What is the name of the flame in Bunsen burners when the air hole is half opn?
The flame in a Bunsen burner with the air hole half open is called a yellow, luminous flame. This type of flame is inefficient as it produces soot and is cooler compared to a blue flame. Adjusting the air hole helps control the type of flame produced by the Bunsen burner.

Yellow slack flame is a cool flame Pale blue roaring flame is a much hotter flame. It was invented by the German Chemist , Robert Bunsen. Prior to which objects to be heated had to be put on an open fire, with no temperature control. The Bunsen Burner, whilst still used in the lab, has largely been superceeded by steam and electric mantles, where the temperature can be more closely controlled, together with the fact that mantles are safer pieces of lab. kit.
When doing Bunsen burners which flame do you use the most?
The flame that you use the most is the safety flame. The safety flame is the yellow one it is not too hot and not too cold. The air hole should be half open for the safety flame and it makes a hissing sound. Your Welcome xx :D

What is used in science for heating?
Bunsen Burner Bunsen burners are typically used to heat beakers of liquid in order to induce chemical reactions. Bunsen burners also pose disadvantages: They cannot control the temperature as accurately as electronic heaters and using an open flame can be dangerous.
What colour is the flame when the airport is open and when the airport is closed on a Bunsen Burner?

Is a Bunsen flame hottest when the hole is open or close?
A Bunsen flame is hottest when the air hole is open. When the air hole is open, more oxygen can mix with the gas, resulting in a hotter and more efficient flame. Closing the air hole restricts the amount of oxygen, leading to a cooler flame.

Color of flame in a complete combustion of gas from Bunsen burner?
When the air hole is covered on the Bunsen Burner its oxygen supply is made smaller. This makes the flame turn YELLOW - This is considered to be the safety flame as it is the most visible to the eye and it radiates less heat. When the Bunsen burners air hole is fully open there is a super heated blue flame which is the product of complete combustion. Hope this helped :)
What safety rules apply when using Bunsen burners in the lab?
- don't work with flammable, explosive, very toxic or radioactive chemicals - work in a fume hood - use protective glasses - survey permanently the flame of the burner - do not let the flame open when you go home
