Table salt is comprised of sodium (symbol Na) and chlorine (symbol Cl) in a simple one to one ratio. It is written in chemical shorthand as NaCl. How would you go about finding approximately how much salt there is in our body?
An oligomeric protein has a molecular weight of 168000. A 420 mg sample was treated with an excess of 1-fluoro-2,4-dinitrobenzene (Sanger\'s reagent) until the reaction was complete
Excess Ag2CO3 is added to an 0.2 M K2CO3solution. Calculate the equilibrium concentration of Ag+ under these conditions.Ksp for Ag2CO3 is 8.1 x 10-12.
sample of anhydrous salt sodium sulfate Na2SO4 is allowed to absord water to form the decahydrate salt.
Propose structures for aromatic hydrocarbons that meet the following descriptions:
What precautions or what type of actions should the EH&S or FS professionals take when faced with a situation involving polychlorinated biphenyls (PCB's.)?
Write the balanced reaction and determine the mass of KNO3 that should be mixed with 6.1 g of sugar to produce optimally balanced rocket candy.
Calculate the pH at the equivalence point in titrating 0.120 M solutions of each of the following with 8.0* 10^-2 M NaOH
On the obtained mass-spectra you got in the expected parent-ion mass region two adjacent lines with almost the same abundance
The temperature after the reaction is 25.23 C. If the density of final solution is 1.02 g/mL, calculate q, if the specific heat of the solution can be assumed to be equivalent to that of water.
volume of methane gas is cooled from 298 K to 149 L. If the pressure remains constant, what is the final volume?
Compute the number of moles - As we know many volatile substances are present in Earth's atmosphere in trace amounts.
how many liters of NO gas can be produced at STP from 80.0 mL of a 4.00 M HNO3 solution and 10.0 g of Cu? 3Cu(s) + 8HNO3(aq) > 3Cu(NO3)2(aq) + 4H2O(l) + 2NO(g)
