A microporous Er(III)-based metal–organic framework (MOF), whose chemical formula can be written as {[Er(TCPB)(H2O)]·dioxane·0.5H2O}n, has been formed from the tripodal ligand 1,3,5-tris(4-carbonylphenyloxy)benzene (H3TCPB) by solvothermal synthesis and determined by the single ...
Formula equations: Ca(OH)2 (aq) + HCl (aq) + NaHCO3(aq) = NaCl (aq) + H2O (l) + CO2 (g) and would there be heat added in the question as we need heat to form the CO2 gas?? and thsi would be a neutralization reaction right?
