Why is it important to light the match before opening the gas tap when lighting a Bunsen burner?
It is important to light the match before opening the gas tap when lighting a Bunsen burner to prevent gas from escaping and potentially causing an explosion. Lighting the match first ensures that the flame is present to ignite the gas as it is released.
What gas is it that we need to stay alive. it is also needed for burning.a burning splint will burn brightly in this gas?
Oxygen is the gas that we need to stay alive and is also required for burning. A burning splint will burn brightly in oxygen because it supports combustion.
Why does the gas have to be turned one after the match is lit?
If you begin the flow of gas on a range prior to lighting the match, the gas will accumulate in the air and could potentially cause an explosion. If the match is lit and placed near the source of gas-flow prior to release, when the gas is released it will immediately and properly ignite.
Why splint burns steadily in air and flares up when put in a gas jar?
beacuse oxygen support combustion and outside the jar air is present which is a mixture of gases in which nitrogen is 78%,oxygen is 21% and remaining 1% are He,Ne,Ar,xe,Kr,CO2 and other gases.This is the reason why a glowing flares up in a gas jar of oxygen but not in air
Why does a lighted match stick put out when brought near a jar containing hydrogen?
A match won't light in hydrogen. It needs some oxygen.If you light a match in a mixture of hydrogen and oxygen, you'll ignite the hydrogen ...which also wants very much to burn in oxygen. The hydrogen will combine (burn) withthe oxygen instantly, brightly, and possibly loudly. The product that remains after thehydrogen finishes burning is H2O .
How do you tell if there is gas in your oil?
Pull the dipstick and see if the oil on it flares up quickly when you heat it with a match.
What is one way to determine the presence of oxygen gas?
If the gas will sustain a flame of a match, oxygen is present.
Why do we light a match first before turning on the gas for the Bunsen burner?
We light a match first before turning on the gas for the Bunsen burner to prevent the gas from flowing out and potentially causing a buildup of gas without ignition. Lighting the match first ensures that the flame is present to ignite the gas as soon as it is released.
What gas is found in brightly colored lights?
Neon
What are violent explosions from sunspots in which gas and tremendous amounts of energy are blasted into space away from the Sun?
They are known as solar flares.

It is important to light the match before opening the gas tap when lighting a Bunsen burner to prevent gas from escaping and potentially causing an explosion. Lighting the match first ensures that the flame is present to ignite the gas as it is released.
What is it called when gas shoots out of the sun?
These are solar flares or coronal mass ejections(CMEs).
What gas is it that we need to stay alive. it is also needed for burning.a burning splint will burn brightly in this gas?
Oxygen is the gas that we need to stay alive and is also required for burning. A burning splint will burn brightly in oxygen because it supports combustion.
What is a ball of hot gas that astronomers study and burn brightly in the atmosphere?
The sun
What are blasts of gas from the sun's atmosphere that sometimes forms enormous loops?
Solar flares are blasts of gas from the sun's atmosphere that can form enormous loops due to the sun's magnetic field. These loops are known as coronal loops and can span many times the diameter of the Earth. Solar flares can release massive amounts of energy and particles into space.
Why doesn't the gasoline in a car's gas tank explode when the gas cap is removed?
Because there is no spark or flame present. If the tank is full it wont even explode if you throw a match in it, However if the tank has a large area that has no liquid fuel in it then the addition of a lit match or spark will cause it to explode.
What is the best way to remove gas from a vehicles gas tank?
with a match put match inside tank. burn it out.
