The products contain more energy than the reactants.
with fire and some paper goes out easily, those you can't really catch on fire it will just go out
You write "fire" on the paper.
Metals conductThe coin is made of metal or a metal alloy. Metals are excellent conductors of heat and electricity. When you place the paper and coin directly over the flame, the coin conducts heat away from the paper. If the coin conducts heat away from the paper at least as fast as the flame adds thermal energy to the paper, it will not reach its flash point and will fail to ignite. It may not even scorch. If the coin, however, cannot dissipate the heat to the surrounding air and itself heats up, it will no longer act as an efficient conductor, and the paper will eventually burn.Though not nearly as much, I imagine it also has some to do with the slight lack of oxygen that is available with the coin over the paper.
It can't burn you, it's a safety flame. The blue flame is the real hazard. It is 1800 degrees so do not touch it. Apart from that there is nothing to worry about. P.S. Don't forget to wear safety goggles when doing any chemistry or heating! I hope I helped :)
Increase the air flow by opening the circular valve on the stem of the burner. This will cause the flame to burn more intensely and with a blue flame. When the valve is closed, the flame will burn yellow and cooler - more like a wax candle's flame.
When you put lemon juice on a piece of paper, then place the paper on a heat source, the parts soaked with the juice will burn faster and turn a dark brown. This chemical reaction is based upon the properties that define acids and bases. The paper with the acid lemon juice is weakened by the acid, and will burn faster.
The sodium is alkali metal it cannot be easily burn in a small flame
we would the cup and the paper burn like when you put news paper on a bbq.
the gas from the Bunsen burner will cause the existing flame to flare and burn the entire piece of paper and your fingers - and the lab. it's difficult to blow out the burning paper.
with a lighter
Just burn it!
Water. But not indefinitely.
yes only if you touch right after the flame goes out

Real money burns bright Orange...Counterfeit bills burn a Blue color
For a flame to burn it needs fuel, oxygen, and heat.
Paper did burn in the towers, but the impact of the planes destroyed many windows and also caused it to fly out. Most of the initial flame, based on research, shot down the elevator shafts.
The homophone that means to burn with sudden flame is "flair" - this refers to a sudden burst or flare of fire or light.
