In addition, the specific Gibbs function for a simple compressible substance is given by the equation shown.

6. Select the lab book and click on the data link for Ideal Gas 1. In the Data Viewer window, select all the data by clicking on the Select All button and copy the data using CTRL-C for Windows or CMD-C for Macintosh. Paste the data into a spreadsheet program and create a graph with volume on the x-axis and pressure on the

The Lithium Nickel Manganese oxide battery is still in its experimental stages. It consists of a 25% nickel substituted in a LiMn2O4 spinel. This is because Manganese will have 4 electrons in its valence shell which will avoid the Jahn-Teller distortion caused due to the Mn3+. Due to the oxidation or reduction of Nickel ions which leads to the transfer of electrons which corresponds to electric current. LiNi0.5Mn1.5O4 takes shape in two conceivable crystallographic structures concurring the cationic sub lattice: the face-focused spinel (S.G. Fd3m) named as "cluttered spinel" furthermore, the straightforward cubic stage (S.G. P4332) named as "requested spinel". This addition allows

Calculate the vapor pressure of water above a solution made by combining 90.0 g of water and 90.0 g of ethylene glycol at 383.15 K. The vapor pressure of pure water can be found in Appendix B.

There is a problem with using this equation due to the fact that we are not using an ideal gas. We are using Helium, so adjustments must be made to the ideal gas law in order for proper calculations to be computed. A route to

Finding and balancing equations to find the ideal gas constant using PV=nRT. Using Excel to format and graph various types of data, both given and calculated. The data given for the decomposition of NaHCO3 and Na2CO3 provided the information needed to determine the experimental constant “R” that can then be compared to the textbook definition of “R”.

To determine the pressure of H2 in the cylinder, the vapour pressure of the water was subtracted from the atmospheric pressure. This formula was derived from Dalton’s Law of partial pressure,

where the logarithm on base 10 has been converted to the "natural" logarithm. Multiplying by f , Equation (2) yields:  ε 2.51 f 0.869 ln  +  3.7 D ℜ f   =0  

The model is therefore M≈138.75sin2π9x-1989+495.45 and we can superimpose it on the original data as follows.

From equation 6 I obtained the linear equation 7, model to be used in the study.
