Is reactivity A extensive or intensive property?
Is reactivity A extensive or intensive property?
Intensive properties are used to identify a substance and do not depend upon the amount of substance (density). Extensive properties depend on the quantity of the substance (mass, volume). Chemical matter properties include flammability and reactivity.
Is chlorine a reactivity?
Halogens are notorious electron-hogs; powerfully attracting electrons from atoms of other elements, particularly from the alkali metals. This makes the halogens highly reactive. Chlorine, being one of the smaller halogens, will react strongly with most elements.
What is the properties of chlorine?
Chemical properties of chlorine – Health effects of chlorine – Environmental effects of chlorine
| Atomic number | 17 |

Is chlorine inert or reactive?
Chlorine is a yellow-green gas at room temperature. It is an extremely reactive element and a strong oxidising agent: among the elements, it has the highest electron affinity and the third-highest electronegativity on the Pauling scale, behind only oxygen and fluorine.
Is reactivity with water an intensive property?
Intensive properties do not depend on the amount of substance. For example water boils at the same temperature no matter how much water you have. Likewise, melting point is also an intensive property. Other examples of intensive properties include density , solubility, color, luster, freezing point and malleability.
Why is chlorine very reactive?
Chlorine atoms have a lot of valance electrons without being complete on its own, so it has a greater need to seek it’s conjugates. That’s called Electronegativity. Halogens are highly reactive because of their electronegativity.
Is cl2 a chlorine?
At standard temperature and pressure, two chlorine atoms form the diatomic molecule Cl2. Along with fluorine, bromine, iodine and astatine, chlorine is a member of the halogen series that forms the group 17 of the periodic table – the most reactive group of elements.
What are 5 physical properties of chlorine?
Properties: Chlorine has a melting point of -100.98°C, boiling point of -34.6°C, density of 3.214 g/l, specific gravity of 1.56 (-33.6°C), with a valence of 1, 3, 5, or 7. Chlorine is a member of the halogen group of elements and directly combines with almost all of the other elements.
Is chlorine 36 stable?
Chlorine has two stable isotopes and one cosmogenic isotope. The cosmogenic isotope, 36Cl, has a long half-life, making it useful in age dating groundwaters up to 1 million years old. There is also limited variation in 37Cl. Most natural variation in 37Cl values in hydrologic systems are related to diffusion processes.
Why is solubility an intensive property?
An intensive property is a property of matter that depends only on the type of matter in a sample and not on the amount. Color, temperature, and solubility are examples of intensive properties.
What are the physical and chemical properties of chlorine?
Chemical Properties 1 General. Chlorine has a characteristic penetrating and irritating odor. 2 Atomic and Molecular Properties. Atomic Weight – 35.453 Molecular Weight of Cl 2 – 70.906. 3 Chemical Properties. The mass of a unit volume of chlorine at specified conditions… 4 Flammability. Chlorine is neither explosive nor flammable.
What are some intensive properties?
Intensive Properties. Intensive properties are bulk properties, which means they do not depend on the amount of matter that is present. Examples of intensive properties include: Boiling point. Density. State of matter. Color. Melting point.
How does chlorine react with other organic compounds?
Chemical Reactions. Reactions with Organic Compounds Chlorine reacts with many organic compounds to form chlorinated derivatives. Some reactions can be extremely violent, especially those with hydrocarbons, alcohols and ethers. Proper methods must be followed, whether in laboratory or plant, when organic materials are reacted with chlorine.
What are the reactions of chlorine with metals?
Chemical Reactions. However the resulting water phase is extremely corrosive, see Reactions with Metals below. Reactions with Metals The reaction rate of dry chlorine with most metals increases rapidly above a temperature which is characteristic for the metal. Two of the more common metals are titanium and steel.
