Although they are potent coronary vasodilators, their principal benefit follows from a reduction in venous return which reduces left ventricular work. The amount of heating required depends on the degree to which the ion is polarized. On that basis, the oxide lattice enthalpies are bound to fall faster than those of the carbonates. By using aqueous sodium chloride, describe how a student can distinguish calcium ions from lead ions. If you think carefully about what happens to the value of the overall enthalpy change of the decomposition reaction, you will see that it gradually becomes more positive as you go down the Group. A common example of an inorganic nitrate salt is potassium nitrate (saltpeter). For example, for magnesium oxide, it is the heat needed to carry out 1 mole of this change: $MgO_{(s)} \rightarrow Mg^{2+}_{(g)} + O^{2-}_{(g)}$. The inter-ionic distances in the two cases we are talking about would increase from 0.365 nm to 0.399 nm - an increase of only about 9%.
