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 the concentration

AIMS The aim of this experiment was to investigate the effect of temperature rise on the rate of transpiration of a plant (hibiscus) by measuring the plant’s water uptake in a period of time. HYPOTHESIS Transpiration is the process by which plants loses water to the atmosphere from their leaves. Water in the plant is lost to the atmosphere by evaporation. Evaporation of water can occur at any temperature. In the presence of sunlight‚ water in the plants evaporates into the intercellular air

According to human resource experts‚ the average attrition rate is projected to grow at 31 per cent in Indian firms in the April-June quarter‚ a rise of 9-10 per cent from the preceding quarter (January-March). SPECIAL: Best companies to work for India In the April-June quarter of 2011-12‚ the average attrition rate was 27 per cent. Generally‚ employees would have received their annual appraisals during the April-June period and those not happy with their performance review or salary hikes

birth and death rates‚ infant mortality‚ fertility and natural increase rate‚ and life expectancy. First of all‚ these two countries have drastically different Crude Birth Rates‚ or CBR for short. Crude Birth Rates are devised by how many babies are born per one thousand people in one year. The CBR in Haiti is 25.63 babies per one thousand people. That means if you were to take one thousand people‚ there would be roughly 26 babies born in 2016 alone. However‚ the Crude Birth Rate in Hungary is far

of this practical is to investigate the effect of exercise on heart rate and breathing rate. We will use a digital heart rate monitor strapped on our chest while we perform different levels of exercise. A digital watch is also provided which receives signals from the heart rate monitor and displays your current heart rate on the screen. To measure the breathing rate at different levels of exercise‚ we measure the breathing rate before physical activity by counting the number of breaths in 10 seconds

exact value is impossible because of varying variables e.g. room temperature‚ depth of container etc. However by applying newton’s laws you can estimate a point at which to start testing the food for safe food storage. A container of hot water at temperature‚ T‚ placed in a room of lower temperature Troom‚ will result in an exchange of heat from the hot water to the room. The water will eventually cool to the same temperature as the room. You observe this cooling process every time you wait for

variables In this lab‚ we will be studying the difference of heart rate between boys and girls. There are many things that can increase heart rate‚ such as exercise‚ drinking coffee‚ taking certain pills‚ drinking an energy drink‚ feeling a strong emotion‚ etc. I have chosen to use exercise as a means of increasing the heart rate of my subjects‚ more precisely‚ 20 sit-ups. There are many reasons why your heart rate increases when you exercise‚ the most important one being that your muscles require

Spot Rate and Forward Rate Spot Rate: It is nothing more than the YTM on bond. It is the rate of interest on bond maturing at any time in the future. It is also known as geometric average of 1 year forward rates in the future. Hence‚ YTM on bonds can be calculated as: When forward rates are given then; oS1 = oF1 oS2 = [(1+of1)(1+1F2)](1/2) -1 oS3 = [(1+of1)(1+1F2)(1+2F3)](1/3) -1 and so on. Forward Rates: It is the interest rate established today ‚ that will be paid on money to
