WebFor the enthalpy change, write an equation representing this change including its state symbols. For the formation of propanone, one mol of the propanone should form the main equation. 3C(s) + 3H 2 (g) + 0.5O 2 (g) → CH 3 COCH 3 (l) The reactants in this equation C(s) and H 2 (g)can be burned to produce CO2(g) and H2O(l). WebNext, we do the same thing for the bond enthalpies of the bonds that are formed. So the bond enthalpy for our carbon-oxygen double bond is 799 kilojoules per mole, and we multiply that by four. The bonds enthalpy for an oxygen hydrogen single bond is 463 kilojoules per mole, and we multiply that by six. When we add these together, we get 5,974.
WebApr 14, 2024 · Hsp70.1 has a dual function as a chaperone protein and lysosomal stabilizer. In 2009, we reported that calpain-mediated cleavage of carbonylated Hsp70.1 causes neuronal death by inducing lysosomal rupture in the hippocampal CA1 neurons of monkeys after transient brain ischemia. Recently, we also reported that consecutive injections of … WebState the meaning of the term mean bond enthalpy for the H−O bond. (2 marks) The enthalpy (change) to break 1 mol of H—O / bonds; Averaged over a range of compounds. Explain why CF4 has a bond angle of 109.5°.
