Step 1: Write the unbalanced ionic equation.
Fe2+(aq)+Cr2O2−7(aq)→Fe3+(aq)+Cr3+(aq)(22.10.1) Notice that the equation is far from balanced, as there are no oxygen atoms on the right side. This will be resolved by the balancing method.
Step 2: Write separate half-reactions for the oxidation and the reduction processes. Determine the oxidation numbers first, if necessary.
Oxidation:Fe2+(aq)→Fe3+(aq)Reduction:Cr2+6O2−7(aq)→Cr3+(aq)(22.10.2)(22.10.3) Step 3: Balance the atoms in the half-reactions other than hydrogen and oxygen. In the oxidation half-reaction above, the iron atoms are already balanced. The reduction half-reaction needs to be balanced with the chromium atoms.
Cr2O2−7(aq)→2Cr3+(aq)(22.10.4) Step 4: Balance oxygen atoms by adding water molecules to the appropriate side of the equation. For the reduction half-reaction above, seven H2O molecules will be added to the product side.
Cr2O2−7(aq)→2Cr3+(aq)+7H2O(l)(22.10.5) Now the hydrogen atoms need to be balanced. In an acidic medium, add hydrogen ions to balance. In this example, fourteen H+ ions will be added to the reactant side.
14H+(aq)+Cr2O2−7(aq)→2Cr3+(aq)+7H2O(l)(22.10.6) Step 5: Balance the charges by adding electrons to each half-reaction. For the oxidation half-reaction, the electrons will need to be added to the product side. For the reduction half-reaction, the electrons will be added to the reactant side. By adding one electron to the product side of the oxidation half-reaction, there is a 2+ total charge on both sides.
Fe2+(aq)→Fe3+(aq)+e−(22.10.7) There is a total charge of 12+ on the reactant side of the reduction half-reaction (14−2) . The product side has a total charge of 6+ due to the two chromium ions (2×3) . To balance the charge, six electrons need to be added to the reactant side.
6e−+14H+(aq)+Cr2O2−7(aq)→2Cr3+(aq)+7H2O(l)(22.10.8) Now equalize the electrons by multiplying everything in one or both equations by a coefficient. In this example, the oxidation half-reaction will be multiplied by six.
6Fe2+(aq)→6Fe3+(aq)+6e−(22.10.9) Step 6: Add the two half-reactions together. The electrons must cancel. Balance any remaining substances by inspection. If necessary, cancel out H2O or H+ that appear on both sides.
6Fe2+(aq)6e−+14H+(aq)+Cr2O2−7(aq)14H+(aq)+6Fe2+(aq)+Cr2O2−7(aq)→6Fe3+(aq)+6e−→2Cr3+(aq)+7H2O(l)→6Fe3+(aq)+2Cr3+(aq)+7H2O(l)(22.10.10)(22.10.11)(22.10.12) Step 7: Check the balancing. In the above equation, there are 14H , 6Fe , 2Cr , and 7O on both sides. The net charge is 24+ on both sides. The equation is balanced.

annotation you can easily find it by going to your homepage in hypothes.is and then filtering by tags. So you may want to make tags like "exam 1", or "nomenclature". If you then filter with your hypothes.is user name and exam 1, you see those items you tagged (see video 11\PageIndex{1} at 3:00 min. If you just do exam 1, you filter for everything the class tagged exam 1. You can then click the contextual link by the annotation, and hypothes.is will open that page, navigate to the highlighted text and display the annotation.

The master is frequently compelled to sell this class of his slaves, out of deference to the feelings of his white wife; and, cruel as the deed may strike any one to be, for a man to sell his own children to human flesh-mongers, … for, unless he does this, he must not only whip them himself, but must stand by and see one white son tie up his brother, of but few shades darker … and ply the gory lash to his naked back.”

Es imposible medir el cambio de entalpía partiendo de un cristal sólido y convirtiéndolo en sus iones gaseosos dispersos. Es aún más difícil imaginar cómo podría hacer lo contrario: comience con iones gaseosos dispersos y mida el cambio de entalpía cuando estos se conviertan en un cristal sólido. En cambio, las entalpías de celosía siempre deben calcularse, y hay dos formas completamente diferentes de hacerlo. Puede utilizar un ciclo de la ley de Hess (en este caso llamado ciclo de Born-Haber) que implica cambios de entalpía que se pueden medir. Las entalpías de celosía calculadas de esta manera se describen como valores experimentales. O puede hacer cálculos al estilo de la física para determinar cuánta energía se liberaría, por ejemplo, cuando los iones considerados como cargas puntuales se unen para formar una red. Estos se describen como valores teóricos. De hecho, en este caso, lo que realmente está calculando se describe correctamente como energías reticulares.

