the effect that the concentration of hydrochloric acid (independent variable) has on the rate of reaction (dependent variable) between the magnesium ribbon and the hydrochloric acid. Hypothesis As the concentration of hydrochloric acid increases‚ the time taken for the magnesium to disappear will decrease. (The greater the concentration of hydrochloric acid‚ the faster the reaction between the magnesium and hydrochloric acid will occur.) In addition‚ doubling the concentration of hydrochloric acid

The effect of nutrient concentration on duckweed growth Gina Neonakis Biology 203L:11 Biology 203:10 November 14‚ 2011 Abstract Lemna minor‚ or duckweed‚ is a small plant that floats on the surface of stagnant water that is usually rich in nutrients. Phosphorus is an important macronutrient in the growth of aquatic plants. We tested the effect of phosphorus on duckweed population growth using a control medium rich in nutrients and compared it to the population growth in a medium that lacked

Numerous events forced the Catholic Reformation. These events were heavily embedded in the clergy exploitation of the Christian doctrine. In that era the text and the sermons were given in Latin unfortunately‚ majority of the congregation if not all of the congregation did not speak Latin. Consequently‚ they were unable to comprehend the sermon. Additionally‚ the clergy did not live in their own diocese‚ or speak the native language therefore‚ they could not sympathize to the needs of the population

moving slower. Part B: Title: The effect of salt concentration on osmosis in potato. Introduction: 1. The purpose of doing this lab is to observe the effects of various solute concentrations on osmosis in a potato. 2. During osmosis‚ water moves from the side of the membrane where they are most concentrated to the side where they are less concentrated. If the concentration is equal on both sides‚ there will be no movement. 3. I hypothesize that the mass of the potato will decrease

fact there were many unhappy freemen wandering the Virginia area because they had no wife or land. This rebellion resulted due to the fact Governor Berkley was friendly towards the indians and prohibited people from taking land any further west than what has already been established. As a result of Berkley’s actions‚ Bacon and his fellow freemen murdered many Indians‚ dispelled Berkley from Jamestown‚ and burned the settlement to ashes. These actions demonstrated

Osmosis coursework Aim: To investigate the effect of different concentration of a sugar solution on the amount of osmotic activity between the solution and pear pieces of a given size. Define osmosis: Osmosis is a net movement of water/ solution molecules from a region of high concentrated area to a region of lower concentrated area through a semi-permeable membrane which lets smaller molecules such as water through but does not allot bigger molecules like glucose to pass through. The molecules
