Estimate the temperature where Delta G = 0 for the following reaction (Given: Delta H=-176 and Delta S = -284.5 J/K NH3 + HCl --> NH4Cl

Use the data in the table to calculate the Delta G0 of the following reaction at 298k: Al2O3 ---> Delta G fusion -1582.3 HCl----> -131.2 AlCl3 -----628.8 H2O --- -237.1 The equation is Al2O3 + 6HCl ---> 2 AlCl3 + 3H2O products - reactants? [2(-628.8)+3(-2...

When 100.0 g of an unknown nonelectrolyte is dissolved in 500.0 g of benzene, C6H6, the solution boils at 82.9°C. Calculate the molecular weight (molar mass) of the unknown material. Kb for benzene is 2.53°C/m and the boiling point of pure benzene is 80.1...

The density of concentrated sulfuric acid is 1.84 g/mL. If this corresponds to 18 M, what is the molality of the solution? Molar mass= 98. 98 x 18 =1764g/L - 1.84 =1762.16/1000 = 1.76 kg 18/1.76=10.23 m But my only options are: a) 18 m b) 95.5 m c) 240 m...

Predict the bond angles in each of the following molecules: ^+^CH3 and Cl4Si My first guesses for 120 and 109.5 degrees, but not too sure

Give the molecular orbital description [e.g. sigma(sp3-sp3)] for each unique bond in the following structure. CH3NCHCCH I know how to draw the lewis structure and what a sigma and pi bond is, but I don't understand what the (sp3-sp3) part after the bond m...

Okay, I have some confusion on a lab question for chemistry. The question was if you were preforming a microscale extraction of a 0.2 g of benzoic acid/fluorenone mixture (About 6 mL of dichloromethane and 2 mL of NaOH were added through out this experime...

Yes, it is. So for like the triple bond in these structure, I know there's two pi bonds, and one sigma bond. But then for like the C---H bond off the triple bond it says the answer is a sigma bond (sp-s) So I don't know what it means by (sp-s) since by my...
