What is chemical equation for acetylene being burnt during some acetylene welding?
There are several reactions that will produce acetylene. The two used commerically are the cracking of petroleum which involves several reactions but the other is reacting calcium carbide with water. Calcium carbide is first produced in a blast furnace with limestone (calcium carbonate) and coal. When it is reacted with water the reaction is CaC2 + H2O -> CaO + C2H2 Calcium carbibe plus water -> calcium oxide and ethene (acetylene)
What else can I help you with?
What is a special type of sentence that show what happens during a chemical reaction?
a word equation, or a chemical equation
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.
Where is the new substance located in a chemical equation?
The new substance(s) formed during a chemical reaction will appear to the right of the "yield" arrow in an equation. This/these is/are the product(s) of the reaction.
What is shown on the left hand side of an equation in chemistry?
The left hand side of a chemical equation shows the reactants, which are the substances that are consumed or used up during a chemical reaction.
Does the arrow in a chemical equation mean gives?
Yes, the arrow in a chemical equation typically indicates the direction of the reaction and can be read as "reacts to form" or "yields." It shows the conversion of reactants into products during a chemical reaction.
How can you avoid electricity during welding?
By using insulating gloves and using gas welding instead of electric arc welding.
What gases do mechanics use for heating metals during welding?
mixture of oxygen and acetylene (oxyacetylene)
Purpose of oxy-acetylene welding?
You have oxygen and acetylene to blend into the tip for a flame. It will be regulated by adjusting the regulators on the bottles and the welding handle will have adjusting ability for the temperature you need for the metal you are welding.
What year did welding begin?
Welding began during the Bronze Age. Pieces were welded together by adding molten metal where they joined. Blacksmiths weld by heating and hammering pieces together. Oxy-acetylene welding began in the mid to late 1800s when oxygen was finally produced cheaply. Arc welding began in the early 1900s. TIG was designed to weld aluminum during WWII.
What is a special type of sentence that show what happens during a chemical reaction?
a word equation, or a chemical equation
What is the gas used in welding?
The most common gas used in welding is a mixture of argon and carbon dioxide, known as shielding gas. This gas helps protect the weld pool from contaminants in the air and stabilizes the arc during the welding process.
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.
How is oxygen used for gas welding?
Oxygen is used as active gas during MIG welding, spray transfer. It increases penetration and travel speeds. It is used only is small amounts though ususally 1%-5%. +++ The question mentioned "gas" welding, not any form of electric-arc process, and in oxy-acetylene and oxy-hydrogen welding the oxygen is necessary to raise the fuel-burning temperature to above the melting-point of steel.
What is the general formula of a chemical equation?
Generally it is REACTANTS ===> Products Symbollically it can be written as A + B = C + D Where 'A' & 'B' are the reactants and 'C' and 'D' are the products, NB All Chemical reactions obey the Law of CONSERVATION of MASS. So the total of the masses on both sides of the equation MUST be equal . This leads to all chemlcal reaction equations MUST be balanced , because each symbol no only represents an element but also represents a mass. ; Different elements have different masses. But overall the tota, ON BOTH sidesL must BE Equal. e.g. 20 g of A + 15 g of B = 30g of 'C' + 5g of 'D'. 20 + 15 = 30 + 5 = 35 Similarly 2NaOH + H2SO4 = Na2SO4 + 2H2O Notice there are 2 sodiums(Na) on both sides (2 x 23 = 46) 6 oxygens on both sides (6 x 16 = 96) 4 hydrogens on both sides ( 4 x 1 = 4) 1 sulphur on both ( 32 x 1 = 32). Since each element has its own atomic mass , the numbers of each element are the same on both sides, then it follows that the total masses are the samer on both sides. Hence the Law of CONSERVATION of MASS is obeyed. S
What side is the product side on a chemical equation?
The product side of a chemical equation is on the right side. It represents the substances that are formed during the reaction.
What is a very toxic chemical when welding?
Phosgene is a very toxic chemical that can be produced during welding when chlorinated hydrocarbon solvents come into contact with UV radiation from the welding arc. This can occur when cleaning metal surfaces with solvents containing chlorinated compounds before welding. Exposure to phosgene can lead to severe respiratory issues and even death.
What is the reactant(s) in the chemical equation below?
The reactants in a chemical equation are the substances that are present at the start of a reaction and are used up during the course of the reaction. If you provide the specific chemical equation, I can help you identify the reactant(s).
