is Bicarbonate soda made from?
Salt (sodium chloride) and limestone (calcium carbonate).
What does cement mixed with sand limestone and sodium carbonate make?
It makes glass
What do you heat limestone with to make glass?
Glass is made by heating a mixture of limestone, sand and sodium carbonate. As glass is a mixture of calcium silicate and sodium silicate.
What is glass made up of?
Heating Limestone with sand and sodium carbonate makes glass
What glasses made up of?
Heating Limestone with sand and sodium carbonate makes glass
What are 3 chemicals that don't form a liquid?
Examples: calcium carbonate, potassium carbonate, sodium carbonate. These compounds are decomposed before melting.
When limestone is heated with sand and sodium carbonate it makes which important material?
It creates Glass! : D
