Which reaction is exothermic and produces a purple smoke?
When potassium chlorate and ordinary table sugar are combined, and a drop of sulfuric acid is added as a catalyst, the two react violently with each other, releasing large quantities of heat energy, a spectacular purplish flame, and a great deal of smoke.
Why is ni3 explosive?
The reason nitrogen triiodide is so unstable is down to its molecular structure – one nitrogen atom and three iodine molecules all on one side due to how the nitrogen’s electrons are arranged. And all that repelling causes something called bond strain, which makes the entire molecule extremely unstable.

What’s the most explosive substance?
Azidoazide azide is the most explosive chemical compound ever created. It is part of a class of chemicals known as high-nitrogen energetic materials, and it gets its “bang” from the 14 nitrogen atoms that compose it in a loosely bound state. This material is both highly reactive and highly explosive.
Where can I buy iodine crystals?
Crystals typically are available for sale at chemical supply stores, feed and tack stores, and veterinary clinics and suppliers. Iodine also is widely available on the Internet. One online pharmacy, for example, sells iodine crystals in ounce quantities for approximately $14.
How do you make solid nitric iodine?
One method is to simply pour up to a gram of iodine crystals into a a small volume of concentrated aqueous ammonia, allow the contents to sit for 5 minutes, then pour the liquid over a filter paper to collect the NI3, which will be a dark brown/black solid.
What colour is fluorine?
pale yellow

How are colored smokes made?
Here are some formulations for colored smokes. The parts or percents are by weight. Basically what you do is measure the ingredients, sift them together to mix them, and ignite the powder to produce smoke. Up to 2% sodium bicarbonate (baking soda) may be added to slow the combustion/cool the reaction, if necessary.
How big do purple smoke plants get?

What does the color of the smoke indicate about the fire?
Smoke Color Can Depict Fuel Type. Smoke is the biproduct of the fuels it is burning.
