For each statement indicate which type of bonding is true/present: (Dispersion, dipole-dipole, or hydrogen bonding)
- the force between SO2 molecules
-the force that accounts for HF being a liquid while H2 & F2 are gases
-the only intermolecular force that exists in noble gases
-the attractive force between neighboring dipoles
-the force that arises because of the large differences in electronegativities in the N-H bonds
Calculate the uncertainty (in nm) in the position of an electron with the velocity of 2.00x103 m/s (the velocity is the same as in the preceding problem) and the uncertainty in the velocity is 1%. (2 significant figures are plenty).
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.
the solvent travel only half way up the chromatographic paper in the spot testing chromatogram.predict the effect of this procedural change on the solution of the cation in the standard mixture
To what volume should you dilute 95mL of a 12.0M H2SO4 solution to obtain 1.80M H2SO4 solution
How do we know the oxidation of camphor leads to a different product if they look/smell the same in the end as it did in the beginning?
The molecular weight of the protein is 3.4e4 grams per mole. What is the molar concentration of the protein?
odium carbonate (Na2CO3) can be produced by heating sodium bicarbonate (NaHCO3). A student heats 5.128 g sodium bicarbonate to completely decompose the sample to sodium carbonate.
The glass electrode used in commercial pH meters gives an electrical response proportional to the concentration of hydrogen ion. To convert these responses to a pH reading
The reaction is between furan and maleic anhydride. Using 0.19 g of furan and 0.24 g of maleic anhydride.
A total of 0.160 g of this subunit was dissolved in enough water to produce 2.00 mL of solution. At 28 C the osmotic pressure produced by the solution was 0.138atm. What is the molar mass of the protein?
What is the concentration of hydrogen ions in a solution containing 0.39 M HOCN(cyanic acid) and 0.726 M (NaOCN) (sodium shiu (ys6479) - Acid Base Buffers - dungan - (00533434) 3 cyanate).
Determine what volume of N 2 is released at 0.915atm of pressure and at the temperature of 25 degree celcius from a tank full of liquid N 2 ? (d=0.808g/mL)
