What is the basis for signal generation in this technique (i.e., describe how and what signal is measured by the scanning probe electronics)?
Use ΔG=ΔH-TΔS to calculate the standard free energy change, ΔG, at 25oC for the following reaction: CaCO3(s)-->CO2(g) + CaO(s)
A 2-kg mass of an ideal gas expands at a constant pressure of 172 kPa in a piston-cylinder system from a temperature of 32oC to a final temperature of 182oC. Determine Q, W, DeltaU and DeltaH.
the specific heat capacity of silver is 0.235 jgmiddotk. its melting point is 962degc and its heat of fusion is 11.3
Draw the skeletal structure of the indicated species. LDA is added to a solution containing phenyl propanoate. After this reaction has gone to completion, 3-pentanone is added.
Write down the dissociation reaction. (2) Estimate pH of a solution containing 0.6 g of acetic acid in 1 L of water. Molecular weight of acetic acid is 60 g/mol.
If 28mL of 7.0M Sulphuric acid(H2SO4) was spilled, then determine what is the minimum mass of NaHCO3 (Sodium bicarbonate or sodium hydrogen carbonate)
The Henderson-Hasselbalch equation is used to calculate the pH of a weak base, but not the pH of a weak acid.
alcohols are less volatile than ethers of the same molecular weight, but the two classes of compounds have approximately the same solubility in water because.
A 26.0-g sample of ice at -11.0°C is mixed with 123.0 g of water at 90.0°C. Calculate the final temperature of the mixture assuming no heat loss to the surroundings.
The reaction of combustion of ethanol is this: C2H5OH(g) +3O2(g) ---> 2CO2(g) + 3H2O (g) Los regalitos son ( g ) Lis 4 tienen(g ) A) calculate delta H of the reaction in kj/mol
The heat capacity of bomb calorimeters are determined by running a known, standard reaction. The combustion of 1.700 mmol of X caused the temperature of a bomb calorimter to rise from 23.650 oC to 26.350 oC.
When 0.069 mol of aluminum sulfate are dissolved in enough water to make 485 milliliters of solution, what is the molar concentration of aluminum ions?
