Reactivity of metals with water and acid essay

The Reactivity Of Metals. To compare the reactivity of metals in oxygen, water and a diluted acid, and rate the metals from most reactive to least reactive. The beakers can get hot so use the wooden peg to move the beakers around.

  • Some might mention Office, one of Microsoft's powerful programs out;
  • If no reaction occurs, take strip out of test tube and start to heat water until it is 80 degrees Celsius;
  • Hedda Gabler struggles in this story to find happiness by making the people around her miserable;
  • They need to understand how to generalise from sufficient examples, and to see the limits to that generalisation in metals that do not react;
  • The nobler a metal is, the worse reducing agent.

The acid can be corrosive so handle with care. Using the Bunsen burner, you must watch your hair. When some metals burn they can be very bright so it can blind you for a while so do not look directly at it. The fumes form the acid are harmful if inhaled. Amount of water, amount of acid, length of strips, temperature of water, temperature of water when heating and concentration of acid.

  1. The nobler a metal is, the worse reducing agent. Teaching notes student sheet available with this resource and get the students to work each question after observing the reaction.
  2. The speed in was calculated as 1458.
  3. Place six test-tubes in the test-tube rack. If small crystals form on the glass rod, stop heating, otherwise continue until that point is reached.

OxygenHold Calcium in tongs and let it burn in Bunsen Burner for 20 seconds. Repeat step 2 with new strip of Calcium. Write down observations for results. Do steps 2-4 with the rest of the metals. AcidPour 2mL of Hydrochloric acid into 3 test tubesDrop Calcium into a test tube and swirl around for 15 seconds.

If reaction occurs perform a pop, oxygen and carbon dioxide test. Repeat steps 3 and 4 with a new strip of Calcium. Repeat steps 1-5 with the rest of the metals. WaterPour 5mL of water into 3 test tubes. Drop Calcium into test tube and swirl for 15 seconds. If Calcium reacts, perform the pop, oxygen and carbon dioxide tests.

If no reaction occurs, take strip out of test tube and start to heat water until it is 80 degrees Celsius. Once water reaches 80 degree Celsius, drop Calcium strip into hot water and move test tube away from Bunsen Burner.

If reaction occurs perform pop, oxygen and carbon dioxide tests. If no reaction occurs, remove strip and place in the steam formed. This might require heating up the water again. Write down observations for the results.

Repeat step 2-8 with the rest of the metals. Part A- Dilute Acid: Bubbled and fizzed up and formed a white precipitate. The test tube also heated up. HCl turned to a white murky colour. It bubbled and fizzed and the water a white precipitate. The calcium started to float. It had changed its colour to a white colour. It melted with the heat.

Tarnished into different colours. Once out of flame, it turned. This report give an experiment showing how to find the most to least reactive metal This is an experiment on how planaria regenerate body parts and an explaination as to how the experiment was performed 1473 words - 6 pages system.

When two flatworms join, each exchanges sperm and fertilizes the other's eggs. Their simple body plan also allows them to regenerate complete bodies from mere fragments by asexual reproduction.

Their body plan consist of a simple nervous system that includes a primitive brain, central nervous system, muscles, an internal reproductive system, intestines and an excretory system that includes specialized flame cells. In this experiment, a An experiment to find out if the emotional fluctuation was reflected in biological responses 2663 words - 11 pages AbstractThe experiment was to find out if the emotional fluctuation was reflected in biological responses.

Galvanic skin conductance, pulse and inter beat interval was used as indicators to measure the emotional fluctuation of the subject.

  1. If there is any doubt about the safety of this step, the teacher should first lift each beaker down onto the heatproof mat, using a thick cloth or wearing suitable thermal protection gloves, before the students add the zinc pieces. If older students perform these experiments, they can be asked to write symbol equations.
  2. If nothing happens, you may need to try again.
  3. Teaching notes student sheet available with this resource and get the students to work each question after observing the reaction.
  4. Add more zinc until no more bubbles form.

These informations were pick up by a computer through applying electrodes to the experimental subject. It was found that the actual statistical outcome did match with the expected outcome; there was a I have been asked to investigate how the temperature of an experiment 1094 words - 4 pages I have been asked to investigate how the temperature of an experiment affects the rate of reaction. In the experiment I will do it as the temperature of the hydrochloric acid.

