How would increasing the pressure of a system will have what effect on the equilibrium of this reversible reaction 3H2 + N2 <---> 2NH3?

Firstly, I would ask the student what they understand about Le Chateliers Principle. &quot;If a system is at equilibrium and a change is made to the conditions, then the system responds to counteract the cha...

How can I test to see if a sample a metal contains potassium?

The metals of group 1 (like potassium) can be identified by a flame test: A sample of the metal is placed in a bunsen flame, and the colour of the flame tells the metal. Potassium placed in the flame of a bu...

Why is water less dense in its solid state?

This is because in liquid state water molecules are close to each other, but in an disorganised manner. Each water molecule forms around 3.4 hydrogen bonds with other water molecules. However, in solid state...

Calculate the PH of 32 mmol of HCl in 75cm^3 solution. Assume HCl fully dissociates.

32 mmol = 0.032 mol 75cm 3 = 0.075dm 3 n = c x v so c = n / v c = 0.032mol/0.075 dm 3 = 0.426moldm -3 pH = -log[H+] pH = -log(0.426) = 0.37 (no units)

Compare the structures of Diamond and Graphite, making references to the bonding, the shape of the structures, and location of the electrons within the structures. Account for the fact that graphite conducts electricity and diamond does not.

In diamond, each carbon atom forms 4 strong covalent sigma bonds with other carbons, resulting in a tetrahedral 3D arrangement of atoms where all the electrons are fixed in place or localised. In graphite, e...