This sentence stood out to me, because, previously, I did not realize that the Abstract could be so beneficial in writing the other sections of an IMRAD paper. I've learned that the Abstract acts as a summary or overview of a paper, but I had no idea the Abstract could help the writer in this way.

he above video shows, placing zinc metal into the copper(II) solution results in a spontaneous redox reaction (ΔG<0ΔG<0\Delta G <0), and if we placed the copper metal into the zinc solution no reaction would occur (ΔG>0ΔG>0\Delta G >0). In an electrochemical cell, we allow electrons to be transferred, which will spontaneously occur in the direction of ΔG<0ΔG<0\Delta G <0, and a cell operating in this fashion is called a galvanic or voltaic cell, which can be used to provide energy to do work, like the common "battery" we use in flashlights and electrical devices.

to reduce the number of independent variables to one. This is done by making successive measurements where all reactant concentrations are held constant except for one, with that data showing the rate law as expressed for that reactant, and it can then be solved as a single reactant problem This lesson will start by solving the single reactant rate law. Then show how to reduce multi-reactant problems to single reactant problems. We will also introduce two different techniques for solving these.

Load the sample by jabbing the open end of a capillary tube into a pile of the sample. With closed end down, drop the tube down a long hollow tube so that it hits the benchtop and packs the sample into the closed end of the tube. Load the sample to a height of 222-3mm3mm3 \: \text{mm}. Place the sample into a slot in the MelTemp. Turn the dial to begin heating. Heat at a medium rate to 20oC20oC20^\text{o} \text{C} below the expected melting point. Then heat very slowly (1oC1oC1^\text{o} \text{C} every 30 seconds). Record the temperature where the first droplet of liquid is seen (there is movement in the tube). Record the second temperature when the entire sample liquefies (the entire sample changes from opaque to transparent). Record a melting range, e.g. 120120120-122oC122oC122^\text{o} \text{C}. If another melting point trial is to be performed, cool the metal block to at least 20oC20oC20^\text{o} \text{C} below the next melting point, by wiping it with a wet paper towel or cooling with a jet of air.

The hand is a straight (consecutive ranks, as in 5, 6, 7, 8, 9, but not all from the same suit).
The back of the book gives the answer as 10(4^5-1), which is incorrect. There are 10 4^5 "straights" where the suit doesn't matter, the sequence can even all be the same suit among the 10 4^5 such hands. So you want to subtract out the "straights" of the same suit, there are 40 such hands. There are 10 possible sequences 1)A2345 2)23456,3)34567,...10)10JQKA. Each sequence can be one of the 4 suits so thats 4 10=40 total. A straight of all the same suit is a straight flush, which is part h of the question. So the final answer to the number of straights but not from the same suit is 104^5-40.

m+nm∼n⇔m+nm\sim n \,\Leftrightarrow\, m+n is even
The answer in the back of the book states that there are 3 equivalence classes(ECs): [0], [1], & [2]. But I think it is incorrect and there are only 2, one for evens and one for odds because if you add any 2 even numbers you get an even sum, same if you add 2 odd numbers. Only way you get an odd sum is if you add one even and one odd #. So all the even numbers would belong to the even EC and all the odd numbers would belong to the odd EC.
-
|m−3|=|n−3
The answer in the back of the book states that the equivalence classes(ECs) are of the form {3−k, 3+k} but I dont think that is correct. I believe the correct answer is that the ECs are [a] where a \(\in\) Z, so an equivalence class for each integer in Z.

This idea that the subjunctive can be used to help express a statement even if you don't know if it is true is interesting. It's something that we use heavily within your daily life, but we rarely realize that we are doing it.

he left part of Figure 12.7 b shows two isobaric transitions for converting ice to steam. The top transition at 1 atm is above the triple point and so liquid water is stable, while the lower transition is below the triple point and the ice sublimes to steam without ever forming a liquid phase. It is important to understand the relationship of these graphs and the differences. The phase diagram represents the phase that would exist for a system at equilibrium as a function of the pressure and temperature. The ri
