It is due to two reasons, 1- C-C short bond length which is responsible to almost localized the pi electrons between two nuclei and to decrease the electron density at opposite side of both nuclei and 2- sp1 hybridized orbitals of carbon which are responsible to attract the electron pair of C-H bond.
What else can I help you with?
Why are H atoms of acetylene slightly acidic and replaceable by metals like Na or Ag while H atoms of ethylene are not?
The H atoms in acetylene are slightly acidic because they are attached to a sp-hybridized carbon, leading to more s-character in the C-H bond, making it more polarized and thus easier to remove. In contrast, the H atoms in ethylene are attached to sp2-hybridized carbons, which have less s-character in the C-H bond, making them less acidic and not easily replaced by metals like Na or Ag.
What is a reaction between acetylene and oxygen that is used in welding metal?
The reaction is called oxyacetylene combustion. It involves the burning of acetylene gas (C2H2) and oxygen (O2) to produce a high-temperature flame used for welding and cutting metals. The reaction forms carbon dioxide (CO2) and water vapor (H2O) as byproducts.
What are properties on non metals and examples?
non metals give acidic oxides e.g S,Cetc
Are alkali metal and alkaline earht metals similar?
Alkali metals and alkaline earth metals are both groups of elements found in the periodic table. They have similar characteristics in that they are both highly reactive, low-density metals with low melting points. However, alkali metals are located in group 1 of the periodic table, while alkaline earth metals are located in group 2, and they have different chemical properties and reactivities.
If a reaction occurs when a piece of metal is placed in a solution what can you conclude about the solution?
It is acidic because bases rarely react with metals.
Why are H atoms of acetylene slightly acidic and replaceable by metals like Na or Ag while H atoms of ethylene are not?
The H atoms in acetylene are slightly acidic because they are attached to a sp-hybridized carbon, leading to more s-character in the C-H bond, making it more polarized and thus easier to remove. In contrast, the H atoms in ethylene are attached to sp2-hybridized carbons, which have less s-character in the C-H bond, making them less acidic and not easily replaced by metals like Na or Ag.
Is carbon dioxide an acidic gas?
Yes it is. All the oxides of non-metals are acidic and oxides of metals are basic
What is the industrial use of acetylene?
Acetylene uses:- welding- metals cutting- feedstock for plastics and acrylic products fabrication
Why can acetylene torch be used to weld metals together?
Acetylene torches can be used to weld metals together because they have a higher temperature than the metal's melting point.
What is acetylene welding?
Acetylene welding is a process that involves using acetylene gas as a fuel combined with oxygen to produce a high-temperature flame for joining metals together. The flame generated by burning acetylene with oxygen can reach temperatures up to 3,100 degrees Celsius, making it effective for welding tasks.
Can a metal dissolve into a liquid?
Yes. Metals can be dissolved into liquid solutions. Several metals can be dissolved in acidic media such as HNO3 to prepare acidic solutions of these metals.
What gases do mechanics use for heating metals during welding?
mixture of oxygen and acetylene (oxyacetylene)
Is sulfur dioxide acidic?
This is because sulphur dioxide is an acidic oxide. Acidic oxides are formed from non-metals.
Why do some trace metals require nitrous oxide acetylene flame instead of air acetylene flame?
Nitrous oxide acetylene burns at a higher temperature than air acetylene. You'd really need to ask a metallurgist (someone who know just about everything to do with metals) to get the real answer, but basically some metals are harder than others. The harder the metal, the harder it is to cut with fire. Brass and gold are very soft, while iron and titanium are hard.
WHAT IS THE DEFINITION OF HACK SAW?
The hacksaw is a saw for cutting metals. It has a very fine tooth, replaceable blade.
Are oxides of non -metals acidic or basic and why?
Oxides of non-metals are typically acidic because they react with water to form acidic solutions. This is due to the presence of non-metallic elements which have a tendency to gain electrons and form acidic compounds when combined with oxygen.
Why can an acetylene torch be used to weld metals together?
it is an alkyne that burns at about 3500 degrees Celsius, much higher then most metals melting point.
