What is 2c2h2 5o2-4co2 2h2o?
It is the balanced equation for the combustion of acetylene (or ethyne).
What is the optimum ratio of air to ethyne for complete combustion?
The properly balanced combustion reaction is given by (don't care about N2 on the product side) C2H2 + 5/2 (O2 + 3.75N2) -> 2CO2 + H2O + N2 So, the molar air to fuel ratio for complete combustion is 2/5.
Does ethyne react with bromine?
Yes, ethyne (acetylene) can react with bromine to form 1,2-dibromoethane. This is an addition reaction where the bromine atoms add across the carbon-carbon triple bond in ethyne.
Another name for acetylene?
Acetylene (C2H2) is also known as ethyne. It is the simplest alkyne.
How ethyne is converted into ethane?
Ethyne (C2H2) can be converted into ethane (C2H6) by addition of hydrogen gas (H2) in the presence of a suitable catalyst, such as palladium or platinum. This process is known as hydrogenation and involves breaking the triple bond in ethyne and adding hydrogen atoms to form single bonds between carbon atoms in ethane.

What is the colour ethyne after combustion?
By combustion ethyne is transformed in carbon dioxide and water.
What happens when ethanol is burnt in air?
When ethanol is burned in air, it reacts with oxygen to produce carbon dioxide and water vapor. This is a combustion reaction that releases energy in the form of heat and light. The balanced chemical equation for the combustion of ethanol is C2H5OH + 3O2 → 2CO2 + 3H2O.
Why is ethane and air mixture not used for welding?
When ethyne is burnt in air, it gives a sooty flame. This is due to incomplete combustion caused by limited supply of air. However, if ethyne is burnt with oxygen, it gives a clean flame with temperature 3000°C because of complete combustion. This oxy-acetylene flame is used for welding. It is not possible to attain such a high temperature without mixing oxygen. This is the reason why a mixture of ethyne and air is not used. Hope its fine with u !! all the best !!
What is the equation for the reaction involved when the bromine is mixed with the ethyne?
The Nucleophilic substitution of Halo alkanes
What more dense oxygen or ethyne?
Oxygen is much more dense than ethyne. This is why a test tube full of ethyne would be held upside down so the ethyne doesnt escape into the air.
Is ethyne polar?
polar
What is the number of hydrogen atoms in a molecule ethyne?
The chemical formula of ethyne (acerylene) is C2H2 - two hydrogen atoms.
What molecules are nonpolar bromine pentafluoride tetrachloroethene chlorine trifluoride phosphine ethyne?
ethyne (or acetylene) is non polar
