activity series reactions

This series is an important tool that helps in predicting many electrochemical reactions. All metals placed above hydrogen will displace hydrogen from acids while those below it do not displace hydrogen from acids. Elements with high electropositive or electronegative powe..

Take a nichrome wire of about 50 cm length and apply a potential difference of 1.5 V from a battery. Measure the current flowing through the wire using an ammeter connected to it in series, and note the potential difference across the resistance using a voltmeter connected across it. Note..

The importance of the above reactions lies in the production of nitric acid, which is a very important industrial produc..

Extracting Metals towards the Top of the Activity Series - Metals such as sodium, magnesium, calcium, aluminium high up in the reactivity series are very reactive and cannot be obtained from their compounds by heating with carbon. This is because these metals have more..

(formation of organometallic compounds) Haloalkanes react with other active metals such as lithium, zinc, mercury, lead, etc. in the presence of dry ether to form the corresponding organometallic compounds. For example, Tetraethyl lead (TEL) is used as an antiknocking agent in gasoli..

Extracting Metals Low in the Activity Series - Metals that are low in the activity series are very un-reactive. The oxides of these metals can be reduced to metals by heating alone. For example, mercury is obtained from its ore, cinnabar (HgS), by the process..

Metals that are low in the activity series are very un-reactive. The oxides of these metals can be reduced to metals by heating alone. For example, mercury is obtained from its ore, cinnabar (HgS), by the process of heating. Reduction Using Heat Copper can also be obt..

Example 11: The rate constants of reaction at 700 K and 760 K are 0.011M - 1 s - 1 and 0.105 M - 1 s - 1 respectively. What are the values of 'A' and 'E..

A complex reaction involving two series reactions can be of the type, ..

A complex reaction involving two series reactions can be of the type, A reacts to give B, which is then transformed to C. Both the elementary reactions (1) and (2) exhibit first - order kinetics, that is, For this reaction, [A] = [A] o exp (-k 1 t) ..
