How many moles of Co2 will be produced from the reaction of three moles of acetylene with excess oxygen?
Since acetylene (C2H2) has a stoichiometry of 2 moles of acetylene to produce 2 moles of CO2, three moles of acetylene would produce 3 moles of CO2. The reaction with excess oxygen ensures that all the acetylene is fully converted to CO2.
What element is used in oxy-acetylene flame?
The element used in an oxy-acetylene flame is carbon. Acetylene gas acts as the fuel, while oxygen is used as the oxidizer in the flame. The high temperature resulting from the combustion of acetylene and oxygen produces a clean and precise flame that is commonly used in cutting and welding applications.
What is the oxygen to acetylene ratio in oxidising flame?
The ideal ratio of oxygen to acetylene in an oxidizing flame is around 1.1:1. This ratio helps ensure complete combustion of the acetylene, resulting in a clean and efficient flame with sufficient heat output for various welding and cutting applications.
Which compressed gases are used for welding?
Some common compressed gases used for welding include acetylene, argon, carbon dioxide, and helium. These gases are often used in various combinations depending on the welding process and materials being joined.
What reaction takes place during oxyacetylene gas welding?
During oxyacetylene gas welding, acetylene gas and oxygen are mixed in a torch and ignited to produce a high-temperature flame. The heat from this flame melts the metal being welded, while the oxygen assists in the combustion process by providing additional heat and reacting with the metal to form an oxide layer that is then removed as slag.
Which element is used in welding with oxygen?
Acetylene is commonly used in welding with oxygen to create a high-temperature flame for cutting and welding metal.
What are two gases used in oxy-acetylene welding?
You answered your own question. Oxygen and Acetylene. Other mixes are now used in place of Acetylene so the process is now called Oxy-Fuel.
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.
Why for welding use oxygen and acetylene?
Oxygen and acetylene are commonly used for welding because they create a high-temperature flame that can melt and join metals together effectively. The mixture of oxygen and acetylene provides a clean and precise flame, making it suitable for various welding applications. Additionally, the high heat produced by the oxy-acetylene flame allows for efficient welding of thick metal sections.
What is the flame commonly used in gas welding?
Oxy-Acetylene. A mixture of oxygen and acetylene. Commerically it is still acetylene, however, its chemical name is 'ethyne'. Its structure is 'H-C///C-H'. NB The symbol '///' repreent a triple bond between the two carbons.
Gas used in welding is what?
GASSES - Oxygen and Acetylene. Acetylene is sometimes replaced by a mixture of gasses. The Oxygen increases the burning rate/temperature of Acetylene and temperatures in excess of 6,000o F can be reached.
Which two gases mixed and used as fuel in welding?
n - Oxygen and Acetylene are the original gasses that are used for welding/cutting. Newer mixtures are slowly replacing Acetylene as a fuel. These gasses don't always reach the temperatures attained by Acetylene. Us old-timers still prefer Acetylene.
Which gas is use in gas welding?
oxygen and acetylene gas Argon gas is used in MIG and TIG welding
Which gasses used in normal welding process?
The gases commonly used in welding are oxygen, acetylene, argon, and carbon dioxide. These gases play different roles in the welding process, such as providing heat, shielding the weld from atmospheric contamination, and facilitating the arc.
What gases do mechanics use for heating metals during welding?
mixture of oxygen and acetylene (oxyacetylene)
What types of flame are obtained in oxy-acetylene gas welding?
When the correct amount of Oxygen is mixed with the Acetylene a NEUTRAL flame is produced. Less than that amount produces a CARBURIZING flame. Too much Oxygen creates an OXIDIZING flame. Most welding/cutting is done with a NEUTRAL flame but all flame adjustments have their purpose.
What are the three types of acetylene welding flames?
Mixing Acetylene and Oxygen in the correct proportions produces an extremely hot flame. Using just enough Oxygen so that the Acetylene is almost completely consumed in the flame is called a Neutral Flame. In most welding and cutting applications you would utilize this flame. Reducing the amount of Oxygen produces a Carburizing Flame. It is yellowish and not as hot as a Neutral Flame, but, is used in certain situations. Welding Aluminum is one. Increasing the Oxygen produces an Oxidizing Flame. It produces a flame that is pointed, colder, and louder than a Neutral Flame. It wastes fuel and isn't as efficient as a Neutral Flame.
