• • Find the value of the equilibrium constant for formation of FeSCN2+ by using the visible light absorption of the complex ion. Confirm the stoichiometry of the reaction.

An empirical formula must have a whole number ratio of atoms in each element. The ratio is multiplied by two.

3. Find the number of atoms of each of the substances involved in the reaction.

The human sense of touch is known as the somatic or somatosensory system. The skin is the biggest and most complex organ in the somatosensory system.The somatosensory system permits the human body to experience pressure, texture, temperature, and pain, and to see the position and development of the body's muscles and joints.The receptor cells in the skin can be separated into three useful classifications: mechanoreceptors that sense pressure and surface, thermoreceptors that sense temperature, and nociceptors that sense pain. Thermoreceptors distinguish changes in temperature utilizing two sorts of receptor cells: warm and cold. Thus, thermoreceptors on the skin detects the temperature signal using two specific receptors cell: warm and cold.

Ionic compounds are soluble in water to a certain point depending on the compound. The level of solubility changes among different compounds. Some ionic compounds can completely dissolve in water and appear to be a homogeneous mixture. Although, some ionic compounds dissolve very little, and could be considered insoluble, since it does not dissolve fully. Depending on the compound, the level of solubility can be high or low. However, ionic compounds could dissolve to a certain degree. If the solution appears to be a heterogeneous mixture, many may assume through visual representation that it may be insoluble. As stated previously, the smallest amount of solubility should be considered. To confirm whether or not the substance is soluble, observe the efficiency when conducting electricity. Due to practical reasons, the slightest solubility could be considered insoluble by people.

36. Coefficients are written in front of the formulas of reactants and products to balance chemical

The atom of an element has electrons that are found around the nucleus in regions known as orbitals. When energy is absorbed by the electrons of an atom they begin to jump to higher energy levels. When this happens the electrons are in an excited state. However when the electrons begin to release the energy and drop in energy levels they emit electromagnetic radiation. If the radiation that is emitted falls between 400 to 700 nanometers then the electrons emit photons which we can see as visible light.

The $TM$ is composed of three different layers, namely the uveal meshwork, the corneoscleral meshwork and the juxtacanalicular meshwork ($JCT$). As intercelular areas are considerable, the uveal meshwork does not present much resistance to $AH$ outflow. The second layer presents lamellae covered by endothelium-like cells, their intracellular spaces are narrovwer and thus, increase the flow resistance. The juxtacanalicular meshwork is an irregular tissue and is the major cause of resistance to flow. It lies directly the inner wall of endothelial cells from the $SC$ \cite{llobet2003understanding}.

9. The sum of the oxidation numbers of all atoms in a neutral compound is 0.

Begining by labeling 7 different 2.0 ml tubes 0 thru 6 for each compound. Then add 1ml of extract to tube 0. Then add 0.5 ml of DMSO to tubes 1 thru 6. Now make a 1:2 serial dilution from 0(pure extract) to 6(1:16)

The two independent variables were luminant cue patches (light cue, dark cue and equiluminant cue) and location of the cue and target (valid side with cue and target on same side and invalid side with cue and target on opposite sides). The dependent variable was participants’ reaction time in millisecond.

Part A.1. Sodium metal is also readily oxidized by oxygen. If the product of the reaction were dissolved in water, what would be the color of the litmus for a litmus test? Explain. What is the product?

In this experiment, a sample of K2S2O8 was prepared by the electrolysis of an aqueous solution of H2SO4 and K2SO4. The peroxodisulfate anion, S2O82-, was also observed for its ability to serve as a counterion for precipitation by preparing a copper (II) complex by reacting hydrated copper (II) sulfate with ammonium peroxodisulfate in the presence of pyridine. This same ability, coupled with its strong oxidizing ability allowed for stabilization of the unusual oxidation state of 2+ for silver which was observed by preparing an analogous silver (II) complex by reacting silver (I) nitrate with ammonium peroxodisulfate in the presence of pyridine. IR spectra for the three products were

In the fourth reaction, 15 mL of 6.0 M sulfuric acid was added to the copper (II) oxide while stirring. The balanced equation for this reaction is as follows:
