Due to the properties of sand, when we heat it over Bunsen burner it can be used as heating buffer. The sand would absorb heat even after it is removed so we can use it similarly to a hot water bath but the sand will eventually cool down and need reheating. It is common to use this sand heat bed technique in organic laboratories or when gentle/slow heating is required.
Yes, when heated with a Bunsen burner, sodium carbonate (Na2CO3) decomposes to form sodium oxide (Na2O) and carbon dioxide (CO2).
Robert Bunsen invented the Bunsen Burner in 1867.
No, a Bunsen burner is typically made of metal, specifically brass or stainless steel. Pyrex is a type of borosilicate glass that is commonly used for laboratory glassware such as beakers and test tubes.
Nothing! but if you keep it in for a while, the flame turns orange
Robert Bunsen collaborated with his laboratory assistant, Peter Desaga, to develop the Bunsen burner in the 1850s. Desaga was responsible for constructing the burner based on Bunsen's design and ideas.
Many salts do not decompose when heated.

Sodium Carbonate
Silicon dioxide (SiO2), commonly known as quartz, does not decompose when heated with a Bunsen burner. This is because SiO2 has a very high melting point, around 1,710°C, which is above the typical temperature of a Bunsen burner flame. Instead of decomposing, it stays solid and retains its structure.
Certain metals, such as gold and platinum, do not decompose when heated with a Bunsen burner due to their high melting points and chemical stability. These metals do not react with oxygen in the air at the temperatures typically achieved with a Bunsen burner, allowing them to maintain their integrity without decomposing.

Robert Bunsen invented the Bunsen burner if that is what you mean?
Tungsten is a metal that does not decompose when heated with a Bunsen burner due to its high melting point of 3422°C. This property makes tungsten ideal for use in the filament of incandescent light bulbs.

the iron ring, the wire mesh over the ring, the beaker or whatever else was being heated. There are special tongs for most types of glassware or porcelain objects that are heated over a Bunsen burner.
because Robert Bunsen made it :)
