How can the chemical reaction of vinegar and baking soda make a flame go out?
The chemical reaction of vinegar and baking soda produces carbon dioxide. Carbon dioxide, which is heavier than oxygen, smothers a flame starving it of the oxygen it needs to burn.
Is a yellow flame of a Bunsen burner hotter than the blue flame?
No, a blue flame of a Bunsen burner is hotter than a yellow flame. The blue flame indicates complete combustion of the gas, which produces a higher temperature compared to the yellow flame's incomplete combustion.
Is burning newspaper a physical change?
Yes, burning newspaper is a chemical change because it undergoes a chemical reaction (combustion) that changes its chemical composition. The heat and flame produced during burning are evidence of this chemical reaction taking place.
How do you get blue flame to yellow flame?
To change a blue flame to a yellow flame, you can adjust the air mixture going into the gas burner. Increasing the amount of air mixed with the gas will result in a yellow flame. This can usually be done by adjusting the air shutter on the burner.
Is the inner part of a luminous flame yellow?
Yes, the inner part of a luminous flame is typically yellow. The yellow color is due to the incomplete combustion of carbon particles present in the flame.
What is the lowest temperature flame that can be produced by a chemical reaction?
The lowest temperature flame that can be produced by a chemical reaction is around 600 degrees Celsius.
In the reaction of sodium with oxygen?
When sodium reacts with oxygen, sodium oxide is formed. The reaction is highly exothermic and produces a bright yellow flame. The chemical equation for the reaction is: 4Na + O2 -> 2Na2O.
What chemical reaction produces a flame?
A combustion reaction is a chemical reaction that produces a flame when a fuel (such as a hydrocarbon) reacts with oxygen (from the air) to produce heat and light. This process releases energy in the form of heat and light, resulting in the flame that we see.
How do cars run on chemical reaction?
Your car runs on a chemical reaction because the combustion of gas is actually a chemical reaction. As the fuel turns to a spark or flame, the reaction becomes chemical
How does luminous flame exist?
A luminous flame is produced when a chemical reaction (such as combustion) releases energy in the form of light. The presence of solid particles or molecules in the flame can also contribute to its luminosity by emitting light as they are heated. This is different from a non-luminous flame, which does not produce visible light.
If the colour of a flame changes from blue to yellow after inserting a wire dipped in chemicals is this a physical or chemical change?
Both, But The Heat chemically alters the molecules of the chemical on the wire (and the wire as well), changing the color (actually the color is the same. its more accurate to say the new color is added by the burning of the chemical. Technically its not a physical reaction since this experiment doesn't leave the two components in the same state they were in before the reaction. However they is a lot of physical reaction going on with the flame rising, etc.
How can the chemical reaction of vinegar and baking soda make a flame go out?
The chemical reaction of vinegar and baking soda produces carbon dioxide. Carbon dioxide, which is heavier than oxygen, smothers a flame starving it of the oxygen it needs to burn.
What type of reaction is taking place when Butane burns to produce a flame?
The combustion of butane to produce a flame is a chemical reaction known as a combustion reaction. In this reaction, butane reacts with oxygen to produce carbon dioxide, water, and heat energy.
Is yellow solid physical or chemical property?
physical (because you can observe it without inducing a chemical reaction).
Chemical reaction between man and flame?
Burns. Very severe burns. It's easy if you think about it.
Is a flame a source of light?
The flame of a candle is a source of light.
Is flame a example of physical change or a chemical change?
Something burning is a chemical change because it is combining with the oxygen in the air. Ex. when you burn sugar you get c02 and water, the reason the water doesnt put out the fire is that the water is released as a gas.
