1. Based on the Le Chatelier's Principle,
a) Define what will happen to the equilibrium when some outside forces have been applied to the reaction? Give two examples of these forces.
2. Define the possible shift in equilibrium positions for Copper (II) with water and iodide ion.
Point to what will happen to the copper ion for each step of chemical addition.
Determine the limiting reagent
Important information about Molar concentrations, Calculate the molar concentrations, I-, disulfur octaoxide, disulfur trioxide.
The following oxidation/reduction reaction of copper and tin has an equilibrium constant equal to 1.48 at 300 Kelvin. At this temperature the equilibrium concentrations are measured to be [Sn^2+]=0.124 M, [Cu+]=0.148 M and [Sn^4+]=0.176.
A gas vessel is attached to an openend manometer containing a nonvolatile liquid of density 0.791g/mL. The difference in heights of the liquid in the two sides of the manometer is 43.4 cm when the atmospheric pressure is 755 mmHg.
When atomic absorption spectrophotometer had been allowed to adequately equilibrate, a blank determination of absorbance gave the following results.
How can you estimate the pH range of an indicator's color change. why do some indicators have two separate pH ranges.
Find out the formula of the gas produced if Na 3 P(s) sodium phosphide, is reacted with H 2 O
A particular first-order reaction has a rate constant of 1.35x10^2 at 20 degrees C . What is the magnitude of k at 75 degrees C if Ea =85.6Kj/mol?
A mixture of He, Ar and Xe has a total pressure of 2.00atm. The partial pressure of He is 0.450atm, as well as the partial pressure of Ar is 0.350atm. Explain what is the partial pressure of Xe
A 1.4639g sample of limestone was analyzed for Fe, Ca, and Mg. The iron was determined as Fe2O3, yielding 0.0357g. Calcium was isolated as CaSO4, yielding a precipitate of 1.4058g, and Mg was isolated as 0.0672g of Mg2P2O7.
According to NMR spectra rules, a carbon that is more substituted is more deshielded. For some reason I cannot understand this, because in my mind I see it has more shielding since there is more electron density around it. Please explain in detail..
