What else can I help you with?
How do you mask the color given off in a flame test with the normal color of fire?
If you open the valve on the bunsen burner fully the flame becomes virtually invisible and therefore there are no interactions between the original flame colour and the colour produced by the chemical.
Energy flows from a Bunsen burner flame to the water because there there is a?
Energy flows from the Bunsen burner because heat is given off, creating a chemical reaction between the water and flame. This causes the water to heat up until the flame reaches 100 degrees and then the water boils (this is the waters boiling point).
What is the visible substance -given off by a burning object?
flame
What name is given to the region of burning gases?
a region of burning gases
Does the flame destroy the candle or just change its form?
The flame changes the form of the wax and the material of the wick into heat, light, and the carbon, and gases given off as smoke.
What chemical is given off in a burning flame?
The chemical given off in a burning flame is carbon dioxide (CO2) along with water vapor (H2O). Additionally, the color of the flame can be influenced by different chemicals present in the material being burned, such as sodium (yellow), copper (blue-green), or strontium (red).

How can you tell if a gas is being given off and what the procedure is called?
Elimination of a gas produce a specific noise. Some gases are tested with a flame or with chemical reagents impregnated on special paper.

What are practical application of flame test?
The flame test as a chemical test is rarely used as a diagnostic anymore. It has been replaced with ICP (Inductively Coupled Plasma) analysis that is basically a computerized flame test on steroids. ICP analysis allows researchers to quickly determine the elemental composition of almost any sample. One fun application of the flame test is fireworks. Fireworks are given their colors by the same chemicals that color flames in the flame test.
What is the visible substance -given off by a burning object?
flame
What are two MAIN forms of energy given off by a campfire?
Light and heat are the main forms of energy given off by a campfire. The light is produced by the flame as it burns the fuel, while the heat is a byproduct of the chemical reactions happening during combustion.
Heat is given off in the vincinity of the candle flame. this statement is an?
It is an Observation
What is the name given to the olympic flame bearer?
The Olympic torch bearer.
Is a candle burns chemical reaction?
Yes, burning a candle is a chemical reaction. The easiest way to tell if something is a chemical reaction is if heat or light are given of, a new substance is formed, or a colour change happens. Chemical changes are irreversible.Yes, whenever a candle burns, it is a combustion reaction between the carbon compounds of the wick and wax of the candle and of oxygen in the air. These compounds burn to create carbon dioxide and water, and also a few smaller carbon compounds, which is evident as the smoke rising occasionally from the flame. The flame you see and the heat you feel rising off of the burning wick is the evidence of an exothermic chemical reaction.Yes, burning a candle is a chemical reaction. The easiest way to tell if something is a chemical reaction is if heat or light are given of, a new substance is formed, or a colour change happens. Chemical changes are irreversible.
What general name is given to a laboratory chemical?
The general name given to a laboratory chemical is a REAGENT.
When sodium metal is added to water an orange flame is observed on the metal surface. Based on this observation what can best be concluded?
The observation of an orange flame when sodium metal is added to water indicates the release of energy in the form of light. This suggests that a chemical reaction is taking place between the sodium and water, likely producing sodium hydroxide and hydrogen gas.
