Which of the following species is present in the greatest concentration in a 0.100 M H2SO4 solution in H2O?
A. H3O+B. HSO4-C. H2SO4D. All species are in equilibrium and therefore have the same concentration.E. SO42-

The water level in a graduated cylinder initially at 225 rises to 278 after a piece of lead is submerged. What is the mass in grams of the lead?
Calculate how the amount of AgCl(s )will change when the equilibrium is disturbed by Adding AgNO 3
Quicklime (CaO) is produced by thermal decomposition of calcium carbonate(CaCO3). Calculate the volume of CO2 at STP produced form the decomposition of 146 g CaCO3 by the reaction: CaCO3(s) -> CaO(s) + CO2(g)
Concentration : Dilution Problem, A student placed 18.5g of glucose (C6H12O6) in a volumetric flask, added enough water to dissolve the glucose by swirling, then carefully added additional water until the 100.-mL mark on the neck of the flask was ..
Determine all of the term symbols for the following free atoms. Choose the ground state term in each case B N Mg V As Lu
HNO3 has 2 dissociating ions whereas Al(NO3)3 has 4, which should result in a higher conductance value. Would this have something to do with aluminum nitrate being paired with water as a solid?
Question about Half life problem, We are performing an experiment using half-life =4.5 x 10^3 days labeled phenylalanine in which the five atomic hydrogens are labeled.To perform the experiment
Show that the species Co^3+ (aq) will spontaneously decompose to CoO2 (s) and Co^2+ (aq) at PH 0 the question need to solve for the potential at both pH of 0 and pH of 5 to prove that at pH of 0 the cobalt will decompose spontaneously, but at pH o..
