What volume of oxygen is required for the complete combustion of C2H2?
According to reaction, At STP; 1 mole of acetylene that is 22.4L require 5/2 moles of oxygen that is 52×22.4 = 56L for complete combustion.
What is the name of C2H2?
Ethyne
Is C2H2 sp3 hybridized?
Answer: Since C2H2 is a linear molecule the C must be sp. Also only sp carbon can form a triple bond. sp2 carbon would give a trigonal planar arrangement. The O in HOCl has two lone pairs and two bonding pairs in a tetrahedral arrangement which is sp3.
What is C2H2 used for?
It is a colourless, inflammable gas widely used as a fuel in oxyacetylene welding and cutting of metals and as raw material in the synthesis of many organic chemicals and plastics; its chemical formula is C2H2. Acetylene torch being used to cut steel.
How many lone pairs does C2H2 have?
Note: A total of six valence electrons is used to form a triple bond between both the Carbon atoms. In Lewis structure of C2H2, the octets of all the atoms are complete, and there are no lone pairs of electrons in the molecule.
What is the hybridization of C2H2?

What is the formula for Ethyne?
C2H2
Does C2H2 dissolve in water?
Its melting point is -81.8°C. It bypasses the liquid state in solidifying. Its density is 1.171 kg/m3 (at ρ = 101.3 kilonewtons per sq m [kN/m2] or 760 mm of mercury and t = 0°C); it is only slightly soluble in water and very soluble in acetone (at 15°C, 25 parts of acetylene to 1 part of acetone).
Does Cao dissolve in water?
Water
Does acetylene burn without oxygen?
Decomposition is a chemical reaction whereby acetylene breaks down into its constituent elements, carbon and hydrogen. This reaction gives out a great deal of heat, which can cause the gas to effectively ignite without the presence of air or oxygen.
Does oxygen or acetylene open first?
We recommend closing the oxygen valve first whenever turning off an oxy-fuel torch system especially when Acetylene is fuel. This is only part, but a very important part, of the complete safe operating procedure recommended for torches by Harris.
