A chemical reaction is a simple rearrangement of atoms leading to formation of newer substances(products). Hence, to favour the rearrangement,breaking of bonds in the reactants and making of bonds between atoms in the products occur.
Due to this in every chemical reaction there is involvement of energy (liberation or absorption depending on the bond energies of the elements in the reactant and the products). The energy involved may be light, heat or electrical energy.
All combustions (burning) are chemical reactions of a fuel with oxygen in which carbon-hydrogen and oxygen-oxygen bonds are broken in the reactants (except hydrogen) and carbon-oxygen and hydrogen-oxygen bonds are formed in the formation of the products.
The bond energies of these atoms are in such a way that the energy liberated is always more than the energy consumed for the breaking of bonds. The net energy is liberated in the form of both light and heat.

Does beryllium give a red flame test?
Its like Mg, it has no colour. So bright light
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.
How do you heat a test tube with a Bunsen burner?
the advantage of a blue flame is that it is more effecient(hotter flame less flue). the flame is hotter than a yellow one and no soot is produced which blackens test tubes
How can you test strontium nitrate ammonium carbonate and potassium sulfate?
A flame test.
Why cant flame test be use to identify non metals?
Non metals cannot emit a colored light.
Does beryllium give a red flame test?
Its like Mg, it has no colour. So bright light
What does it mean if no color is produced in a flame test?
The elements contained in this molecule are not able to give a color in the flame.
What color is the flame test for nickel?
Light green
What is the flame test for aluminum?
Aluminium ions like Magnesium ions have no colour in a flame test
What type of test can be used to identify calcium carbonate?
add hcl bubbles of co2 produced and flame test
What does Lithium carbonate look like in a flame test?
need to find the answer to what doe slithium carbonate look like in a flame test
Conclusion in flame test?
During a flame test, elements are heated, and their, electrons of the atoms gain energy from the flame. When they lose this energy, they emit colors of visible light. Since each element has its own specific light, you can easily identify which element has been heated
What is the flame test used for?
To indentify an unknown sample by its emission light
Why does magnesium not produce a color in the flame test?
it does not produce a flame colour because magnesium's colour is not in the visible light spectrum therefore we can not see the colour
Why sodium give a flame test?
Its electrons are excited to a higher energy state in the flame, and then they immediately release that energy, which is visible as yellow light.
What element is responsible for the green flame produced in the beilstein test?
The Beilstein test is a simple chemical test used to test for halides. A positive test result is indicated by a green flame which is caused by the formation of a copper halide. This test is not used often because of the possibility of generating highly toxic chloro-dioxins if the test material is a polychloroarene.
Is a flame test a qualitative or quantitative test?
The flame test in analytical chemistry is only qualitative.
