When considering the optimal reaction conditions, one must check for pressure, temperature, concentration and catalysts involved. Le Chatelier's principle states that if a change to the system is made, th...

Initially we have two unknown variables, so we want to eliminate one of the variables (x) to solve for the other (y). The LCM of 6 and 4 is 12, so multiply each equation such that the coefficient of x is ...

What is an isotope? (To ensure the students basic understanding on isotopes) Isotopes are different atomic forms of the same element, which have same number of protons but different numbe...

Heat can travel through 3 different processes: conduction, convection and radiation. Conduction is caused by atoms bumping into each other, transferring energy and therefore heat. An example of this would...
