Conclusion In the workshop‚ we are going to design a beam that will rupture when a load of 20 kg is placed at its mid-span region. We have made much consideration and preparation before the testing. At the beginning‚ we considered to use wood or plastic to make the beam. After observation and research‚ we find out that wood is more suitable for making a beam and more possible to rupture at 20 kg weight. With several trials‚ we discovered that the shape‚ length‚ width and thickness of the wooden board

mass of Calcium carbonate in an egg shell Aim: is to find and work out the percentage of calcium carbonate by mass in eggshells by using acid base “back titration” Introduction: Calcium Carbonate‚ CaCO₃‚ is a compound which is polymorphic and therefore means that it can be found in a variety of different objects or organisms. For example: Rocks (limestone‚calcite)‚ sea snail shells‚ Eggshells‚ pearls and many more. This investigation will focus on finding out the percentage mass of calcium carbonate

We therefore conclude that no one can claim to truly know whether‚ or in what circumstances‚ euthanasia is moral. So‚ while it is possible to try to answer this question by discussing the moral issues‚ it is not easy to say whether euthanasia is ever morally supportable. Of course‚ euthanasia should be differentiated from simple removal of life support from a patient who has already effectively succumbed. The Churches‚ on good grounds‚ oppose euthanasia in all circumstances. We all regard life

JUTES METHODOLOGY ❖ Jute is a long‚ soft‚ shiny vegetable fibre that can be spun into coarse‚ strong threads. It is produced from plants in the genus Corchorus‚ which was once classified with the family Tiliaceae‚ more recently with Malvaceae‚ and has now been reclassified as belonging to the family Sparrmanniaceae. "Jute" is name of the plant or fiber that is use to make burlap‚ Hessian or gunny clothes. ❖ Jute is one of the most affordable natural fibres and is second only to cotton

In conclusion‚ after reading and observing all major religions of the world (Judaism‚ Christianity and Islam) are different in their concept of worshipping‚ fasting‚ festivals and tradition. I found one significant thing in all major religions that they believed in one God and accepts of God existence. No matter whom we are and belongs which religion but at end of the day we all standup on a single platform of one God. In Judaism‚ worship is only for God and God is everlasting with no concept of

E. Reactions of Aldehydes and Ketones with Sodium Hydroxide Objectives: To know the reactions of aldehydes and ketones with sodium hydroxide a) State the function of Sodium Hydroxide in the test. Sodium hydroxide (NaOH) is the oxidizing agent. b) What are the principles involved in the test? What is its purpose? Cannizzaro reaction is a reaction that uses a strong base‚ such as sodium hydroxide‚ which results to the formation of a carboxylic acid (or its corresponding salt) and an alcohol

Rate of Decomposition of Calcium Carbonate Theory Calcium carbonate‚ CaCO3‚is one of the most abundant minerals on the Earth. More than 4% of the Earth’s crust is composed of calcium carbonate. It is a major component in limestone‚ marble‚ seashells‚ bedrock‚ etc. Limestone and marble have been among the most widely used building materials for more than 5 000 years‚ from the pyramids in Egypt to the Parthenon in Greece and the Taj Mahal in India. In many places‚ limestone is also the foundation

Title: Preparation and Standardization of a Sodium Hydroxide Solution Objective/Purpose: The objective of this experiment will be the standardization of sodium hydroxide using potassium hydrogen phthalate by the titration method. Introduction: The concentration of solutions can be reported in terms of molarity and normality. Molarity is equal to: HCL‚ HBR‚ H2SO4‚ HNO3 M = mol Solute (mol) (Monoprotic) (Diprotic) _______________ V(L)g solutions (L)

Describe the role of calcium in muscle contraction‚ where it is stored‚ and how it is released and recycled. Calcium storage‚ release‚ and recycling Muscles need to be malleable or have plasticity in order to function correctly. This is where calcium comes into the picture. All muscles use calcium molecules for regulatory and signaling purposes. Contraction control and relaxation control by calcium is achieved first by the activation of troponin-tropomyosin with the actin filaments. The second
