Why does KCl potassium chloride make high energy purple flames and SrCl2 strontium chloride makes low energy red flames?

potassium and strontium both absorb heat energy and this makes electrons(e-) jumpfrom the base (normal) energy level to a higher energy level. The base is NOT etactly the same for these 2 elements and neither are the higher levels. This transition absorbs different amounts of energy. This absorbed energy is released as various electromagnetic waves when the e- transition back to the lower (base) energy levels. Different amount or energy are released which correlates to different colors of the electromagnetic spectrum.

Two of this elements compounds burn with a red flame and are used in fireworks and signal flares?
Lithium, strontium and calcium have red flames.
What salts produce lilac flames?
Salts containing potassium.
What are 4 What are facts about strontium?
1) Strontium bursts into flames when it is exposed to air. 2) It was discovered in Scotland. 3) It's used in fireworks and toothpaste. 4) Strontium is a soft, silvery metal. 5) Strontium titanate is very soft but has an extremely high refractive index and an optical dispersion greater than that of diamond. (It bends and separates light)
Why are flames orange?
Flames aren't always orange, their colour is depenant on what material is being burned. A substance with contains a high percentage of copper will burn with a green flame and if is contains strontium the flame would be red. Different substances produce different flame colours and this property can be used to identify substances. Orange flames indicate the presence of Sodium.
What compounds create red and purple fireworks?
The addition and combination of various powdered metals and minerals added in various combinations produce the colors that we see. Copper, magnesium, iron powders, sulphurs , and many other elements all combine to create the palette of colors pyrotechnical artist's employ for our pleasure. Copper is used to make the blue colour of fireworks. Although copper produces a green flame in a laboratory flame test, the use of copper in relatively low temperature flames and in the presence of chlorine produces CuCl+ ions that give out bright blue emission lines at moderately flame temperatures. Caesium can also be used, but this is much too expensive for normal use. In general, the difficulty of producing blue flames in fireworks means that their presence in a firework display is is a reasonable indicator of the expense and quality of the display. magnesium gives a brilliant white light. Copper, although rare because of the dangers of reacting with potassium chlorate to produce highly explosive copper sulfate, can be burned to produce a brilliant blue light.

When placed into water it bursts into flames?
potassium
Why does potassium produce a flame when reacted with water?
Because the reaction is highly exothermic. when potassium touches water the substances react chemically and the bonds created, thereby releasing a lot of energy. This energy can ignite the hydrogen gas produced to create flames.
What salts produce lilac flames?
Salts containing potassium.
Does a candle have thermal energy?
A candle has thermal energy because of it flames, the flames have heat and thermal energy is heat.
Why do yule logs burn red and green?
Some Yule logs that are available commercially have green and red flames when they burn. The chemicals that cause the colored flames are barium and strontium.
What color flames do you get when you burn the elements?
Manganese (II) Chloride - pale yellow-green strontium chloride - red sodium chloride - bright yellow-orange lithium chloride - red copper (II) chloride - bright green calcium chloride - yellow-red boric acid - nothing
What two of this elements compound burn with a red flame and are used in fireworks and signal flares?
Lithium, strontium and calcium have red flames.
Does flames occur in a chemical reaction?
Flames can occur during chemical reactions that release considerable energy, if other conditions are favorable. For example, it is widely reported that if metallic potassium is dropped into water in a container open to the atmosphere, the release of energy is so high and the release of hydrogen so rapid that the hydrogen bursts into flame. More prosaically, kerosene and similar materials can be burned from a wick to produce continuous light from better controlled flames.
How can you identify an unknown using a flame test?
The emission spectrum of the element is compared with known spectra.

What is strontium in?
Strontium occurs naturally in the minerals celestite and strontianite. The 90Sr isotope is present in radioactive fallout and has a half-life of 28.90 years. Due to its extreme reactivity to air, this element occurs naturally only in compounds with other elements, as in the minerals strontianite, celestite, etc. Strontium is isolated as a yellowish metal and is somewhat malleable. Strontium is chiefly employed (as in the nitrate) to color pyrotechnic flames red.
