Can you please let me know how can i input biomass in my case. ): O. Kubaschewski, C.B. Data from NIST Standard Reference Database 69: The National Institute of Standards and Technology (NIST) ΔHfo(CO(g)) = -110.5 Find the enthalpy of the reaction of Fe2O3 with CO. Fe(s) + 3 H2O() -> Fe(OH)3(s) + 3/2 H2(g) DrH° = +160.9 kJ/mol-rxn given the enthalpies of reaction below. I have found my experience with Elsevier to be increasingly frustrating over the years, especially with the copy-editing. I am wondering what is your experience with other publishers, e.g. How to calculate FeO from Fe2O3 (Whole rock analysis?). The requested data can be retrieved from a variety of printed secondary references (e.g. S° = A*ln(t) + B*t + C*t2/2 + D*t3/3 − How do i calculate for percentage porosity in a ceramic material?

Is there a desciption of the reaction types of aspen plus? Thanks Any one please tell suitable solvent for PLA polymers? E/(2*t2) + G there is a formula but asks for hydrogen and water content in the fuel, which is hard to find hydrogen contents in that fuel thank you. i realised the archimedes method has many different formula.

Whether, this FeO can be used for altered metavolcanics? a. Have questions or comments? Alcock, P.J. All rights reserved. National Institute of Standards and How to calculate low heat value from high heating value? Once a paper gets accepted (assuming it is in TeX format with perfect formatting), a month can easily pass by until the corrected proofs are actually available. Data, Monograph 9, 1998, 1-1951. The heat of formation of Fe2O3(s) is 826.0 kJ/mol. But for biomass I have only data of heating value, proximate analysis, Ulitimate analysis. However, NIST makes no warranties to that effect, and NIST in my recent Corrosion Science paper I had to submit a long list of comments when they simply messed up the paper layout completely and inserted incomprehensible symbols ("-->") everywhere in the text.     H° = standard enthalpy (kJ/mol) For more information contact us at [email protected] or check out our status page at https://status.libretexts.org. I dont have data for sulfate analysis. we have considered a biochar combustor to Supply an auxiliary heat for gasification reactor and now the problem with this biochar combustor is that we need its enthalpy as a function of temperature to determine the biochar combustion temperature. Now I am deliberately trying to choose suitable journals that are not published by Elsevier for my next publication, and so far I've found one belonging to AIP and another to IOP. Is there any handbook or any other data available regarding the thermal conductivity values of metal oxides? Legal.

Go To: Top, Solid Phase Heat Capacity (Shomate Equation), Notes, Chase, 1998 E/t2 The publisher seems to be careless and irresponsible about the typesetting and copy-editing (which is the only job they actually do in addition to selling our work! I want to know the thermophysical properties of Fe2O3? N.B. Find the enthalpy for : 4Fe + 3O2 = 2Fe2O3 I got the following informations: Fe + 3H2O = Fe(OH)3 + 3/2H2 - Enthalpy is 160.9 kj H2 + 1/2O2 = H2O - Enthalpy is -285.8 kj Fe2O3 + 3H2O = 2Fe(OH)3 - Enthalpy is 288.6 I try using Hess Law but cannot solve it.
