A chemistry graduate student is studying the rate of this reaction:
2SO3 = 2SO2 + O2
he fills the reaction vessel with SO3 and measures the concentration as the reaction proceeds
Time in seconds [SO3 ]
0 0.0900 M
0.10 0.0406 M
0.20 0.0262 M
0.30 0.0194 M
0.40 0.0153 M
Use the data to calculate the value of the rate constant k. Round your answer to two sig figures
How many grams of sodium hydroxide are needed to react completely with 50.1 mL of 0.145 MCoCl2 solution?
calculate the pH you would expect to measure if 15.0mL of 0.5M acetic acid were mixed with 25.0mL of 0.5M sodium acetate
With natural selection, how can the use of antibiotics result in resistant bacteria?
To an aqueous sodium chloride solutions we add another 100 g of NaCl, and all of the added NaCl dissolves. This implies that the initial sodium chloride solution was:
Problem- Half of a mole (.5mol) of neon, an ideal gas, is isothermally and reversibly compressed at 305 K from an initial pressure and volume of 2.5 atm and 5.0 L to a final pressure and volume of 12.5 atm and 1.0 L. What are q and w for the compr..
Since heat is an extensive property, the amount of heat that is produced depends on the amount of reactants utilized in the reaction. If you have more reactant then you will have more heat. Just think of a big fire cracker versus a small fire crac..
What type of crystal (atomic, molecular, ionic, metallic, or network covalent) are crystals of each of the following:
Consider the reaction at 25C 2NO2 --> 2NO + O2 The overall rxn rate = k[NO2]2. The rate constant, k = 1.4 × 10?10 M?1 s?1. If 3.8 moles of NO2 are initially present in a sealed 1.00 liter vessel at 25 C, what is the half-life of the reaction
The hydrated radii of sodium, hydronium, acetate, and nitrate ions are 4.5, 9.0, 3.5, and 3.0 °A, respectively what is the strength of the solution? calculate the activity coeffiecents of each speicies.
Why was anhydrous not wet diehtyl ether used in the preparation and reaction of the grignard reagent
The pH of a certain solution is 4.5. What is the concentration of H+(aq) ions in the solution. A) 3.16 x 10^-5 M B) 3.16 x 10^4 M
