Suppose a similar experiment had been done using 1.0 M H3PO4 solution as the acid. What would be the expected stoichiometric ratio, mol H3PO4 / mol NaOH, at the intersection of the ascending and descending portions of the graph for such an experiment?
Determine the molecular geometry, or shape, of ClO2 a. octahedral b. tetrahedral c. trigonal bipyramidal d. trigonal planar e. t-shaped f. bent
Calculate how many grams of ATP must be produced to walk a mile. ATP synthesis is coupled to the oxidation of glucose (?Go' = -686 kcal/mol). How many grams of glucose are actually metabolized to produce this amount of ATP?
Acetylene gas (C2H2) is produced as a result of the reaction CaC2+2H2O-->C2H2+Ca(OH)2 If 16g of CaC2 are consumed in this reaction, how much H2O is needed? answer in units of mol.
What types of intermolecular forces would you expect to exist among molecules of 1-butanol? (Select all that apply.)
Rather than weigh the sample on a balance a chemist wants to dispense the liquid using a pipette. What volume (in mL) should she measure out?
A chemical plant produces an ammonia-rich waste gas that cannot be released as-is into the environment. One method to reduce the ammonia concentration in the waste gas is to bubble the waste gas through a liquid solvent.
Cesium-131 is a short lived radioisotope (t1/2= 9.7 days) used to treat prostate cancer. How much theraputic strength does a Cesium-131 source lose over 60 days? Express your answer as a percent of the strength the source had at the begining of th..
Consider barium hydroxide, Ba(OH)2, a white powdery substance. Student A prepares a solution of Ba(OH)2 by dissolving 4.23 g of Ba(OH)2 in enough water to make 455 ml of solution.
In the reaction below, 4.86 atm each of H2 and Cl2 were placed into a 1.00 L flask and allowed to react: H2(g) + Cl2(g) 2 HCl(g) Given that Kc = 89.9, calculate the equilibrium pressure of HCl.
how is the rate of consumption of O2 related to the rate of consumption of NH3 in the reaction 4NH3 + 5O2 -->4NO +6H2O?
One way to approach the problem is to imagine the reaction proceeds to equilibrium by first going 100% to completion and then backing up a little
The total mass of the car plus sand is 85,000 . The hopper door is not fully closed so sand leaks out the bottom. After 18.0 minutes, 1.34×104 of sand has leaked out. Then what is the speed of the railroad car?