Introduction I have been asked to investigate how the temperature of an experiment affects the rate of reaction. Reaction This is an essay on the life of John Paul Jones. He was the son of a Scottish gardener and was originally named John Paul. He sailed aboard merchantmen and slavers, becoming a first mate on a slaver brigantine by 1766 and receiving his first command in 1769.

In 1773, as the commander of a merchant vessel, he killed a Oxidation - Reduction. To range the metals copper, lead, silver and zinc together with hydrogen. Start with the strongest reducing agent. The nobler a metal is, the worse reducing agent.

Burnish the three metal strips to get a shiny surface IB Physics Thermodynamics Lab- "The purpose of this lab is to determine the identity of an unknown metal, and to prove whether the laws of thermodynamics hold when determining this identity. Measure the weight of the Pyrex beaker, and then pour 200 mL into the beaker.

Weigh the beaker filled with water. Record both weights to find the weight of the water by itself. Let this mass of water be labeled '1'. To make our lives easier and more luxurious we do things that give off Greenhouse Gases which end up affecting us for the worse, not for the better. Some examples of this are found below: Bangladesh is threatened by coastal flooding and is densely populated so the results could be very destructive and endanger many lives.

This essay is about the US's prohibitin from 1920 to 1933, how it started, and why it failed 1675 words - 7 pages Congress and the several States shall have concurrent power to enforce this article by appropriate legislation.

This article shall be inoperative unless it shall have been ratified as an amendment to the Constitution by the legislatures of the several States, as provided in the Constitution, within seven years from the date of the submission hereof to the States by the Congress. The National prohibition of alcohol was undertaken to reduce Microsoft: Some might mention Office, one of Microsoft's powerful programs out.

  • Measure the weight of the Pyrex beaker, and then pour 200 mL into the beaker;
  • Write down observations for the results;
  • Tarnished into different colours.

Some might also mention Bill Gates, who happens to be the richest man in the world. Microsoft is the most powerful company ever to be founded. Today An experiment to look at the effect of 1 factor on an enzyme 1586 words - 6 pages slow reaction time was a problem. Although I got sufficient results to support my conclusions, I would have liked to carry out an experiment to find the optimum temperature and denaturation point.

The reaction between catalase and H2O2 is exothermic. This means that the actual temperature inside the conical flask would be higher than desired.

This problem was unavoidable but affects the precision of my results.

Description

Due to the fact that Oxygen This is an essay on Hedda Gabler and how she needs to find happiness 1366 words - 5 pages Hedda Gabler's Obsession with HappinnessFinding happiness can be a struggle in many people's lives. In the story of "Hedda Gabler," Henrik Ibsen's shows how people's sadness can be the cause of a woman's happiness.

Hedda Gabler struggles in this story to find happiness by making the people around her miserable. Discuss any aspect of Said's work Orientalism,that you find most appealing, and give your own insights on the issue. Said, and the meaning of Orientalism from his point of view do not really make any sense.

He had many different points of view of Orientalism and he could not find only one way to describe Orientalism, he had many different definitions. For example, the Group I metals were some of the last metals to be discovered, because they are the most reactive, and Gold, Copper, and Silver were the first metals to be discovered because they are the least reactive, and so they are the easiest to find.

It takes a lot more energy to extract Sodium from its ore, than it does to extract Copper from the blue-green rock. Although there are some exceptions, mostly, the metals, the more reactive they are, the later they were discovered.

Reactivity of Metals with Water and Acid

My hypothesis towards the experiment was that magnesium would have a bigger reaction with the acids. The reactivity of an element depends on its ability to gain or loose electrons which are used for bonding.

The more reactive an element, the more easily it will combine with others.

  • This pair of experiments forms an important stage for younger students in developing an understanding of what an acid is;
  • In the story of "Hedda Gabler," Henrik Ibsen's shows how people's sadness can be the cause of a woman's happiness;
  • Record which metal you add to each tube.

From this information, I know that magnesium has a stronger ability to gain or loose electrons which makes the metal An Experiment To Find The Acoustic Impedance Of Paraffin And Water 1905 words - 8 pages An experiment to find the acoustic impedance of paraffin and water Abstract The speed of sound through paraffin and water was measured, and came close to the generally expected value.

The speed in was calculated as 1458. Then the density of these two liquids was measured, and combined with the speed of sound to find the acoustic impedance. The acoustic impedance of water was 1575 Other Popular Essays.
