1.)The symbol for Iron is Fe because Fe comes from its latin name "Ferrum." 2.)A metalloid is an element germanium or silicon whose properties are intermediate between those of metals and solid nonmetals.
I asked a question last week about how they get sugar from cane sugar.This is what I found. Mills extract raw sugar from freshly harvested cane, and sometimes bleach it to make white sugar for local consumption. Factories, often located nearer to buyers in North America, Europe, and Japan, then produce refined white sugar, which is 99 percent sucrose. Increasing affluence in the sugar-producing tropics increased demand for refined sugar products, driving a trend toward combined milling and refining.Sugar refining further purifies the raw sugar. It is first mixed with heavy syrup and then centrifuged in a process called "affination". Its purpose is to wash away the sugar crystals' outer coating, which is less pure than the crystal interior. The rest of the sugar is then dissolved to make a syrup, about 60% solids by weight. The sugar solution is clarified by the addition of phosphoric acid and calcium hydroxide, which combine to precipitate calcium phosphate. The calcium phosphate particles entrap some impurities and absorb others, and then float to the top of the tank, where they can be skimmed off. An alternative to this "phosphatation" technique is "carbonatation", which is similar, but uses carbon dioxide and calcium hydroxide to produce a calcium carbonate precipitate. After filtering any remaining solids, the clarified syrup is decolorized by filtration through activated carbon. Bone char is traditionally used in this role.[10] Some remaining color-forming impurities adsorb to the carbon. The purified syrup is then concentrated to supersaturation and repeatedly crystallized in a vacuum, to produce white refined sugar. As in a sugar mill, the sugar crystals are separated from the molasses by centrifuging. Additional sugar is recovered by blending the remaining syrup with the washings from affination and again crystallizing to produce brown sugar. When no more sugar can be economically recovered, the final molasses still contains 20–30 percent sucrose and 15–25 percent glucose and fructose. To produce granulated sugar, in which individual grains do not clump, sugar must be dried, first by heating in a rotary dryer, and then by blowing cool air through it for several days.A LOT OF STEPS ISN'T IT!?
Q : How Long Does It Take For Lava To Cool Down And Become A Rock ?
A: Lava is extremely hot. Lava can reach temperatures of about 1,250° Celsius. The lava of the Hawaiian volcanoes reach these temperatures. Normal lava temperatures reach 750° Celsius. That is still much hotter than your oven is capable of reaching.

ReplyDelete2.)A metalloid is an element germanium or silicon whose properties are intermediate between those of metals and solid nonmetals.
They are semiconductors.
ReplyDeleteAwesome job Trinity!!!! 2 extra credit points for you!
ReplyDeleteMetalloid is a nonmetal that in combination with a metal forms an alloy ( a stubstance compose of 2or more metals)
ReplyDeleteExcellent Kyle! Extra credit for you too!

Q: How Hot is Lava To burn you.
ReplyDeleteA:100% yes, lava ranges from 700 to 1200 degrees so it would be like being in an oven even if you were 10 feet away
Q:Where Does a Scarlet Fever come From.?
ReplyDeleteA: It is caused by a group of streptococcal bacterial with common disease .
Q : Why is iron Fe ?
ReplyDeleteA: Some symbols of the elements are taken from the Latin names of the elements. In iron's case, it's Latin name is ferrum.
Q: What is metalloid .?
ReplyDeleteA: A nonmetallic element, such as arsenic, that has some of the chemical properties of a metal.
