The rate at which a reaction occurs, referred to as reaction rate, is a type of reaction property that directly measures the extent of a reaction. Changes in concentration affect reaction rates in chemical formulas, and if the reaction is not specifically known, the rate cannot be determined. The rates are given in negative or positive measurements depending on whether the concentration is a reactant or product. Knowing this, the first step in finding the reaction rate would be to determine the…
root is a complex number? Answer: If the equation is 7th degree then it has 7 roots. Those roots can be complex or real. Complex roots always come in pairs, so if it has one, then it has 2, the other one being the conjugate of the first one. This in other words, if one complex root is a + bi, then the other complex root is a – bi. If at least one root were complex, then we would have a minimum of 2 complex roots with a maximum of 5 real roots. The equation can have at most 6 complex roots (3…
Introduction This extended experimental investigation (EEI) investigated the effect in which concentration had on the rate of reaction. The purpose of this experiment is to test different concentrations of hydrochloric acid with sodium thiosulfate and to see how long it would take until the cross underneath the flask is no longer visible through the milky white solution. Collision theory A collision is when two or more object run into each other. But collision theory is, that only some…
To give an another definition of complex number, we have to show z= ew for w, where z is any non-zero complex number. If we assume w = u + iv then eueiv = |z|e^i arg z and this means that |z| = e^u , v = arg z . The equation |z| = e^u is a real equation, so we can write u = ln |z|, where ln |z| is the ordinary logarithm with positive real numbers. Hence, w = u + iv = ln |z| + i arg z = ln |z| + i(Arg z + 2n) , n = 0 , ±1 , ±2 , ±3 , . . .6 We profoundly examined the connection between…
Questions: (a) Show that: (b) What value of ε ss would you expect at 800°C and 16000 psi? A= 0.0043 Using your Larson-Miller curve, what temperature should you use for a life of 20 years at the lowest stress level? For the extensive length of time, a temperature of approximately 25 oC which is close to room temperature. With increasing stress or temperature, what changes will you notice in a typical creep curve? When you increase temperature or stress, the creep curve will increase in…
for the hydrolysis of p-nitrophenyl acetate (NPA) catalyzed by imidazole. In chemical kinetics, it is known that for every reaction, a rate law determines the speed that the reaction will proceed. The general form of the rate law is seen in Equation 1. Equation 12 Where is the rate of reaction, is the rate law constant, and are the concentrations of reactants and , and and are known as the reaction order with respect to species and . Kinetics are useful when finding the overall…
and equation 3.2 and 3.4 become: ∇.J=∇.(σE)=0 (3.6) Based on equation 3.6, the field distribution is depended on conductivity variation inside the material [1, 45, 46]. Furthermore, according to equations 3.5 and 3.6, space charge can be accumulated in insulation material in steady state condition due to the variation of permittivity to conductivity. As a result, by combining equation…
to come in contact or find proof? This lack of contact is sometimes referred to as “The Great Silence.” Many have tried to come up with solutions to this paradox and some of them definitely seem plausible. One of the obvious ones is that the Drake Equation is completely wrong. However, one of the bigger theories out there is known as “The Great…
The aim of this experiment was to build a shake torch and measure the electrical voltage produced when the magnet passes through a coil of wire. Our dependent variables were the amount of magnets (length of magnet) and the amount of shakes. This was done to help us discover if there was a relation between the amount of magnets, and the induced current produced. It was to investigate if a greater magnetic field and increased amount shakes would improve the shake torches ability to light the LED…
