Predict what you would expect to observe when each of the following substances is mixed with NaI/acetone. Would you expect a difference in their relative rates of reaction
Determine how many grams of copper sulphate are there in 219 grams of an aqeous solution that is 20.2% by weight of copper sulphate?
Calculate the molality H3PO4 in the solution and Water is the solvent and the molarity of H3PO4 in the solution and the number of ml of the 85% H3PO4 that is required to make 800 ml of 2.00 M H3PO4?
Assume ^35^Cl_2_ is a harmonic oscillator( it is slightly anharmonic). If K=329 N/m compute the zero-point energy for this molecule. ^35^Cl= 34.9688g/mol.
After equilibrium is reached, (X)=.55 M. Calculate the Keq (Kc) for this reaction. show full steps please for rating
Consider the dissolution of magnesium (s) in an aqueous hydrochloric acid solution. What minimum amount of 1.85 M hydrochloric acid is nessecary to produce 28.5 L of hydrogen at STP
The endpoint in the titration is "overshot" A. is the reported molar concentration of the hydrochloric acid solution too high or too low. B. As a result of this poor titration technique, is the reported number of moles of B4O5(OH)4^2 would be too ..
