5. Acetic acid has a melting point of 16.6°C and a boiling boing of 117.9°C. Sketch a heating curve showing the phase changes of acetic acid. Clearly label all 7 parts like we did in our notes.

When hydrochloric acid reacts with potassium hydroxide solution, the following reaction occurs. hcl (aq) + koh (aq) h2o (l) + kcl (aq) the reaction gives off heat energy, so it is an reaction.

Which element has the lowest electronegativity? calcium(ca) gallium(ga) selenium(se) bromine(br)

You form water vapor by mixing oxygen and hydrogen at 730°c in a 5.4-liter container. this is the equation for the reaction: o2(g) + 2h2(g) → 2h2o(g). the partial pressure of oxygen before the reaction is 122.3 kilopascals, and there is excess hydrogen. how many moles of water are formed?
