By using appropriate thermochemical data from Appendix C (heats of formation), calculate the average bond enthalpies in the liquid state for the following bonds a) Br---Br from Br2 (l)b) C--Cl from CCl4 (l)c) O--O from H2O2 (l) assuming that the O--H bond enthalpy is the same as in the gas phase. d) what can you conclude about the process of breaking bonds in the liquid as compared to the gas phase? Explain the difference in the heat of formation values between the two phases

If 4.00 mol of calcium carbide (CaC2) reacts with an excess of water, how many moles of acetylene (C2H2), a gas used in welding, will be produced.
The component of structure responsible for holding the 4 chains of hemoglobin together is a. primary
A solution is made up using equal volumes of 2.0 M acetic acid (Ka= 1.8 x 10 to the power of negative 5) and 0.00050 M HCl.
A test solution contained 2 mL of 0.10 M Ag+. A silver strip was dipped into the test solution, and a cell potential of 0.0592 V was measured against an Ag/Ag+(1.0M) reference half-cell.
Why do we measure the volume of the flask with water rather than using the volume listed on the side?
