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 kinds of energy is given out by a firework?
A flame releases thermal energy - heat - to the surroundings via conduction to the surrounding air, convection of the air thus heated, and radiation due to the difference in temperature between the flame and the surrounding area. It also releases energy in the form of light.
What name is given to the region of burning gases?
a region of burning gases

What chemical is given off in a burning flame?
The principal components are carbon dioxide, water, carbon monoxide, sulfur dioxide, soot.

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?
A chemical reaction occurs because heat and light are given off.
Is carbon given off by a burning candle?
If the flame is allowed to cool before complete combustion, then carbon black may be formed. Made by different methods, this is an important industrial chemical.
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
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.
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.
