The combustion of magnesium creates so much energy so quickly that it is hard to measure its enthalpy directly using a simple calorimeter. however, you will break this reaction down into other intermediate reactions whose enthalpies you can – and will – measure. what broad question are you answering by doing this experiment?

According to the tide table below what time of day will the highest tide occur? (2 pt) the highest tide will occur at

Abeaker with 2.00×102 ml of an acetic acid buffer with a ph of 5.000 is sitting on a benchtop. the total molarity of acid and conjugate base in this buffer is 0.100 m. a student adds 4.70 ml of a 0.360 m hcl solution to the beaker. how much will the ph change? the pka of acetic acid is 4.740.

How does a catalyst increase the speed of a reaction? a. the catalyst eliminates the activated complex stage, allowing products to form immediately. b. the catalyst lowers the energy level of the reactants, making it easier for them to react. c. the catalyst makes it easier for the activated complex to form, lowering the activation energy. d. the catalyst raises the energy level of the products, making the reaction finish sooner. reset next
