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

Figure 2. The rate at which the reaction occurred for the 100% concentration is 1.45 mg/dL per minute. For the 50%‚ the rate was 3.05 mg/dL per minute‚ and for the 25%‚ the rate was 2.76 mg/dL per minute. As seen‚ the rate fluctuated from the lowest rate at 100% and the greatest rate occurring at 50%. As mentioned earlier‚ the Collision Theory states the rate of a chemical reaction is proportional to the number of collisions that occur. One way to increase the number of collisions is to increase

exchange rates‚ which is useful for international finance assignment. Exchange Rate is the price of one country’s currency in terms of another country’s currency; the rate at which two currencies are traded for another. It measures the number of units of one currency which exchange‚ in the foreign exchange market for one unit of another. Exchange rates are important because‚ they establish the relationships between the different currencies or monetary units of the world. Exchange rates have been

Lower education rates will raise recidivism rates because many prisoners who lack education and re-enter society will not be self-sufficient as education provides the basis for employment. Heather Ongley Lorena Quintero Amanda Winter Darren Robinson CJA/334 Philip Russo September 17‚ 2012 Introduction Before understanding the research to be conducted‚ one must understand the who‚ what‚ when‚ and why of the issue.

Discussion The purpose of this experiment was to determine if splitting a bean would affect its rate of respiration. Splitting a bean does not impact its rate of respiration. This is shown in the data‚ while the average rate of respiration for Whole beans is 1.35 and the rate of respiration for 1.16‚ the standard error of the mean is .15. Because the standard error of the mean is so high‚ they overlap in both of the data sets‚ which shows that the data is very similar. This is better shown in the

Module 02 Case Study: Integumentary System Part I—"Soaking Up the Sun" Questions 1. What are some differences between Judy and Mariah that might make Judy more "at risk" for skin cancer than Mariah? (2 points) --Some of the differences would be the coloring of their skin. Mariah has darker pigmentation‚ with dark hair. Mariah has more melanin in her skin giving her more protection from the sun‚ unlike Judy‚ who has light skin‚ with red hair and blue eyes. Also the fact that Mariah goes out in

One view is that the literacy rate has risen from 72% to 90% in the last 30 years. According to the 2005 Functional Literacy‚ Education‚ and Mass Media Survey conducted by the National Statistics Office (NSO)‚ 48.4 million or 84% of the estimated 57.6 million Filipinos who are 10 to 64 years old are said to be "functionally" literate (Source: "8 out of 10 Filipinos are functionally literate" by D.

The Correlation between the Diffusion Rate of a Substance and its Molecular Weight ABSTRACT To test the effect of molecular weight on the rate of diffusion‚ various experiments were performed. One of which is the glass tube test wherein cotton balls of the same size were moistened in two different substances (NH4OH and HCl). These cotton balls were plugged at each side of a glass tube. After some time‚ formation of a white ring occurred. The white ring‚ in fact‚ is a product of the reaction between

can be potentially more important for the next generation than it is for us. The issue is birth rate or population‚ what it is now and what it will be in the future. First of all‚ what is birth rate? The birth rate is the total number of births per 1000 of a population in a year. As you may know‚ by subtracting the death rate from the birth rate we will result in the rate of population. Here is a display of the birth rate from 1950 to 2015. Year Birth rate 19501955 37.2 19551960 35.3 19601965 34.9
