How do I count sigma and pi bonds and how do you determine the hybridization of certain atoms? How many calories will it take to melt 75 grams of ice? How do I calculate the standard reduction potential of 2 MnO2(s) + 2 NH4+(aq) + 2 e- -Mn2O3(s) + 2 NH3(g) + H2O(l) ...
The standard unit of energy is the joule or calorie, but generally energy used in the home by appliances is measured in kWh, also known as "units". To work out the number of kwh, you divide the power in watts by 1000 to convert to kilowatt (kW) and then multiply by time in hours...
Cyclic voltammetry can be used to measure two parameters, which can together can be used to determine if a reaction is reversibly for a given scan rate. These are: The difference in the potential difference between the anodic peak current and the cathodic peak current The height of the anodic...
Aluminum alloys play an important role in circular metallurgy due to their good recyclability and 95% energy gain when made from scrap. Their low density and high strength translate linearly to lower greenhouse gas emissions in transportation, and their
To determine which neurophysiological processes and functional neuroanatomical structures are associated with these counterintuitive effects, we examined event-related synchronization and desynchronization processes27 in theta and alpha-band activity and performed beamforming analyses. Of note, the investigated ...
When you place a copper electrode and a zinc electrode in a container of mud (it has to be wet), the two metals start reacting, because zinc tends to lose electrons more easily then copper and because dirt contains ions. Wetting the dirt turns it into a true electrolyte "solution." So...
During this reaction, the reddish-orange dichromate ion changes color to the green chromium ion when it reacts with the alcohol; the degree of the color change is directly related to the level of alcohol in the expelled air. To determine the amount of alcohol in that air, the reacted mixt...
What is titration? What equation can we use for titration problems? How to determine when to reach the equivalent point?Analytical Chemistry:Analytical chemistry is one of the major branches of chemistry which is greatly concerned with instrumentation, samplin...
To determine the optimal τ, we studied the τ dependence of the co-ion desorption and counterion adsorption times, which are the times needed by the co-ion and counterion densities to reach their equilibrium values corresponding to the final applied voltage (these times are not the same41 and...
The emf of the driver cell in the potentiometer experiment should be greater than the emf of the cell to be determined. Why? View Solution In an experment to determine the emf of an unknown cell, its emf is conparaed with a standard cell of known emf epsi_(1)=1.12V . The balanc po...
