Fire: The Molotov cocktail A Molotov Cocktail is defined as a crude bomb made of a bottle filled with a flammable liquid and usually fitted with a wick that is ignited just before the bottle is hurled (Merriam-Webster Dictionary). The Molotov cocktail is an improvised incendiary explosive device crafted out of easily attainable ingredients. Due to it’s relatively ease of production they are often found in the hands of violent protesters and/or poorly equipped and non-profession guerilla combatants. The main purpose of the Molotov is to light the target ablaze rather than instantly killing it. Although it is a lethal weapon, the objective of the Molotov is to inflict damage all while leaving the target stunned in a way.
The products of a combustion reaction are carbon dioxide and water. I also found out that it takes skill to light a match and that it’s difficult to keep gas where you want it to be without a sealed container. There are many sources of error. The first source of error was that if you blow on the candle too hard, the wax vapor blows away and the flame doesn’t jump. The next source of error is that if you don’t put in the limewater and stopper quickly enough, the carbon dioxide escapes and the water won’t turn chalky.
The relatively high oxidising power of the halogens could be due to their electronic configuration. All the halogens are in the p sub shell. The P sub shell contains the highest energy electrons, so this is also another factor due to their high oxidising power. As you go down the group the elements become less volatile. Fluorine is a yellowish green gas at room temperature, Chlorine is Greenish yellow gas, Bromine is a dark red liquid that is volatile and give off a dark red-brown vapour , and iodine is a shiny grey solid.
There is also the element of nuclear "residue" from the nuclear blast. Radioactive contaminants will be found on the ground and in the air. And the airborne ones will circulate causing the radioactive materials to be deposited many miles from ground zero. This ends up creating health damaging effects far from the site of the blast, making the atomic bomb far more deadlier than the napalm
The procedure of making the explosive substance was very dangerous, one spark could have resulted in a smoky fire. So, to reduce the danger of an accident, liquid was added to the mixture. It was then made into small pellets and dried. The deadliest weapons, gunpowder, the gun and the rifle were strangely invented during the quest for immortality. This marked one of the most important steps for gunpowder,
(As you can guess, different fuels begin burning at different temperatures.) Heat or ignition sources lift fuel (combustible material) to its activation energy to start the fire. The fire generates heat which sustains the chemical reaction; the blaze continues and spreads. Some firefighting tactics shield the fuel from air (oxygen) to extinguish the blaze. Carbon dioxide fire extinguishers expel a cold fog of CO2 that cuts a fire off from its air supply.
It is produced by reacting nitric acid and sulphuric acid simultaneously. The lone pair from oxygen breaks the OH bond when it comes in contact with sulphuric acid. Furthermore, NO2OH2 break and dissociate to form H2O water along with the electrophiles NO2. The electrons from the benzene ring attack NO2 causing the double bond to break. Multiple resonance is created from the movement of electrons.
Because of limitless industrial importance of PUs, hence need to study diisocyanate chemistry briefly and understand the properties and their reactivity. Mainly the isocynates are highly reactive and allow to forming urethane groups without any by-products formation. This isocyanates contains two or more –NCO functional groups for one molecule is called as diisocyanes or polyisocyanate respectively. The industrial important monoisocyanate compound is methyl isocyanate (MIC), majorly used to manufacturing of pesticides but this isocyanate is extremely hazardous which is responsible to Bhopal disaster, in 1984. All diisocyanate are liquids or solids in the nature and highly reactive, it undergo reaction across the double bond C=N of the –NCO group.
Finally, the nuclear electromagnetic pulse is made of extremely strong magnetic fields. This pulse disturbs the radio contacts and destroys and electronic devices (“The Atom Bomb – the development of the atomic bomb, the uses of the atomic bomb”). So what all happened to Japan when the first two atomic bombs
The more explosive a volcano, the more hazardous it usually is. The type of magma is a huge physical factor determining the volcanoes level of explosiveness, based on the temperature, gas content and chemical components volcanologists can tell how viscous the magma is. The higher the temperature of the magma and lower the silica content the runnier it will be and therefore less explosive however, a lower temperature and higher gas content would cause a more explosive eruption as the gas wouldn’t be able to escape due to the density of the magma, high silica content would also cause more internal friction and increase explosivity. These types of eruptions are common with rhyolite rock type within the magma. However, viscous lavas are not always the most hazardous; an example of a low viscosity, destructive eruption is that of Mt.
