For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will. Compound states [like (s) (aq) or (g)] are not required. You can use parenthesis () or brackets [].Examples...
c) preparing a final mixture of powders by diluting the undersize with a UO2 powder P3, d) pelleting this final mixture, and e) sintering the pellets, and in which at least one compound is incorporated chosen from the group consisting of the oxides of Cr, Al, Ti, Mg, V and Nb, pre...
Using the oxidation state of the atoms in a chemical species, we can determine how oxidized or reduced a compound is. For instance, if the oxidation state of an element in the first compound is +3, and the oxidation state of the same element in the second compound is +4, we can...
If a 5.72 mole sample of O2 gas is allowed to expand from 13.6 L to 28.4 L, what is its change in entropy?Entropy:Suppose the final volume, initial volume, and the moles of an element or compound given. In that case, the change in entropy of ...
