The balance used to measure the mass of the metal reads low (for example, it reads 19.4 g instead of an actual 19.7 g). How will this error, due to miscalculation of the balance, affect the reported specific heat value for the metal? Explain.
Write the net redox reaction.
what mass of KNO3 will crystalize out of solution if exactly 9.0x10^2g of its saturated solution at 75c is cooled to 25c
If a buffer is made up to be 1.0M in acetic acid and 1.0 M in sodium acetate, predict how much acid will be required to change the pH of 100mL of the buffer by 0.1 pH units.
Hydrogenation reactions are used to add hydrogen across double bonds in hydrocarbons and other organic compounds. Use average bond energies to calculate DELTA Hrxn for the following hydrogenation reaction
A balloon is filled to a volume of 9.00 multiplied by 102 mL at a temperature of 18.0°C. The balloon is then cooled at constant pressure to a temperature of 1.00 multiplied by 102 K. What is the final volume of the balloon?
The first ionization energy of Ca is 590 kJ/mol and its second ionization energy is 1145 kJ/mol. The heat of sublimation of Ca is 178 kJ/mol. The bond energy of Br2 is 193 kJ/mol, the heat of vaporization of Br2(l) is 31 kJ/mol , and the electron ..

A buffer solution is prepared by adding 32.8 grams of sodium acetate, NaC2H3O2 to 1.00 L of 0.500 M acetic acid, CH3CO2H. Ka = 1.8 x 10-5 for acetic acid.
isopentyl alcohol, how many grams of isopentyl acetate could you theoretically produce assuming only a 65% attainable yield?
An element crystallizes in a face-centered cubic lattice. The edge of the unit cell is 392 pm, and the density of the crystal is 21.45 g/cm3. Calculate the atomic weight of the element (in g/mol)
What significant difference would be expected between a titration curve for H3PO4 (triprotic acid) and a mixture
A similar question was asked before, but the formatting of the answer made it unreadable. So, I am asking it again. I have a thermodynamic system with three states in the canonical ensemble
