<span>Iodine, I2, reacts with fluorine, F2, at room temperature to form the pentafluoride iodine(V) fluoride.
At 250°C the same reaction forms the heptafluoride iodine(VII) fluoride. With careful control of the reaction conditions, (-45°C, suspension in CFCl3), it is posible to isolate the trifluoride iodine(III) fluoride.
I2(s) + 5F2(g) → 2IF5(l) [colourless]
I2(g) + 7F2(g) → 2IF7(g) [colourless]
I2(s) + 3F2(g) → 2IF3(s) [yellow]</span>

Answer:
yes, the trash did disappear when she burned it however it releases smoke into the air (and harmful chemicals)
Explanation:
burning trash doesn’t only allow the waste to go down, it will also produce heat and electricity-while producing less greenhouse gas pollution than burning fossil fuels. However trash fires in burning barrels can smolder and, as a result, produce more harmful chemicals in smoke. Harmful contaminants can also be found in dirt. in conclusion, yes trash does disappear when burned but realeases many harmful chemicals.
hope this helped!
Answer:
Waves have many properties, including frequency, wavelength, amplitude, timbre, and direction.A higher frequency sound is perceived as a higher note, because frequency is the same thing as pitch. The amplitude is how tall the wave is. A higher amplitude sound wave is a louder sound.
