Introduction Representing molecules as images allows us to impart a great deal of information concerning molecular structure. But these molecules can also be named‚ and there are occasions when this is more convenient than drawing a picture. In the early days of chemistry‚ the list of known compounds

Scenario experiment AIM: To investigate one factor that affect the distribution of hydrogen peroxide by the catalase in this organism. In this catalase and hydrogen peroxide experiment‚ we will find out how enzymes act as catalysts by causing chemical reactions to occur. Using a potato and hydrogen peroxide‚ we can

Lab 7: Catalysts Introduction Pre-Lab Questions 1. What is a catalyst? An enzyme is a biological catalyst that speeds up chemical reactions in the body. 2. If you continue to add more catalyst will the speed of a reaction always continue to increase? Explain your answer. It will continue to speed up the reaction until there is more catalyst than the limiting reactant. 3. In this lab you will produce oxygen and water from hydrogen peroxide (H2O2). Write a balanced reaction equation for this reaction

Oratorical Piece Theme: “Students as Catalysts for Peace” Friends‚ let me begin by quoting you a line lifted from Eleanor Roosevelt. “It isn’t enough to talk about peace. One must believe in it. And it isn’t enough to believe in it. One must work at it.” This ladies and gentlemen challenges Juan De la Cruz‚ the majority common Filipino people. And what is more moiling to this are the sweet and sour additives and influences of the society. My friends‚ as we all know Philippines is somehow ignorant

Analysis of a Chemical Mixture Using the Ideal Gas Law The objective of this experiment was to determine the composition of the NaNO2 mixture in the net ionic reaction of NO2-(aq) + HSO3NH2(aq) → HSO4-(aq) + H2O(l) + N2(g) in unknown mixture number nine. It was known that NO2-(aq) and HSO3NH2(aq) were in a stoichiometric 1:1 molar ratio. In trial one the percent mass of NaNO2 in the unknown mixture was 59.30%. In trial two‚ the percent mass of NaNO2 was 63.47%. Lastly in trial three

the benefit of climbing beans. And they are easy to harvest! The Organic Farmer A large section of the Kenyan population is unable to afford high protein food with adequate proteins‚ such as meat and eggs. This is where beans play a very important part; they are a cheap source of proteins. Unfortunately‚ the production of beans in most parts of the country is declining. The problem is the lack of good seeds . A survey by The Organic Farmer at the beginning of March this year indicated that most of

1. Introduction: This investigation will show the effect of temperature on the rate of reaction. The Berocca tablet was reacted with hot water (47oC) and then with cold water (20oC). In the hypothesis‚ it was predicted that the temperature will be inverse proportional to the time Berocca tablet reacts with water to produce 50ml of carbon dioxide gas. Through the result table‚ we can see that the hypothesis is supported and it was correct. In the conclusion‚ it was shown that the temperature has the

Effect of Cohabitation on the Rising Divorce Rate The rise of the divorce rate seems to be due to the lack of commitment or understanding of love and longevity in a marriage. Cohabitation can be defined as an arrangement whereby two people decide to live together on a long term or permanent basis in an emotionally and /or sexually intimate relationship (Brannon 2008). Cohabitation is seen as the best way to understand a prospective mate in terms of living and financial stability
