If the observed wind speed by an anemometer is 5 m/s, what is the wind speed at 100 m height if the value of the index p = 0.15?
The pH at the first stoichiometric point was 5.19 and at the second stoichiometric point was 8.00. Calculate the three Ka values for the acid.
Give the chemical equation for the reaction that occurs in (B) to reach equilibrium.
indicate whether aqueous solutions of each of the following solutes will contain only ions, only molecules, or mostly molecules and a few ions: a) NH4Cl, a strong electrolyte. b)ethanol, CH3-CH2-OH, a nonelectrolyte. c)HCN, hydrocyanic acid, a wea..
Gaseous NOBr is placed in a closed container at -180 oC, where it partially decomposes to NO and Br2: 2 NOBr(g) 2 NO(g) + 1 Br2(g) At equilibrium it is found that p(NOBr) = 0.008230 atm, p(NO) = 0.004080 atm, and p(Br2) = 0.004130 atm.
