I'll come too!

I'll give a hint for (a) and (b): (a) Create an equation for the balance of the fund in terms of the initial value, interest rate and the award. Do this for F1, F2... until you can identify a pattern with the balance (You should see a geometric progression), and make a general equation for the...

Year 11 Chem used Gibbs free energy formula to determine if a reaction was spontaneous or not. ΔG=ΔH−TΔS Where: ΔG = Change in energy ΔH = Change in enthalpy ΔS = Change in entropy

Potassium has the electron configuration 1s^2 2s^2 2p^6 3s^2 3p^6 4s^1, but when it becomes an ion (by being either positively or negatively charged) the potassium loses an electron (as it is easier for potassium to transfer 1 electron vs attracting 7). Therefore a potassium ion has one less...
