There are 5 main factors that affect the rate of reaction. 1. Concentration: Increasing the concentration increases the frequency of collisions between particles. 2. Surface Area: Increasing the surface a...

First, we can look at the number of hydrogens on either side. The equation shows 8 hydrogen atoms on the left hand side (in C3H8) whereas on the right hand side, we have 2 hydrogen atoms (in H2O). So we n...

1. Increase the temperature - this increases the kinetic energy of particles, so when they collide with each other the collision has a greater energy so is more likely to overcome the activation en...

Same molecular formulas, but bonded in different ways. So by this I mean that 2 molecules could have the same formula but have a different structure, they have bonded together differently.

They have the same number of 'free electrons' in their outer ring. They both have 7 free outer electrons, this means that all group 7 elements have 7 free outer electrons.
