Ideal Gas Law - HyperPhysics Concepts

Ideal Gas Law An ideal gas is defined as one in which all collisions between atoms or molecules are perfectly eleastic and in which there are no intermolecular attractive forces. One can visualize it as a collection of perfectly hard spheres which collide but which otherwise do not interact with each other.

Activity Series of Metals: Predicting Reactivity

28/2/2020· The activity series is a chart of metals listed in order of declining relative reactivity. The top metals are more reactive than the metals on the bottom. For example, both magnesium and zinc can react with hydrogen ions to displace H 2 from a solution by the reactions: Mg (s) + 2 H + (aq) → H 2 (g) + Mg 2+ (aq) Zn (s) + 2 H + (aq) → H 2 (g

Standard Gibbs free energy of formation - Wikipedia

The standard Gibbs free energy of formation (G f ) of a compound is the change of Gibbs free energy that accompanies the formation of 1 mole of a substance in its standard state from its constituent elements in their standard states (the most stable form of the element at 1 bar of pressure and the specified temperature, usually 298.15 K or 25 C).

Reaction of Aluminum with Water to Produce Hydrogen

In the vicinity of room temperature, the reaction between aluminum metal and water to form aluminum hydroxide and hydrogen is the following: 2Al + 6H 2 O = 2Al(OH) 3 + 3H 2. The gravimetric hydrogen capacity from this reaction is 3.7 wt.% and the volumetric

A Basic Overview of Fuel Cell Technology

Hydrogen is the basic fuel, but fuel cells also require oxygen. One great appeal of fuel cells is that they generate electricity with very little pollution–much of the hydrogen and oxygen used in generating electricity ultimately coine to form a harmless byproduct, namely water.
