What safety precautions and aspects of WHMIS should be considered during the facilitation of neutralizing acid spills? And what precautions should be taken when handling the chemicals involved?
If I have 100.0ml of 0.350M lactic acid already, how many grams of sodium lactate (molar mass=112.06g/mol) will I need to add to this solution to make the preceding buffer
Although the viscosity varies over a factor of more than two in the series from hexane to nonane, the surface tension at at 25 degrees Celsius increases by only about 20% in the same series. How do you account for this
what is the molar solubility of caf2 in 0.10 m naf solution at 25°c? the ksp for caf2 is 1.5 x 10^-10
What is cystic fibrosis? How can cystic fibrosis lead to malabsorption and diabetes mellitus? How can cystic fibrosis lead to cirrhosis in the liver?
The rate constants of some reactions double with every 10 degree rise in temperature. Assume that a reaction takes place at 350 K and 360 K. What must the activation energy be for the rate constant to double as described
The half-life of a reaction, is the time it takes for the reactant concentration to decrease by half. For example, after one half-life the concentration falls from the initial concentration to, after a second half-life to, after a third half-life ..
addition of excess NH3 to this acidic solution produces only a blue solution. Which group III ions are present, which are absent and which are in doubt? How would you remove all doubt?
Explain what is the intact compound equation as well as the net ionic equation for the neutralization of aqueous hydrofluoric acid by aqueous calcium hudroxide
The isotope, carbon-14, is a very interesting isotope to study because of how ubiquitous carbon is in living organisms. However, isolating 14C from 14N can be very challenging.
Provide a method for seperating the mixtures of the compounds, dissolved in a solvent diethyl ether. In each case one of the components will be neutral compound. Give your answer in the form of flow chart.
Calculate the pH during the titration of 40 mL of 0.1M HCL with 0.1M NaOH solution after the following additions of base:
A solution contains .45M hydroflouric acid (HF, KA - 6.8*10^-4). Determine the degree of ionization and pH of the solution.
