When you have finished, submit this assignment to your teacher by the due date for full credit. (5 points) Score 1. Nitroglycerine (C3H5(NO3)) is a powerful explosive. The products of this reaction are elemental oxygen, elemental nitrogen, water, and carbon dioxide. The Gibbs free energy for this reaction is negative at 273 K. Determine whether

devices be made the way they are. An effective rifle needs to be efficient, efficiency is defined as [useful energy given off]/ [total energy in]. An efficient rifle converts as much of the chemical potential energy stored in the propellant into kinetic (movement) energy. For example for a .300 Hawk ammunition the energy use in percentage is: Barrel friction 2% Projectile Motion 32% Hot gases 34% Barrel heat 30% Unburned propellant 1%. Therefore the efficiency for this bullet in the

Clock reactions are among the most visually entertaining demonstrations of chemistry. Simply put, a clock reaction is one where two substances are mixed and there is a time delay where there is no visually discernable change in the system. During this delay, one of the chemical species, the clock chemical, has a very low concentration. The end of this induction period is marked by a rapid increase in concentration of the clock chemical (S.J. Preece et al., 1999). This rapid increase in concentration

One can easily argue that no single discovery changed the face of the earth more than electricity. We can witness its innumerable uses in our lives on a day-to-day basis, so electricity, particularly its relationship with heat, was always a subject that I found incredibly fascinating. I remember first learning about the topic in my IB Physics course just the past year and regretting that we couldn 't delve deeper into the topic or see the phenomenon in person through any lab work. This is precisely

wherein the beam was targeted region atoms . history Rutherford backscattering (RBS ) is based on collisions between atomic nuclei and is named after Lord Ernest Rutherford, who in 1911 was the first to introduce the concept of atoms whose nuclei . theory When a sample is bombarded by a beam of high energy particles , the majority of the particles are implanted into the material and do not escape. Indeed , the diameter of a nucleus is of the order of 1e- 15 m while the distance between the cores is

Our group performed the test of decreasing the substrate concentration in the catalyzed reaction decomposing hydrogen peroxide into water and oxygen gas. For our baseline, we set up a reaction using 10 ml 3% hydrogen peroxide (the substrate) and 1 ml yeast (the catalyst). We then calculated the reaction rate to be 0.09375 ml/sec of oxygen produced. This reading is based off of the initial part of the curve, before the plateau. Once the rate decreases in the data too much peroxide has been used

Syntheses and characterization of [Mn(BPMP)(OTf)2] catalysts BPMP was synthesised via the published procedure [2b] and expected, the piperazine ring adopts the more stable chair configuration, and the methylpyridyl substituents are found in the equatorial positions. Reaction of BPMP with Mn(OTf)2 (ratio 1 : 1) in CH3CN under air the atmospheric conditions this complex [Mn(BPMP)(OTf)2]. Removing of the volatiles and washing with diethyl ether leads to white solid that analyses as [Mn(BPMP)(OTf)2]
