What are the 3 major types of chemical reactions?
The more common types of chemical reactions are as follows: Combination.
What are three types of chemical reactions?
Types of Chemical ReactionsSynthesis reactions. Two or more reactants combine to make 1 new product. … Decomposition reactions. A single reactant breaks down to form 2 or more products. … Single-replacement reactions. A single element replaces a similar element of an adjacent reactant compound. … Double-replacement reactions. … Combustion reactions.
What is the antidote for sarin gas?
ANTIDOTE: Atropine and pralidoxime chloride (2-PAM Cl) are antidotes for nerve agent toxicity; however, 2-PAM Cl must be administered within minutes to a few hours (depending on the agent) following exposure to be effective. There is also generally no benefit in giving more than three injections of 2-PAM Cl.
What happens if I mix bleach and ammonia?
When bleach is mixed with ammonia, toxic gases called chloramines are produced. Exposure to chloramine gases can cause the following symptoms: Coughing. Nausea.
Which gas is very dangerous?
Among the best known toxic gases are carbon monoxide, chlorine, nitrogen dioxide and phosgene.
What is the most powerful chemical?
PETN. One of the most powerful explosive chemicals known to us is PETN, which contains nitro groups which are similar to that in TNT and the nitroglycerin in dynamite. But the presence of more of these nitro groups means it explodes with more power.
What is the most responsible for chemical reactions?
ElectronsElectrons are the smallest subatomic particle. They are responsible for much of the chemistry we “see.” Chemical reactions are a result of changes in bonding; in a chemical reaction, atoms switch out bonding partners. The desire to lose, gain, or share electrons is what drives bonding between atoms.
What cleaning supplies can kill you?
The household cleaners that you should never mix at the risk of creating toxic gassesBleach is especially toxic and should not be mixed with anything other than water.Some of the most deadly combinations are ammonia and bleach, vinegar and bleach, and rubbing alcohol and bleach.More items…•
What is the most poisonous gas on Earth?
Hydrogen sulphideOriginally Answered: What is the most poisonous gas in the world? Hydrogen sulphide reduces the body’s oxygen supply and in doing so, directly damages the cells of the nervous system and paralyzes the respiratory system. Very high concentrations of hydrogen sulphide can cause immediate coma or even sudden death.
Which gases can kill you?
All gases other than oxygen can displace air, and cause death by asphyxiation. This does not make them poison gases. Nitrogen and carbon dioxide are two common examples. This has to be taken into account in handling of any compressed or liquified gas.
Which are the most common chemical reactions in the body?
In human body the most common or you can say usual chemical reaction is respiration. Respiration is simply gaseous exchange, with release of energy. It can be stated as in oxidation reaction, where which oxygen from air get absorbed and mixed with food and then it produces energy.
How do you know if a reaction is reversible or not?
In a reversible reaction, both forward and reverse directions of the reaction generally occur at the same time. While reactants are reacting to produce products, products are reacting to produce reactants. Often, a point is reached at which forward and reverse directions of the reaction occur at the same rate.
What gas kills you instantly?
Carbon monoxideCarbon monoxide, or “CO,” is an odorless, colorless gas that can kill you.
What is the most deadly chemical?
Botulinum toxin1. Botulinum 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.
What would happen if you breathe pure oxygen?
Pure oxygen can be deadly. Our blood has evolved to capture the oxygen we breathe in and bind it safely to the transport molecule called haemoglobin. If you breathe air with a much higher than normal O2 concentration, the oxygen in the lungs overwhelms the blood’s ability to carry it away.
