Lab activity 1: Effect of temperature‚ concentration‚ and pressure on equilibrium Introduction Our ongoing discussion has been on systems at dynamic equilibrium: for a reversible reaction‚ the rate of the forward reaction is equal to the rate of the reverse reaction. What happens if equilibrium is disturbed? In this lab activity‚ we are going to examine the effect of changing reaction conditions on the position of equilibrium. Part I: Effect of temperature We will consider the equilibrium

Aim: In this investigation I will be measuring the effects of temperature on the membrane permeability of beetroot. I will be measuring the amount of anthocyanin that will diffuse out of the beetroot. The way in which I will measure the anthocyanin is to check the light absorbency of the solution using a colorimeter. The higher the reading on colorimeter the more anthocyanin present in the solution To find out the permeability of the beetroot membrane I will firstly cut out cylinders of beetroot

The Mobius band is a one-sided surface that is constructed from a rectangle by holding one end fixed‚ rotating the opposite end through 180 degrees‚ and joining it to the first end. The Mobius band is much like the argument of whether or not we should implement drug tests on secondary school and pre-secondary school students because‚ like the Mobius band‚ it only has one side. Students ought to be drug tested for cigarettes‚ marijuana‚ and both licit and illicit drugs. Children are the future of

As the temperature increased‚ the enzyme activity also increased‚ however‚ only to an optimal level which was at temperature 32oC. Once the temperature was beyond the optimal level‚ the rate began to decline and this was represented by the concave curve on figure 5 and 7. This was because as the temperature increases‚ the frequency of collisions between the enzyme and the substrate also increased hence faster reaction rate. Whereas‚ the enzymes operated slowly at low temperature as there wasn’t sufficient

EXPLAIN THE CONTRIBUTION TO THE DEVELOPMENT AND EXPRESSION OF JUDAISM OF ONE SIGNIFICANT PERSON Rabbi Abraham Isaac Hacohen Kook‚ also known as Rav Kook‚ has made contributions to the development and expression of the Jewish religion that were of absolute importance. He was born on September 8‚ 1865‚ in Griva‚ Latvia and died on September 1‚ 1935 in Jerusalem. In his time‚ he was the first Ashkenazic Chief Rabbi‚ founder of Religious Zionism and a renowned Torah scholar. Rav Kook was responsible

And The Band Played On By Randy Shilts And the band played on is a true story published in 1987 that illustrates the AIDS epidemic. The AIDS outbreak started in this book around the 1970’s and is still around in today’s society. Randy Shilts wrote this book in order to show the many errors that occurred and killed while trying to find what this virus was and how it was spread. Many people during this time were affected by this virus especially in New York and San-Francisco‚ which is where most

When thinking of a band many think of it just being a collection of instruments. While that is true‚ it doesn’t fully encompass what a band is. A band has many parts and sections that come together to make its distinct sound and with this comes the different views of each band member. Many people in the band community are more or less defined by their instrument and which of the three categories their instrument falls under. Whether it be a Woodwind‚ Brass‚ or Percussion instrument they each come

Investigation into the photosynthetic activity of isolated chloroplasts from spinach beet to various light conditions. Introduction Chlorophyll‚ an important pigment in chloroplasts‚ is an essential component in photosynthesis; converting electromagnetic radiation from the sun into potential chemical energy. Photons excite electrons in chlorophyll which move through the electron transport chain‚ resulting in energy being stored in the bonds of ATP and NADPH. The flow of electron through the electron

be seen in the graph‚ the higher the temperature the shorter the time is for the Sulphur to be created. If it is looked as one continuous line‚ the first part of the trend line shows a steep‚ straight and constant decrease; then the 2nd part is not as steep and has a more gradual decline. Moreover‚ it shows how a reaction at 20°C a slower time for the cross to disappear compared to 40°C and especially 60°C. Both graphs show how temperature has a great effect on the speed of sulfur formation covering

Problem Question: * What effect does temperature have on the rate of Diffusion? Hypothesis: If we put the antacid in hot water‚ then it will dissolve faster than in cold water or room temperature water. Material List: * One thermometer * 3 beakers (of the same size) * 3 antacid tablets * Cup of ice * Hot plate * Paper towels * Water Procedures: Step 1: Gather materials Step 2: Label the beaker #1‚ #2‚ and #3 Step 3: Fill each beaker with the same amount of
