Aqueous-Minerals Reactions: Chemical reactions involving aqueous species and mineral species are heterogeneous and slower compared to aqueous species reactions, thus modeled as rate dependent chemical reactions. This means that when mineral species (N_m ) are not is equilibrium with the aqueous species, the minerals can either dissolve or precipitate. As shown in equation R11 of an example of calcite dissolution/precipitation, a mineral species (Calcite) is involved in a reaction with only…

import macroeconomic stability from US dollar. With the mismanaged U.S. monetary policy, ASEAN countries would like to delink this linkage. Second, exchange rate stability is important for intra-regional trading. Since most countries have stabilized their currency to US dollar, US dollar then automatically provide a high degree of exchange rate stability. According to Rövekamp, Frank, Hilpert, Hanns Günther (Eds.) (2014), the share of currencies invoiced in exports of Asian and Pacific…

Twenty million women and ten million men will suffer from an eating disorder at some point in their life (NEDA, 2015). Eating disorders are among the most common diseases in young adults and adolescents. Eating disorders are characterized by abnormal eating patterns, unusual fatigue, and weight changes. There are many types of eating disorders. The most commonly known and practiced eating disorder is anorexia nervosa, often referred to as anorexia for short. It is the third most common chronic…

The Effects of Substrate Concentration and Temperature on a Catalase Reaction Rate Introduction Catalase is a vital component in the human body. The most crucial of which would be Enzymes, these are protein catalysts. A catalyst speeds up a chemical reaction rate. Virtually all chemical reactions within the human body require a catalase enzyme to be completed in the proper amount of time. The decomposition of hydrogen peroxide to oxygen and water can be completed with the catalase enzyme…

Cardiac Dysrhythmia Cardiac Dysrhythmia also known as cardiac arrhythmia is a group of of conditions where the heartbeat is irregular and or too fast or too slow. Tachycardia is known as a heart rate that is over 100 beats per minute for adults ,while Bradycardia is too slow with below 60 beats per minute. Majority of arrhythmia issues are not serious, but some predispose one to complications like heart failure or a stroke. Arrhythmia are the leading cause of sudden cardiac death, with 400,000…

interest rates, foreign exchange markets and rates The questions that I will answer for this week’s assignment are as follows: Why the simultaneous targeting of the money supply and interest rates is sometimes impossible to achieve? How do central banks intervene in foreign exchange markets? What did the Bretton Woods Agreement do to the ability of foreign exchange rates to fluctuate freely? Targeting Money Supply and Interest rates Firstly, the Fed targets money supply and interest rates in…

depicts the interval, or the amount of time, between two pulses. Table 4 depicts the calculate heart rates of volunteer 1 and 2 based upon the amplitude and interval of each pulse. As interval decreases, heart rate increase and amplitude does not affect rate, but represents the…

The hypothesis was supported as the rate of reaction did increase as the concentration and the temperature increased. The concentration, or molarity, of the reactants increased in relation to time in the form M=1.1541e0.0016t. This is an accurate relationship as the volume remains the same as the number of molecules increase, thus the rate would increase exponentially as the molecules collide at a constant growth rate. This is also a reliable model as the R² value is 0.9697. The hypothesis that…

- affect the reaction rate. This was to enhance understanding and gain knowledge of how certain properties affect reaction mechanisms and activation energies, and how acid-base equilibria behaves. The data generally supported the hypothesis. It can be clearly seen that higher molarities of t-BuCl gave faster reaction rates, and it is an even clearer trend between the temperature of the system and the reaction rates. Higher temperatures gave noticeably faster reaction rates. The indicator, as…
