Take Home Test Perchloric acid’s chemical formula is HClO4. This acid is not usually used alone. It is used for a solvent for metals and alloys a dehydrating agent‚ particularly in the determination of silica in iron and steel and in cement and other silicate materials. It is also used as a solvent for sulfide ores for the determination of copper and other metals‚ in the separation and determination of the alkali metals sodium and potassium. In the manufacture of anhydrous magnesium

In the melting work centre the workers also observe the process and wait for the alloy to melt.Then the workers are waiting for the right temperature in the furnace for 20 min. Unused employee creativity Since it is a lot of waiting time in the system some of the workers creativity is unused. The casting manager has responsibility

Her framework was fabricated of a right and sturdy alloy know as duralumin. Sixteen gas cells were placed throughout the huge ship. The gas cells were gigantic like an engine room. It held the hydrogen and that’s what powered the huge ship. Hydrogen was also the reason the ship went up in flames. The Hindenburg

C2.1.1 Structure and bonding a) Compounds are substances in which atoms of two or more elements are chemically combined. b) Chemical bonding involves either transferring or sharing electrons in the highest occupied energy levels (shells) of atoms in order to achieve the electronic structure of a noble gas. c) When atoms form chemical bonds by transferring electrons‚ they form ions. Atoms that lose electrons become positively charged ions. Atoms that gain electrons become negatively charged

While the electroplating is in progress‚ additionalsalts of the metal to be plated must continually be added to the platingsolution‚ or else the anode must be renewed‚ if it consists of the platingmetal. If the coating metal does not form a strong alloy with the metal to be plated‚ it may be necessary to first coat with an intermediate metal; for example‚ when plating silver on steel‚ it is customary to first place a coating of copper over the steel. When plating gold or silver‚ it is customary to

ways to practice alchemy. However‚ modern science of chemistry has stated clearly that alchemy is not a feasible scientific method. Alchemists could never turn other metals into gold. The only thing they did was combining two or more metals into alloy or plating a golden colour on the surface of the metals.

of the methods used for calculating this characteristic is the tensile test‚ where a sample is pulled apart by a Tensile Testing machine until it brakes. The aim of this experiment is to perform tensile tests on samples of standard steel‚ aluminium alloy and copper in order to calculate Young’s Modulus. In addition to this‚ also yield stress‚ tensile strength and percentage elongation and reduction of area will be calculated‚ only for the standard steel sample. Theory Young’s Modulus (E) Stress (

Blast furnace is a continuous unit of shaft-type. The charging of burden is conducted from above‚ through the typical charging unit‚ which is the gas damper of the blast furnace. It is reduced rich iron ore (at present time resources of rich iron ore are preserved only in Australia and Brazil)‚ sinter or pellets in the blast furnace. Sometimes granular pellets are used instead of crude ore. Blast furnace consists of five constructive elements: top cylindrical part is top throat‚ that is necessary
