Web15 Dec 2016 · Table 1 summarized the pore properties of fresh and PbO-doped catalysts including BET surface area, total pore volume and average pore diameter. As shown in Table 1, the surface area of Mn-Ce/TiO 2 catalyst was 92.28 m 2 /g and the pore volume was 28.0 × 10 −2 cm 3 /g. It was clear that the increasing loadings of PbO on Mn-Ce/TiO 2 catalyst … Consulting a table of Common Element Charges reveals to us that hydrogen has a charge of +1 while nitrogen has a charge of -3. Carrying out the operation gives us the total charge of ammonia: Total charge = 5 (number of valence electrons) – [3 (bonds to hydrogen) + 2 (lone electrons) = 0.
