Draw two equivalent resonance forms for nitric acid and three for nitrate ion. Rank the three types of nitrogen-oxygen bonds in order of length.
Based on your understanding of the relationship between acid/base behavior and chemical structure, match the Ka with each acid. Then calculate the pKa which corresponds to each value.
The rate at which equilibrium is established depends on the rate at which collisions occur. Estimate the number of collisions/(m3 s) among all molecules of air at 1.0 atm pressure and 0 C.
write the chem equation for the reaction which occurs when solutions of potassium sulfide and iron (II) chloride are mixed.
A compound contains 10.13% C, and 89.87% Cl (by mass). Determine both the empirical formula and the molecular formula of the compound given that the molar mass is 236g/mol
How many grams of CaCl2 are needed to make 364.8 g of a solution that is 37.5% (m/m) calcium chloride in water? (Note that m/m has the same meaning as w/w.)
A 1.994g sample of ethanol, CH3CH2OH is combusted in a bomb calorimeter. The temperature of the calorimeter increases by 10.91. If the heat capacity of the bomb is 615.5j/k and it contains 1.150kg of water, what is the enthalpy chnge per mol of et..
When 0.0200 mol gaseous NH3 and 0.0180 mol gaseous O2 are placed in a 1.00 L container at a certain temperature, the N2 concentration at equilibrium is 2.20Ã-10-3 M. Calculate Keq for the reaction at this temperature.
Assuming that N2 obeys the Van der Waal's equation, determine the Boyle temperature of 1 mol of N2 and determine the percent error in the answer knowing that the experimental value of the Boyle temperature
Data for the decomposition of hydrogen peroxide at some set temperature T is include below. The rate law depends only on the concentration of H2O2.
What is the structure of the alkane? The reaction of lithium di-sec-butylcuprate with isopenyl bromide yields?
Calculate the heat required to convert 58.0 g of C2Cl3F3 from a liquid at 14.90 degrees C to a gas at 90.75 degrees C.
Identify the type of reaction for each of the following as combination, decomposition, single replacement, double replacement, or combustion: a) a compound breaks apart into its elements
