Experiment 7 Investigating Stoichiometry with Sodium Salts of Carbonic Acid Introduction: The student will perform the experiment in order to find the percent yield by using the theoretical value found using the balanced equation for sodium carbonate as well as sodium bicarbonate. The objective is to stabilize the substances by titrations and finding the percent yield when all the data is collected. The purpose of this procedure is so that the student will get better understanding of stoichiometry

Investigating the effect of pH on the activity of the enzyme catalase. Introduction Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colourless in a dilute solution‚ slightly more viscous than water. It is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching paper. Catalase is a common enzyme found in all living organisms. Its functions include the conversion of Hydrogen Peroxide‚ a powerful and potentially

Investigating the ‘Belief Bias’ Effect in Human Reasoning Abstract In this report an experiment was conducted to investigate the belief bias effect in human reason‚ the weighting attached to logic and belief in syllogistic reasoning. Belief biases were observed despite controls for conversion of premises. Belief bias was shown to be more marked in the invalid than the valid syllogisms. This consistent interaction between belief and logic was also noted. However‚ participants were intermediate

Deep vein thrombosis often occurs in patients having major surgery‚ particularly orthopedic surgical patients especially if they are immobilized for any length of time post-operatively. Deep vein thrombosis could eventuate in fatal pulmonary embolism; this is preventable with appropriate prophylaxis. Joanna Briggs Institute (2008) reviewed that the risk of deep vein thrombosis formation rises with the duration of the operative procedure and period of immobility. This paper will look at 5 different

Homicide What considerations need to be addressed when investigating a homicide? The considerations that need to be addressed are the following: The investigators needs to be careful to get evidence that identifies just one person‚ because they don’t want to accuse and even put in jail the wrong person‚ is preferable that the investigator has “smoking gun” at the time of press charges against someone. Also‚ investigators can’t let the personal beliefs or bias get it the way or cloud your thought

INVESTIGATING FACTORS AFECTING THE RATE OF PHOTOSYNTHESIS! Testing Carbon Dioxide Done by: Krish S. AIM: is to plan and carry out an investigation on factors affecting the rate of photosynthesis. We are doing this by investigating the amount of bubbles produced by waterweed to show the rate of photosynthesis and the effects of carbon dioxide (CO2). HYPOTHESIS: I think that the rate of photosynthesis will increase as the rate of CO2 increases this can be seen by the bubbles produced from
