How does an explosion kill you?
Explosive shock waves can cause situations such as body displacement (i.e., people being thrown through the air), dismemberment, internal bleeding and ruptured eardrums.
Shock waves produced by explosive events have two distinct components, the positive and negative wave..
Why TNT is explosive?
TNT is explosive for two reasons: TNT is composed of the elements carbon, oxygen and nitrogen. When TNT explodes it forms several covalent gases: CO, CO2 and N2 that are very stable. The production of these very low energy (stable) bonds means that a great deal of energy is released.
What is formed if you mix two or more substances physically?
In chemistry, a mixture is a material made up of two or more different substances which are physically combined. A mixture is the physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions, suspensions and colloids.
What happens when two chemicals are mixed?
Tell students that sometimes when two (or more) substances are mixed together, a change occurs and another substance (or substances) is created. This is called a chemical reaction. Gas may form, heat may be produced, and color may change. These types of changes indicate that a chemical reaction has occurred.
What type of chemical reaction is an explosion?
An explosion consists of a series of reactions, highly exothermic, involving decomposition of the ingredients and recombination to form the products of explosion. Energy changes in explosive reactions are calculated either from known chemical laws or by analysis of the products.
How many apple seeds will kill a human?
200About 200 grinded apple seeds, which means around a cup of it, can be fatal for the human body. Cyanide can damage your heart and brain. It can even lead to coma and death in rare cases.
What is the poison that smells like almonds?
CyanideCyanide sometimes is described as having a “bitter almond” smell, but it does not always give off an odor, and not everyone can detect this odor. Cyanide is also known by the military designations AC (for hydrogen cyanide) and CK (for cyanogen chloride).
Which is the most dangerous metal?
Toxic MetalsArsenic. Common sources of exposure to higher-than-average levels of arsenic include near or in hazardous waste sites and areas with high levels naturally occurring in soil, rocks, and water. … Beryllium. Elemental beryllium has a wide variety of applications. … Cadmium. … Hexavalent Chromium. … Lead. … Mercury.

What elements can kill you?
So here is a list of substances that are more poisonous than their LD50 values might indicate.Botulinum toxins. Even though some of them are used in the cosmetic industry (including in botox), the botulinum family of neurotoxins includes the most toxic substances known to man. … Snake toxins. … Arsenic. … Polonium-210. … Mercury.
Are new substances formed in a mixture?
Which is which? A mixture is created when two or more different substances are physically combined and can be separated back into its original substances. A chemical reaction occurs when two or more substances are combined to form a new substance and cannot be separated back into its original substances.
What gas kills you instantly?
Carbon monoxideCarbon monoxide, or “CO,” is an odorless, colorless gas that can kill you.
What is the most explosive chemical?
Azidoazide azideAzidoazide 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.
What is the rarest element?
element astatineA team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element astatine, the rarest naturally occurring element on Earth.
What element is toxic to humans?
Trace elements that are most often associated with environmental toxicity are the heavy metals cadmium, chromium, cobalt, copper, iron, lead, mercury, nickel, silver, tin, and zinc, as well as the lighter elements aluminum, arsenic, and selenium. Some cases of elemental pollution are natural in origin.
What chemicals should not be mixed?
Dangers of Mixing Household Chemical CleanersBleach + Vinegar = Chlorine gas. This can lead to coughing, breathing problems, burning and watery eyes. … Bleach + Ammonia = Chloramine. This can cause shortness of breath and chest pain.Bleach + Rubbing alcohol = Chloroform. Another highly toxic combination!!Hydrogen peroxide + Vinegar = peracetic/ peroxyacetic acid.
What is the most deadly poison on earth?
Botulinum toxinBotulinum toxin Scientists differ about the relative toxicities of substances, but they seem to agree that botulinum toxin, produced by anaerobic bacteria, is the most toxic substance known. Its LD50 is tiny – at most 1 nanogram per kilogram can kill a human.
