Is sodium easily burn with a small flame in air?
The sodium is alkali metal it cannot be easily burn in a small flame
How do you obtain blue flame on burn-sen burner?
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.
What is the function of the air jet?
to feed oxygen to the flame allowing it to burn
What gas in the air is needed for something to burn?
Oxygen is needed to feed the flame.
Does a fossil fuel burn in the air?
All fuels that 'burn' require air or an oxygen source for combustion. Therefore,fossil fuel also burn in the air.
Does the blue flame on a Bunsen burner need the air hole open or shut?
It needs to be open to create the hot, blue flame that roars. If the air hole is shut, the flame will burn yellow, similar to a candle.
How does a candle burn in the air?
A candle is able to burn in the air due to the presence of oxygen. The wick of the candle (usually made up of braided cotton) "draws" the wax up to the flame, providing the flame with combustible material to continue burning.
How does wax burn?
Heat from the flame melts the wax. The molten wax is drawn up the wick by capillary action. Heat from the flame vaporizes the molten wax in the wick as the wax enters the flame. The hot wax vapors burn as they mix with air.
Explain why opening the air hole of a Bunsen burner makes the flame hotter.?
Because more air is able to fuel the flame's reaction; the collar at the bottom of the tube is adjusted so more air can mix with the gas before combustion, the flame will burn hotter.
Why are some material burn with flamewhile other without flame?
Some elements react fiercly with oxygen in the air while others require the heat from a flame to induce a reaction. For example, magnesium ribbon needs to be heated to react with oxygen. But pure sodium will react with oxygen in the air quickly and therefore needs to be stored in oil.
What does a flame need to burn?
For a flame to burn it needs fuel, oxygen, and heat.
Why does a bonfire burn more when there is a draft?
I think it is caused by the air causing the flame to keep eating at whatever is combustible. Like blowing on a wick to cause the flame to grow.
