This lab focused on three factors affecting reaction rates‚ temperature‚ surface area‚ and concentration. Our first experiment (table 1) looked mainly into the effects of temperature on the reaction rate. To see how different temperatures would change the reaction rates we had three flasks all containing varying temperatures of water(H20). One with cold water (4°C)‚ one room temperature (21°C)‚ and one with hot water (44°C). In each flask‚ we dropped one tablet of Alka-Seltzer‚ all within 0.008 grams

Under what conditions does 02 consumption provide a good estimate of the metabolic rate? Under Aerobic conditions. 2. What factors should be considered when the metabolic rate measured is to be a reliable measure of the basal metabolic rate? The animal must be resting. The animal must

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

The life from when Alejandra was five years old till today has had many changes and similarities over the past years. Changes overtime is a very good thing because that is how you grow and develop. However‚ there are things that do not change and stay similar. Some changes and similarities she will be talking about include her physical changes‚ family‚ and her personality. When Alejandra was five years old she was very small and short. Her hair was up to her shoulders‚ and she had pale skin. However

experiment is to find out the rate of reaction between Hydrochloric acid (HCL) and Magnesium (Mg) in different temperatures. The products that will be formed are Magnesium Chloride (MgCl2) and Hydrogen (H2). Prediction: I predict that as the temperature increases the rate of reaction also increases. To further explore the fact I further predict that the rate of reaction will double for every 10° C rise in temperature. I further predict as the temperature rises by 10° C the rate of collisions will also

However‚ it is important to note that literacy rates vary widely from country to country and after directly proportionate to a country’s wealth or urbanization level‚ although many other factors play a determining role. Illiteracy rates is an important factor in a country’s or a region’s “human capital”.

reverse repo rate These are the rates which are used by reserve banks (RBI in India) to inject or absorb liquidity from banking system. Repo rate is the rate at which the RBI lends money to the commercial banks or the rate it which banks borrow money from RBI. When RBI increases repo rate borrowing from RBI becomes more expensive. RBI increases repo rate to make it more expensive for the banks to borrow money. If RBI reduces the repo rate means banks can borrow money at cheaper rates. The term repo
