from. Bangladesh has a lot of floodplains and it is very hot. For my house roof the first layer on the frame would be 15mm of triplex nailed on to the frame of the house. The design will have corrugated galvanised iron on the frame. If the water went through the corrugated galvanised iron‚ it is able to slide the water down outside. There will be big pipes on the end bottom of the roof bringing the water beside the house and using it to take showers and etc. As the floor of the attic‚ I will put a

Manganese would be a solid. It would be classified as a metal. The color would be silver/grey. When armies were at war their helmet was made out of steel and 12% Manganese. In 1942 nickels were made out of 9% Manganese. Manganese can rust in water like iron. Manganese is also an important part of our body. Manganese can help our bodies in many ways and ruin our bodies to. Scientist shows that without Manganese we wouldn’t be able to heal from surgery faster‚ helps from bone loss‚ and is an antioxidant

Hypothesis: I think that the chemical change is an irreversible process. The wet iron filings by the next day it will turn into rusting material because it is exposed to the atmosphere. While the dry iron filings is not III Materials: The setup in the previous activity‚ small plate‚ dry iron filings. IV Procedure: 1. Place the iron filings on a dry plate. 2. Compare the physical properties of the dry and wet iron filings. 3. Take note of the differences in their physical properties if any.

Iron Man: The Real Hero In today’s society‚ the concern of people and laws are not about doing good but rather having the appearance of good. People no longer care about what they need to stand for‚ only that they look like they aren’t sitting down. In fact‚ men today are treated as outcasts when sticking up for a good thing when it doesn’t have a pleasant appearance. Men such as Thomas Jefferson‚ Leonidas‚ Joshua and Jesus‚ men that represent something greater than what meets the eye‚ are scarce

Hypothesis: Rust is a reddish or yellowish-brown flaky coating of iron oxide that is formed on iron or steel by oxidation‚ especially in the presence of moisture. The rusting process is electrochemical‚ meaning it forms from a chemical reaction which takes place in a solution where there is an electron transfer between the electrode and the electrolyte or species in solution. In the case of rusting‚ the transfer of electrons from iron to oxygen begins the electrochemical process. Electrolytes accelerate

Quantitative Analysis: % Copper in an Ore May 3‚ 2006 Abstract: In this experiment we were given an unknown sample of ore. Using the spectrophotometric analysis and the electrogravimetric analysis‚ we found the unknown percentage of copper in the unknown sample of ore was to be 17.6% by mass. Introduction: Chemical analysis takes place under two different scenarios. In one case‚ you need to find out the chemical identity of some material. The first kind of analysis‚ in which the chemical

many protective paints and sealants don’t defend against rust. Salt water penetrates the protective layers to corrode the metal. Corrosion in iron Rust on iron is produced in sea water when iron (Fe) comes in contact with oxygen. The reason for this is because when water interacts with iron it conducts a small amount of current that flows through the iron. Salt increases the amount of ions in water allowing it to become a better conductor. The full chemical equation for this process theoretically
