While balancing equations by 'observation' or 'trial and error' is possible for simple compounds, it helps to have a general method of balancing these equations, so that, regardless of how complicated an ...

Alkenes are a family of hydrocarbons (compounds made up of only hydrogen and carbon atoms) that all share the same chemical formula, similar chemical properties (due to same functional group) and trends i...

An increase in temperature will increse the rate of a chemical reaction, and a decrease in temperature will decrese the rate. This is because the hotter the reactant particles are, the more kinetic energy...

1. The student should draw the lewis structure - this should be worked through using the whiteboard 2. From the lewis structure it can be identified that NH3 has 3 bonds and one lone pair of electrons ...

Kc=[Cl2(g)][PCl3(g)]/[PCl5(g)] for this reaction. The rate constant is not affected by changes in concentration and hence an increase in the concentration of Chlorine causes an increase in the concentrati...
