Write out a detailed procedure for determining the enthalpy ofreaction between citric acid (H3Cit) and sodiumhydroxide (NaOH). Note that the neutralization reaction is:
H3Cit + 3 NaOH -> Na3Cit + 3H2O
Besure to calculate what volume of each 0.50 M solution shouldbe mixed to give a total volume of 50.0 mL and the reactants in thecorrect stoichiometry.
how many millileters of a 0.225 M HCL solution are needed to neutralize 259 mL of a 0.0309 M Ba(OH)2 solution.
Write the balanced equation for the neutralization reaction between HI and Ba(OH)2 in aqueous solution. Include physical states.
An ice cube at 0 degrees C with a mass of 115 g is added to H2O in a beaker that has a temperature of 64.0 degrees C. if the final temperature of the mixture is 24.0 degrees C, what was the initial mass of the warm water
Carbonic acid is an intermediate step in the transport of CO2out of body. If the pH of blood is 7.4, what percent is carbonic
Write the total and net ionic equations for the reaction of BaSO4 dissociation, and calculate the trial Ksp for the product formed, when 40 mL of 0.1 M Ba(CH3COO)2 reacts with 60 mL 0.6 M MgSO4 and decide whether a ppt will form
Calculate the solubility (in M units) of ammonia gas in water at 298 K and a partial pressure of 7.50bar . The Henry's law constant for ammonia gas at 298 K is 58.0 M atm and 1 bar = 0.9869 atm.
air expands from 500 psia 5000f to 15 psia in a process that is reversible adiabatic. if the atmospheric pressure is
Calculate the [Zn2+] in a solution of ZnC2O4 held at a pH of 3.00. Remember C2O4^2- is a weak base so you must consider other equilibria.
A certain atom has a doubly degenerate ground level pair and an upper level of four degenerate states at 450 cm?1 above the ground level. In an atomic beam study of the atoms it was observed that 30 per cent of the atoms were in the upper level
when 16.8 j was added as heat to a particular ideal gas the volume of the gas changed from 42 cm3 to 87 cm3 while the
Two acid-base reactions are given below. Of the three reaction arrows presented in each reaction, select the arrow (via the multiple choice circle before it) that best indicates the acid-base equilibrium position
Suppose you have a sample which should melt at 100-101 degree C. You place 0.015 grams in a capillary tube in an oil bath at 101 degree C. If the heat of fussion for the sample is 50 cal/gram
