1. Cut wo squares of black paper or suminio foi 2 Dewan Sahnpe on one of the squares. See the game
miongside for details. Cat the shape out of the paper ou
3. Using paper clips attach the paper or foil with the cat
auts on the upper surface of the leaf and the other
piece on the lover surface of the leafas shown. The leaf
must be in direct sunlight.
4. Leave the leaf covered for 24 hours
5. Before carrying out experiment A, to investigate if the
lear has produced starch, make sure that the leaf has
had at least two hours of sunlight
6. Pick the leaf. Remove the paper or foil
7. Carry out Experiment A.
8. Recond your results by drawing and labelling the leaves Which part of the leaf was the experiment ​

Problem #3 (ch. 1, problem 15)the ideal gas law provides one way to estimate the pressure exerted by a gas on a container. the law isí‘ťí‘ť=푛푛푛푛푛푛푉푉more accurate estimates can be made with the van der waals equationí‘ťí‘ť=푛푛푛푛푛푛푉푉â’푛푛푟푟â’푞푞푛푛2푉푉2where the term nb is a correction for the volume of the molecules and the term an2/v2is a correction for molecular attractions. the values of a and b depend on the type of gas. the gas constant is r, the absolutetemperature is t, the gas volume is v, and the number of moles of gas molecules is indicated by n. if n = 1 mol of an ideal gas were confined to a volume of v = 22.41 l at a temperature of 0â°c (273.2k), it would exert a pressure of 1 atm. in these units, r = 0.0826.for chlorine gas (cl2), a = 6.49 and b = 0.0562. compare the pressure estimates given by the ideal gas law and the van der waals equation for 1 mol of cl2 in 22.41 l at 273.2 k. what is the main cause of the difference in the two pressure estimates, the molecular volume or the molecular attractions?

Based on the equation and the information in the table, what is the enthalpy of the reaction?
