1. Using the average normality of the vinegar obtained in D (0.85 M vinegar), calculated the weight of acetic acid present in your vinegar sample.
2. Calculate the % of acetic acid in your vinegar sample.
Chemical-plant equipment costs rarely vary in proportion to size. In the simplest case, cost C varies with size S according to the allometric equation 18 Chemical Engineering Thermodynamics C = ?S?
The problem states that 4.36g of an unknown alkali metal hydroxide is dissolved into 100.0 ml of water. It is then titrated with 2.50 M HCl using an acid-base indicator. The equivalence point is 17.0 ml of HCl.
An aqueous solution of nitrous acid (HNO2) has a ?G= 19.1 kJ. What is the pH when [NO2-]=1.00 M, [HNO2]=1.00 M, and the ?G=0?
How could you make a dilute solution (ex. 0.5% (w/v) sucrose) more concentrated (without adding more sucrose)?
must be dissolved in 15.0g of camphor to lower its freezing point by 2 degrees celsius? constant k of camphor = 37.7 (*C x kg)/mol
Metabolix is an entrepreneurial firm that has invented the first 100% biodegradable plastic. This innovation has reduced the time of plastic decomposition
a 460 ml sample of oxygen o2 was collected by displacement of water at 24 ? c under a total barometric pressure of 1095
I need help describing an experiment where one could measure the value of the extinction coefficient of a solution with a concentration (c mol/L) of chlorophyll in water for a given wavelength.
Determine the activation energy for diffusing copper into gold if you know that the diffusion coefficient is 3.98 x 10-13 m2/s at 980 oC and the diffusion coefficient is 3.55 x 10-16 m2/s at 650oC.
Compound A is C4H9Cl and shows two 13C NMR resonances. Compound B is an isomer of compound A; it shows four 13C NMR resonances, and in the spin-coupled mode the resonance farthest downfield is a doublet. Identify compound A
