The oxidation state of an element describes the number of electrons transferred in reactions. For example, the oxidation or valence states of the following elements are equal to the number of equivalents: • Calcium: Ca+2 ion: valence of 2: number or no. of equivalents: 2 • Aluminum: ...
When a compound is separated, is this a chemical change because there are now different elements? At 2000 K, the partial pressures of an equilibrium mixture of H_2S, H_2, and S are 0.045, 0.053, and 0.035 atm, respectively. Calculate the value of the equilibrium constant K_p at 2000 ...
The detected intensities from the mass spectrometer were calibrated by linear regression, and then the equation of the calibration curve was used to calculate concentrations of dissolved ions in the electrolyte. The dissolution rate of Al is converted by subtracting the solute contribution from the ...
An enthalpy diagram is a method used to keep track of the way energy moves during a reaction over a period of time. Learn how to draw and label enthalpy diagrams, the definition of an enthalpy diagram, and how to examine the diagram. ...

To determine how many Faradays are required to reduce one mole of MnO−4 to Mn2+, we can follow these steps: Step 1: Identify the oxidation statesIn MnO−4, the oxidation state of manganese (Mn) is +7. In Mn2+, the oxidation state of manganese is +2. Step 2: Calculate the ch...
Moles to Atoms | Formula, Calculation & Avogadro's Number from Chapter 2 / Lesson 4 213K What is the moles to atoms formula? How does one convert atoms to moles? Learn how to calculate the number of atoms in a sample from the relationship between moles and Avogadro's number. Related...
size of x , the larger the set of elements to classify the more likely the ties; (ii) number of attributes and their precision, typically the lower the number of attributes the more likely there are going to be many ties; the lack of precision may lead to many ties even for cases ...
We next asked how it is possible that long-lived misfolded proteins are able to bypass the post-translational cellular chaperone machinery. To address this question we used coarse-grained Langevin dynamics to calculate the dissociation constant between the chaperone GroEL and three distinct conformational...
{:(H(2)O rarr2H^(+) + 1//2 O(2)+2e^(-)),(1 mol " "2 mol):} (Here, oxidation number of oxygen changes from -2 in H(2)O to 0 in O(2). Therefore, 2 moles of electrons are lost during the oxidation of 1 mol of water.) The
