Place the subsequent molecules and ions in order of increasing bond angle about the central atom as well as explain your decision citing evidence from Part B.
NO3-, CO2, NO2-, CH2Cl2, NH3, H2S
Write the net ionic equation for this reaction. (Include states-of-matter under the given conditions in your answer. Use the lowest possible whole number coefficients.)
A 36.3 mL aliquot of 0.0529 M (aq) is to be titrated with 0.0411 M NaOH (aq). What volume (mL) of base will it take to reach the equivalence point?

the enthalpy change is 25.8 KJ. How many grams of H2 gas are produced? and d: How many KJ of heat are released when 50.9 g of CO gas reacts completely with H2 to form CH3 OH at constant pressure?
Hexane has a vapor pressure of 100 torr at 15.8 C and 400 torr at 49.6 C. What is its deltaHvap
The vapor pressure of a beaker of dilute aqueous solution of sucrose at 25 degree C is 3.111 kPa. Find the activity of water in this sucrose solution, given that the vapor pressure of pure water at 25 degree C is 3.167 kPa
the standard molar enthalpy of vaporization for water is 40.79 kjmol. what mass of steam is required to release 500. kj
Suppose it was found that in an equilibrium mixture of these gases the partial pressure of NH3(g) is 24.9 atm and the partial pressure of N2 is 6.68 atm. What is the partial pressure of H2(g)?

The molar solubility of AgBr in water is 7.31x10^-7 mol dm^-3 at 25C. What is the standard potential of the cell Ag(s)/AgBr(aq)/AgBr(s)/Ag(s) at that temperature
the carbon-carbon bonds would be alternately long and short. However, to consider the structures as resonance contributors (or to connect them by a double-headed arrow) violates a basic principle of resonance theory.
Explain which have a single nonbonding pair of electrons around the central atom. Define which have two nonbonding pairs of electrons around the central atom
