Explain why sodium hydroxide cannot be used as a primary or secondary standard - i.e. why the molarity of a sodium hydroxide solution cannot be determined by simply weighing out a sample of solid NaOH, dissolving it in a known amount of water, and calculating its molarity based on the molar mass of MaOH and the overall volume of solution.
Calculate the standard enthalpy of the reaction, \Delta {{H}^\circ}_{\rm rxn}, for the thermite reaction: \rm 2Al(s) + Fe_2O_3(s) \rightarrow 2Fe(s) + Al_2O_3(s)
The diluted solution is then placed in a spray bottle for application on the desired surfaces. How many moles of luminol are present in 2.00 L of the diluted spray
describe the hybrid orbitals uses by the central atom and the types of bonds formed in
A compound of a transition metal and iodine is 65.1% metal by mass. How many grams of iodine is present in 859 g of this compound?
What is the molarity of C6H12O6 in an aqueous solution that is prepared by dissolving a 20.95 g sample of impure C6H12O6 in water to make 1,450 mL of solution. Assume that the sample is 93% C6H12O6 by mass. Enter your answer in mol/L, accurate to ..
if i have 0.621 mole of potassium chlorate that decomposes by heat, what is the amount of the oxygen in moles?
The reaction 2NOCl(g) → 2NO(g) + Cl2 (g) has an activation energy of 100.0 kJ/mol and a rate constant at 400.0 K of 8.5 x 10-6 mol-1 L s-1. Determine the rate constant at 450 K.
