Some metals react with acids while others do not. In this experiment‚ students will perform 2 reactions: aluminum/zinc with excess 6M hydrochloric acid and aluminum-zinc alloy with excess 6M hydrochloric acid. The purpose of this experiment is to determine the atomic mass of each metal and the percent composition of a known mass aluminum-zinc alloy by determining the moles of H2 gas formed. Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g) 1 mole of H2(g) is produced for every 1 mole of Zn(s) 2. 2Al(s)

Photosynthesis is a process through which plants and some certain types of bacteria get energy from the sun’s UV-rays and use it to create and store sugar that is transformed into ATP by cellular respiration later on in the process. In plants‚ this process takes place in chloroplasts‚ which concentrate in the mesophyll cells‚ with the help of chlorophyll‚ the green pigment‚ which is directly involved in photosynthesis. It is important to understand that we see leaves green simply because the green

Light and Dark: The Women of Heart of Darkness Joseph Conrad’s Heart of Darkness is an intricate and complex novella that is difficult to interpret. While it functions on a myriad of levels‚ examining issues such as race‚ moral ambiguity‚ and madness‚ most prevalent is the examination of imperialism. Conrad does not take a clear and firm stand either for or against the rhetoric of imperialism‚ though the story certainly points out the hypocrisy of the invasion of an untamed and primeval land in

What is the difference between ecosystem and ecology? Ecosystem is the physical system (an open system) in which the mutual interaction between biotic and aboitic component motored by the energy component is studied. While the Ecology is the science which study the interrelation between Abiotic (inorganic) and Biotic (organic) components as well as the interaction among the biotic component. To make it more clear‚ ecosystem is the fundamental unit of ecological study. Ecology vs Ecosystem

Photosynthesis (pron.: /foʊtoʊˈsɪnθəsɪs/; from the Greek φώτο- [photo-]‚ "light‚" and σύνθεσις [synthesis]‚ "putting together"‚ "composition") is a process used by plants and other organisms to convert the light energy captured from the sun into chemical energy that can be used to fuel the organism’s activities. Photosynthesis occurs in plants‚ algae‚ and many species of bacteria‚ but not in archaea. Photosynthetic organisms are called photoautotrophs‚ since they can create their own food. In plants

Based off the results from this lab the student was able to determine and have an overall better understanding of the variables that affect the rate of photosynthesis in a plant. The first variable the student tested in the lab was 30cm of light with CO2 present. The student started this trial with all 10-leaf disks and timed how many leaf disks came up every minute for 15 minutes. One minute into the trial and the student recorded that no leaf disks had yet to rise to the top of the solution. At
