Hydrogen cyanide

Reagents 2,4-dichlorophenoxyacetic acid (2,4-D) (Sigma-Aldrich), 2,4 dichlorophenol (2,4-DCP) (Sigma-Aldrich), ferric sulfate (nH2O) (Carlo Erba), hydrogen peroxide (H2O2) (Carlo Erba), acetonitrile (Sigma-Aldrich) and Milli-Q water were used to perform all the experiments . All the reagents were used without further purification. Natural groundwater samples Samples were taken from groundwater wells localized in a small rural community (coordinates: 3º21’03.38” N, 76º26’24.51”) near to the…

Calibration 1: Text Cyclohexane is a six carbon cyclic alkane that is unusually stable compared to other cyclic alkanes. This stability can be seen by examining cyclohexane in its chair conformation. Since cyclohexane consists of all sp3 hybridized carbons, it ideally exists with 109.5-degree bond angles. If cyclohexane were planar, it would be forced to have 120-degree angels, and would therefore have angle strain. However, cyclohexane chair conformations are almost completely free of angle…

Lithium is an element with the atomic number 3 on the periodic table. Its atomic symbol is Li. Lithium belongs in the most reactive group on the periodic table which is called alkali metal. Lithium under standard conditions is the lightest metal it is also one of the least dense solids. Lithium has an atomic mass of 6.94 and density of 0.534. Lithium is a soft silver white looking metal. Lithium melts at 357 degrees and boils at a temper of 2426 degrees. Thanks to lithium's ability to reach…

Lithium is the chemical element of atomic number 3, a soft silver-white metal. It is the lightest of the alkali metals. The two main parts of every atom are neutrons and protons. The three main subatomic particles that form an atom are protons, neutrons, and electrons. Electrons are the smallest of the three particles that make up atoms. Electrons are found in shells or orbitals that surround the nucleus of an atom. Protons and neutrons are found in the nucleus. They group together in the center…

The FTIR spectra of four phosphazenium salts and P5+ are shown in Figure S1. Four phosphazenium salts have characteristic absorptions at 2850 and 2930 cm-1, belonging to the stretching vibration of -CH2- and -CH-, respectively, and this peak in the P5+ represents the absorption of –CH3. All the five compounds exhibit absorption at 960, 1230, and 1442 cm-1 corresponding to the stretching vibrations of P–N. In the FTIR spectrum of Cy4P1+BF4-, the peaks at 1633 and 3432 cm-1 belong to water because…

Hydrogen is an Alkali earth metal in group 1 on the periodic table. Hydrogen has an atomic mass of 1 and an atomic number of 1. Hydrogen has 1 VALENCE electron and 1 neutron. It has 1 ring, because it’s in period 1. Hydrogens state of matter is gas. Lithium is a Alkali Earth Metal on the Periodic Table. Lithium's state or matter is solid. Lithium has a atomic number of 3 and an atomic mass of 7 when rounded. It has 1 valence electron around its nucleus and 4 neutrons in the nucleus. Lithium has…

Atomic mass: the mass of an atom of a chemical element expressed in atomic mass units; approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes Molar mass: a physical property defined as the mass of a given substance (chemical element or chemical compound) divided by the amount of substance Mole: the amount of a substance contained in 6.02 x 10²³ particles of that substance…

compound that was the focus of our re- search. GAT is a salt containing a high per- centage of nitrogen. It has two conjugated ni- trogen rings, which are negatively charged, and a positively charged component consisting of nitrogen, carbon, and hydrogen. In addition to the high-energy content of this compound, as a salt, it has a lower heat of degradation due to the ease of breaking its ionic bonds. GAT was found to react with N100, a com- mon curative for HTPB. An alternative isocyan- ate…

Conclusion At first, my hypothesis was that P-waves would move faster than S-waves. I thought this because P-waves went straight and S-waves where lobbed to the side. My hypothesis was correct, since P-waves had a more focused channel of energy unlike S-waves, which bended to the side. This causes S-waves to go slower and P-waves to go faster. When the experiment was done, P-waves averaged at .64 seconds and S-waves averaged at .68 seconds. On the P-wave experiment, I pulled the spring back…

Experimental Section - Chemicals Pyrrole, substituted benzaldehydes (p-anisaldehyde, p-nitrobenzaldehyde, 2,6-dichlorobenzaldehyde and benzaldehyde), triethylamine (TEA), p-terphenyl (TP) and ferrocene (Fc) were purchased from Sigma-Aldrich. Tetraphenylporphyrin (TPP) was purchased from Frontier Scientific. Acetonitrile (MeCN), dichloromethane (DCM), 1,4-dioxane, and other organic solvents used were spectroscopic grade. These solvents were distilled from appropriate drying agents under argon…
