This experiment is to show how much carbon dioxide is produced during the reaction between an acid (hydrochloric acid) and marble. Equipment: Hydrochloric Acid (20ml) - 0.5M‚ 1M‚ 2M Marble Chips (2g per test) Large Measuring Cylinder Plastic Bowl (3/4 full of water) Rubber Tubing Glass Conical Flask Stopwatch Method The first thing that we did was fill the plastic bowl with water. We only filled it up 3/4 of the way because otherwise the water displaced into

Atausch July 28‚ 2014 Bio 102 Lab Final Exam: Acids and Enzymatic Reaction Purpose: To examine how an acidic fluid will modify the outcome of an enzymatic reaction. Introduction: Enzymes are “specialized proteins made by living cells that serve as biological catalysts.” (eScience Labs‚ LLC‚ 2013) These enzymes “allow certain industrial processes to be carried out at normal temperatures and pressures‚ thereby reducing the amount of energy and expensive equipment needed.”(BBC‚ 2012) Enzymatic

The life in a living hell will continue in the coming "Salem" Season 3 Episode 4 "Night’s Black Agents." Everyone should be very careful of their moves as the Dark Lord keeps an eye on all of them. In the promo trailer of "Salem" Season 3 Episode 4‚ Anne (Tamzin Merchant) can be seen warning Cotton (Seth Gabel) to be very careful as he stays in the woods or else‚ he will be in grave danger. However‚ Baron (Joe Doyle) believes that if ever Cotton makes it out of Boston alive‚ the Dark Lord will still

For known amounts of reactants‚ theoretical amounts of product can be calculated in a chemical process. These calculated products are determined using the limiting reagent‚ (the substance that runs out first which stops the reaction) and are called the theoretical yield. The theoretical yield is the amount of product that should be acquired during the experiment if all aspects go perfectly. However‚ due to experimental errors‚ very few labs do so. These results are called actual yield. The percent

Aim: The aim of my 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

What is Your Favourite Season? Why? The question of what is my favourite season is a difficult one to answer. Almost everyone will give a different response‚ for there are as many positive points to each of the four seasons as you can possibly imagine. Nonetheless‚ I agree that my favourite season is summer and the three main reasons are that summer is a time to relax and enjoy yourself‚ the weather is seldom cold or rainy‚ and it is a great opportunity for families to travel. To start with‚

Dreams‚ everyone has dreams‚ but can it really be attained in a good way? Does the way that man do things are in coordination of his free will? Or maybe it’s just the natural forces that shape and determine his character. “Requiem for A Dream” is a movie that talks about the drastic lives of three people. Lives which have been deeply influenced by what they see and experience in their surroundings. Moreover‚ these influences have forced them to become someone else. Sarah‚ Harry‚ Marion‚ and Tyron

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)
