Distinguish between an oxidising flame and a carburising flame in oxy- acetylene welding?
Basically, you need to look at the flame itself, if the tip of the nozzle is bluish/white, and long , then the flame is a carburising or reducing flame, it contains a high ratio of acetylene compared to oxygen, and will produce a cooler sooty flame. this can be used to make metals more malleable when working them, but the carbon is not helpful, and cannot be used for welding operations
An oxidising flame is more pupleish/white and is far hotter, with more oxygen than acetylene, this flame is used in cutting, but will harden steel, making it brittle.
in between the two is the neutral flame where welding operations are carried out.

Which one is oxidising between sodium an chlorine?
chlorine is oxidising
How many covalent bonds are there between carbon atoms in acetylene?
There are three covalent bonds between carbon atoms in acetylene, as acetylene has a triple bond between the two carbon atoms.
What is difference between acetylene and formaldehyde?
Oxygen is a chemical element, acetylene is an organic chemical compound.

What type of formula where the atoms are in the smallest whole number ratio?
It is a poor chemical formula. Poor, because it would not distinguish between acetylene C2H2 and benzene C6H6 for example. It is useful only to the extent that it shows the proportions of the atoms in molecule of the compound.

What type of thread is used on the acetylene supply?
Acetylene is typically supplied through a specialized type of thread known as a CGA 510 connection. This thread type ensures a secure and leak-free connection between the acetylene supply tank and the regulator or other equipment being used.
What kind of chemical change turns to produce acetylene gas?
The chemical change that produces acetylene gas is the reaction between calcium carbide (CaC2) and water. This reaction forms calcium hydroxide (Ca(OH)2) and acetylene gas (C2H2).
What is Size difference between oxygen and acetylene cylinder?
Oxygen cylinders are typically larger and heavier than acetylene cylinders due to the higher pressure at which oxygen is stored. Oxygen cylinders may also contain more volume of gas compared to acetylene cylinders.
