To start, we need to know that the gradient of the curve at the stationary points is 0 and that when the second derivative is less than 0, there is a maximum and when the derivative is greater than 0, the...

a) The fluorine atom is smaller than the chlorine atom, and there is less shielding from other shells of electrons. Thus the bonding pair of electrons are more attracted to the positive nucleus.

b)...

Normal neuronal resting potential is around -70mV - this is maintained by sodium-potassium pumps. When the neuron is stimulated, sodium ion channels begin to open, allowing sodium ions to diffuse back int...

We know that A+B = 8 so we should first count the number of ways that the two dice could total 8. (A = 2, B = 6), (A=3, B=5), (A=4, B=4), (A=5, B=3) , (A=6, B= 2) -- this gives 5 possible waysWe also know...

In both an elastic and inelastic collision momentum is conserved, however in an elastic collision the total kinetic energy is the same before and after the collision. In an inelastic collision kinetic ene...
