Write a chemical equation for HF(aq) showing how it is an acid or a base according to the Arrhenius definition? Write a chemical equation for Ba(OH)2(aq) showing how it is an acid or a base according to the Arrhenius definition? Write a chemical equation for HC2H3O2(aq) showing how it is an acid or a base according to the Arrhenius definition? Really need some help with these. I understand most of it but can't come up with the right answers apparently.
The activation energy of a certain reaction is 65.2 kj/molHow many times faster will the reaction occur at 51 degrees C than at 0
Use the van der Waals equation of state to plot the compressibility factor, Z, against P for methane at 180K and 250K. Hint: calculate Z as a function of V/n and P as a function of V/n, and then plot Z Vs. P.
hydrogen and 6.8 * 10^-4 mol of oxygen. How much water can be produced if the gases react?
What is the dry basis concentration of carbon dioxide using the concentration data given below. Conc. CO2 (Wet) = 15.4% and Conc. H2O = 4.3%
What is the maximum number of distinct spectral lines (lines of different wavelengths) that can be observed from this system? Calculate the wavelength of each of these lines and sketch the observed spectrum
Explain why alcohols such as ethanol and propanol are soluble in water, butanol is moderately soluble and pentanol is slightly soluble
Do these lambda maxs indicate an increase or a decrease in the energy of the light absorbed as the number of EN ligands bound to Cu(II) increases
The first-order decomposition of phosphene to phosphorus and hydrogen 4PH3(g) → P4(g) + 6H2(g)
Calculate the pressure and the temperature of the compressed gas. In a diesel engine the compression ratios are typically much higher; redo the same calculation for the compression ratio of 20:1.
A 100.0 mL sample of 0.10 M NH3 is titrated with 0.10 M HNO3. Determine the pH of the solution after the addition of 50.0 mL of HNO3. The Kb of NH3 is 1.8 × 10-5.
How could you use a conductometric titration to determine the molarity of either reacting solutions, assuming you knew the concentration of one
The specific heat of liquid water is 4.184 J/g. degree C. Calculate the energy required to heat 10.0 g of water from 26.5 degree C to 83.7 degree C.
