A certain compound has the molecular formula X_(4)O_(6) having 57.2%X . Thus,
If the ionic product of water (K_(w) ) is 1.96 xx 10^(-14) at 35^(circ)C what is its value at 10^(circ)C ?
The energy required for the following process is 1.96 xx 10^4 kJ mol^(-1) Li_(g) to 3e^(-) + Li_((g))^(3+) If the first ionisation energy of lithium is 520 kJ mol^(-1) , what is the second ionisation energy?
