Analyze the reaction to determine whether the reaction is exothermic or endothermic. Explain your reasoning. A graph of time on the horizontal axis versus potential energy on the vertical axis for upper C upper H subscript 4 plus 2 upper O subscript 2 right arrow 2 upper H subscript 2 upper O plus upper C upper O subscript 2 plus 891 kilojoules. A line starts high on the vertical axis and runs parallel to the horizontal axis; this segment is labeled upper C upper H subscript 4 plus upper O subscript 2; the line rises, peaks, and falls sharply to near and parallel the horizontal axis. The parallel segment is labeled upper C upper O subscript 2 plus upper H subscript 2 upper O.

Calculate: select the worksheet tab. this tab you calculate the analyte concentration. fill in the first set of boxes ("moles h2so4" and "moles naoh") based on the coefficients in the balanced equation. (if there is no coefficient, the value is 1.) record the appropriate volumes in the "ml naoh" and "ml h2so4" boxes. record the concentration of the titrant in the m naoh box. click calculate. what is the concentration listed

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
