I once heard that the powder on the ignition strip in the matchbox is phosphorus and that the substance burns at extreme heat, but does the powder on the tips of the matches burn just as hot?

Loading...I have been given a question that I cannot fully understand, since the first main group is very reactive. Task: Explain why ions of the elements of the first main group (e.g. Na or Na') are less reactive than atoms of the uncharged, elemental form
Hey, This year I'm participating in the IChO (International Chemistry Olympiad) for the first time. As the deadline approaches, I'm wondering if you have any recommendations on how I should best submit my answers. For background, the tasks require not only written answers, but also drawing structural formulas and completing crossword puzzles. Thanks in advance
Hello everyone I have a question regarding the acid base reaction. According to Arrhenius, an acid + a base should produce a salt and a water. I have an example in my learning materials which reads as follows. Example: H3PO4+NH3 The reaction equation should (I think) be as follows. H3PO4+NH3=>NH4(+)+H2PO4(-) Now I'm wondering why there's…
Hello, I urgently need help. Does anyone know anything about this? What mass in µg of Cr3+ ions is present in 84.295 L of a saturated solution of chromium(III) hydroxide? Note: KL = 6.7 · 10-31. The result should be given with one decimal place
Hey everyone, I have a question: Does anyone have an example of the last three? A picture of what they look like and a connection to them would be enough for me. The main thing is to see examples. Thanks in advance.
Hello folks, I would be very grateful if someone could explain steps 4 and 5 of the electron pair bond to me. (We don't need to know the circled part, the one with infinity.) Thanks in advance!
A mixture of potassium chlorate, sulfur, glue and usually glass powder is present on the plywood head, which prevents sparks or hot slag from being sprayed.
On the friction surface there is red phosphorus which, with the potassium chlorate in the plywood head, forms a type of amstrong mixture (impact-sensitive explosive) which can be ignited by the friction.
Red phosphorus alone, in my knowledge, does not burn extremely hot or good. However, it looks different at the plywood head.

Didn’t even know that the rough stripe is combustible.
