1) Although the aluminum cylinder is a solid (and, therefore, is quite in-compressible), it actually contains quite a bit of empty space. Consider an aluminum atom to be a sphere with radius equal to 143 pm and calculate the volume actually occupied by the atoms in your aluminum cylinder (1 pm = 10^-12 m; V¬Sphere = 4/3?r¬^3
Considering the given equation KOH + CH 3 COOH ---> KCH 3 COO + H 2 O determine the volume of 0.157M solution Potassium hydroxide is essential to react with 0.385g of Acetic acid? express your answer in mL
Combustion analysis of naphthalene, a hydrocarbon used in mothballs, produced 8.80 g CO2 and 1.44 g H2O. Calculate the empirical formula for naphthalene?
Rate Law for Proposed Mechanism, Consider the reaction 2NO(g) + O2 ---> 2NO2 (g). The following mechanism has been proposed to explain the experimental rate law
using a sample of river water sample analyzed for total inorganic carbon ,The river pH= 7.1 and an inorganic C concentration of 6.97 mg C/L.c
Drag the flask and drop it on the lower half of the burette to connect them. Open the Data window and click on the flask. Click the Pushpin icon in the blue bar of the Data window to lock its display to the flask's contents.
Calculate concentrations of H30+ and the pH of each acidic solution. Since HCl is a monoprotic acid, the H30+ concentrations are equivalent to HCl. First do equation: (M con)(V con)=(M dil)(V dil)
How much energy would be absorbed or re- leased by the H2O in the process 30 grams H2O(g) at 100?C → 30 grams H2O(l) at 20?C.
The % of antifreeze should be raised to twenty five percent by draining some of the mixture and adding 100% antifreeze determine how much mixture should be drained?
The air track carts in the figure are sliding to the right at 1.0 meter per second. Find the speed of the carts.
What is the pH of a solution made by mixing 30.00 mL of 0.10 M acetic acid with 30.00 mL of 0.10 M KOH? Assume that the volumes of the solutions are additive. Ka = 1.8 × 10-5 for CH3CO2H.
calculate the heat released when 166g of water at 23 degrees celcius is converted to ice at negative 10 degrees celcius
A 1L flask is filled with 1.00 g of argon at 25 C . A sample of ethane vapor is added to the same flask until the total pressure is 1.20 atm. What is partial pressure of Argon and ethane in the flask?
