In this study, Ni/Y 2 O 3 catalysts modified by alkaline earth metals were prepared and their catalytic activity for ammonia decomposition was examined. These metals burn in nitrogen to form nitrides of the types M 3 N 2 which are hydrolysed with water to evolve NH 3. All the discovered alkaline earth metals occur in nature. The name alkaline metal comes from the fact that the oxides of the heavier members of the group react with water to form alkaline … alkali and alkaline earth metals respectively. Lithium also forms a relatively stable hydride, whereas the other alkali metals form hydrides that are more reactive. alkali metals do not react with nitrogen directly. The reaction in Equation 21.27 is the basis of antacids that contain MCO 3, which is used to neutralize excess stomach acid.

If formed, they have 5.2 Alkali metals: The word “alkali” is derived from the word al-qalīy meaning the plant ashes, referring to the original source of alkaline substances. Identify the option below that is an acid ionization reaction...? Like the alkali metals, the alkaline earth metals are soluble in liquid ammonia and result in the formation of solutions that are dark blue from calcium, strontium, and barium. We must look at the ÎHfÂ° for M3N and M'3N2 using the Born-Haber cycle and we can immediately see two problems: ÎHdissN2 is +945 kj mol^-1(2nd highest known) http://www.webelements.com/nitrogen/bond_enthalpie... and EA for N^3- is +1736 kJ mol^-1 (Huheey 4th ed p 42) These two terms alone sum to 2681 kJ mol^-1 and the lattice energy for M3N is probably not enough to compensate for these terms. Alkaline earth metals all react quickly with oxygen. BeSO4 and MgSO4 are readily soluble in water. Of the alkali metals, only lithium reacts with nitrogen, and it forms a nitride (Li 3 N). When the two s-electrons of the valence-shell are lost, alkaline earth metals are converted into M 2+ ions which have inert gas configuration. REACTION WITH NITROGEN . If formed, they have Alkaline earth metals react with ammonia at low temperature forming hexamines M (NH 3 ) 6 Recently, ammonia has attracted much attention as a promising hydrogen carrier due to various advantages for on-site hydrogen generation. Using graphite powder as the carbonaceous phase the rates of the reaction between 700 and 1100 °C were found to be substantially increased on addition of small amounts of BaCO 3 and SrCO 3 to the graphite. The alkaline earth metals are all silver-colored and soft, and have relatively low densities, melting points, and boiling points. Among the given alkaline earth metals, magnesium is least electropositve with highest ionization energy. Reaction with water and air: The alkaline earth metals are less reactive than alkali metals.

In the alkali metal nitrides (besides lithium) you have three large cations and one small anion. For M'3N2, Z+ Ã Z- = 6 which translates into a lattice energy approximately twice that for the hypothetical or unstable M3N cmpds and I believe accounts for the stability of theM'3N2 cmpds. Looks like youâve clipped this slide to already. Actually, one of the alkali metals (lithium) does react with nitrogen: Sodium nitride exists, but it undergoes the reverse reaction easily: I assume the difference has to do with the lattice energy of the different nitrides.
