What are the optimal conditions for the Haber Process N2(g) + 3H2(g) <--> 2NH3(g)? Use Le Chatelier's principle to derive your answer.

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, the c...

Solve the simultaneous equations 6x - 27 = 15 and 4x + 3y = -3.

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 12:...

Bromine has an atomic number of 35 but has two stable isotopes- bromine-79 and bromine-81. Given that 51% of bromine atoms are bromine-79 and 49% are bromine-81%, work out the relative atomic mass of bromine to the nearest whole number.

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 number of neutrons. e.g 7...

Can you explain the different ways heat can travel?

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 be...
