Determining the Enthalpy of a Chemical Reaction All chemical reactions involve an exchange of heat energy; therefore‚ it is tempting to plan to follow a reaction by measuring the enthalpy change (∆H). However‚ it is often not possible to directly measure the heat energy change of the reactants and products (the system). We can measure the heat change that occurs in the surroundings by monitoring temperature changes. If we conduct a reaction between two substances in aqueous solution‚ then the

From the graph I can clearly see that Distilled water has a much larger concentration of water then the cell sap in the potato tissue. I can make this conclusion because the results show a big increase in weight of the potato piece. Meaning that water has moved from outside the potato into the potato due to Osmosis‚ proving that the distilled water had a higher concentration of water‚ as water moves from a high concentration to a low concentration. I can also see that the glucose

Will a dare go sour and come back to haunt them? The author‚ Lenord Ross‚ gives this story a title that puts a chill in your spine‚ "Cemetery Path". That tells you what the story’s about.

Marcella Santana Hanna Gray English 121 27 February 2013 Path to Citizenship The Heritage Foundations‚ Tim Kane‚ Ph.D.‚ writes “America’s exceptional status as a ‘nation of immigrants’ is being challenged by globalization. The biggest challenge for policy makers is to distinguish illusory immigration from real problem. The supported approach from recent years ‘a policy of benign neglect’ is no longer an option.” Members from the Senate and House of Representatives both recognize this and should

DETERMINATION OF FRUIT ACIDS BY TITRATION AND CALCULATION OF THE SUGAR/ACID RATIO It is the sugar/acid ratio which contributes towards giving many fruits their characteristic flavour and so is an indicator of commercial and organoleptic ripeness. At the beginning of the ripening process the sugar/acid ratio is low‚ because of low sugar content and high fruit acid content‚ this makes the fruit taste sour. During the ripening process the fruit acids are degraded‚ the sugar content increases and

Determination of Equilibrium Constants Introduction Bromothymol blue is an indicator for many acid-base titrations. When adding different solutions within the indicator it is to react and change colors‚ in this experiment the different colors were blue‚ green‚ and yellow. In the following experiment‚ obtaining the absorbance levels for each one makes it possible to calculate the equilibrium constant. Materials and Methods For this specific experiment there are a few materials that are crucial
