1.Edmond Fouch is credited with the successful compression of acetylene and ?
2.What was Eugene Bournonville credited with the 1st commercial use of in 1970?
3.Sir edmund davy is credited with discovering what in 1836?

Answer 1

give me a moment...
1.
2. Something with welding-Eugene Bournonville, the man who brought oxyacetylene welding to American shores. Bournonville's engine didn't have staying power—the new Mazda RX-8 sports a Wankel engine—but his welding torch is still used today.
3. Acetylene
In 1836, Edmund Davy discovered a gas which he recognised as "a new carburet of hydrogen." It was an accidental discovery while attempting to isolate potassium metal. By heating potassium carbonate with carbon at very high temperatures, he produced a residue of what is now known as potassium carbide, (K2C2), which reacted with water to release the new gas. (A similar reaction between calcium carbide and water was subsequently widely used for the manufacture of acetylene.)

Thereafter it was forgotten until Marcellin Berthelot rediscovered this hydrocarbon compound in 1860, for which he coined the name "acetylene."
