Calculate the enthalpy change (energy needed) to convert 18 grams of ice at 0 Celcius to water vapor(steam) at 100 Celcius under constant pressure. The specific heat is 4.18 J/grams*Kelvin, for water deltaheat of fusion is 6.01k/mole and deltaheat of vapor is 40.67kj/mole.
Consider the following reaction: SO2Cl2 (g) SO2 (g) + Cl2 (g). K = 2.99*10^-7 at 227 degrees celsius. If a reaction mixture initially contains 0.159 , what is the equilibrium concentration.
A line in the Paschen series of hydrogen has a wavelength of 1280nm. From what state electron originate ?
A solution that is made by combining 125mL of 0.050 M hydrofluoric acid with 50.0mL of 0.10 M sodium fluoride.
A buffer is 0.282 M C6H5COOH (aq) and 0.282 M NA(C6H5COO)(aq). Calculate the pH after the addition of 0.150 moles of nitric acid to 1.0 L of the buffer.
Of the following compounds, which would be considered ionic bonds and which would be considered covalent bonds, and why
Fructose contains only C,H, and O. 17.1g of carbon dioxide gas and 7.26 g of water vapor were produced when 12.1 g of solid fructose were combusted with excess of oxygen gas.
A 32.0-g sample of water at 290. K is mixed with 51.0 g water at 340. K. Calculate the final temperature of the mixture assuming no heat loss to the surroundings.
Derive an expression for the number of molecules with a speed (c) greater than some specified speed (c'). Recall that the number of molecules having speed in a certain range is the integral under the Maxwell-Boltzmann speed distribution curve ..
What [OH-] is necessary to start precipitation of Cu(OH)2 in a 0.0014 M copper(II) chloride solution?
the hybridization of Carbon in this molecule? b) What would be its molecular shape? and c) What is the bond angle around the C atom?
Our book shows a radioactive decay series in which a sample that starts out as U-238 eventually winds up becoming non-radioactive Pb-206. The half life for this process is extremely long, being 4.51 x 10^9 years. Consider a radioactive mineral sam..
