Ionic structures form giant lattices with many electrostatic attractions between oppositely charged ions. Covalent molecules have strong covalent bonds involving a shared pair of electrons.
The rate of reaction will increase. Increased temperature causes the particles to move faster, increasing the number of collisions between the particles. More particles have energy exceeding the activatio...
The forward reaction, N2 (g)+ 3H2(g) ---> 2NH3(g) is an exothermic reaction. This means that energy is released to the surroundings during the reaction and ...
Firstly, I would ask the student what they understand about Le Chateliers Principle. "If a system is at equilibrium and a change is made to the conditions, then the system responds to counteract the ...
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 fl...
