Lithium‚Sodium‚Potassium‚Rubidium‚Caesium and Francium are all part of group 1.They are metals that can be easily cut.After being cut‚it is shiny but it quickly tarnishes due to the fact that the metal reacts quickly with oxygen or water.The shiny surfaces of Sodium quickly tarnishes more quickly than Lithium and Potassium more tarnishes more quickly than Lithium.This shows that the reactivity increases as we move down the group.

Light and Dark Minerals Compare and contrast Essay. Have you ever wondered about light and dark minerals? Although they’re different from each other‚ they are alike in many ways. Dark and light minerals do have similarities like the eight elements. These two minerals helped form rocks in today’s society. Dark minerals are different from light minerals because of the colors. These minerals are Pyroxene‚ Amphibole‚ Olivine‚ Calcium Feldspar and Iron. The dark minerals form dark colored rocks

2. Element X melts in boiling water‚ it fails to react with hydrochloric acid; and 1 cm3 of element X has a mass of 1.8 grams. Is element X a metal or non-metal? Give the reasons for your answer. Element X is most likely a typical non-metal. First of all‚ element X melts in boiling water; non-metals typically have low melting and boiling points. Furthermore‚ element X is unable to react with hydrochloric acid. This greatly indicates that element X is a non-metal as most non-metals fail to

I think that we should and should not mine minerals.We should because it gives resources.We shouldn’t because we lack trained people and fuel. We can mine and find many resources.For example‚ minerals. The minerals we can find can be worth millions of dollars.We can fine minerals like silver‚gold‚copper‚lead‚tin‚and zinc.We can also use these to create thing not just for money. We can mine and find another resource.This resource is fuel.This is what we use to drive cars.The fuel could also

Rotary kiln is refers to rotating calcining kiln (also known as rotating kiln)‚ which belongs to thermal equipment. Rotary kiln can be divided into metallurgy kiln‚ chemical engineering kiln‚ and building material kiln according to its different dealing materials. The building material kiln is mainly used in calcining clinker cement‚ limestone and porcelain granule. Metallurgy rotary kiln is mainly used for the magnetizing calcining of lean iron ore in iron and steel plant in metallurgy industry

Before the 1900s‚ tin was commonly used to package household foods. Since it protected the foods inside‚ and it could be bent with ease‚ it was regarded as an inexpensive‚ easy and health conscious way to keep foods fresh. Some of its disadvantages‚ which lead to its defeat to aluminum‚ included the fact that it could only be rolled thicker than aluminum; it became brittle when warm‚ reducing its malleability greatly‚ and the tin foil created a strange aftertaste‚ which was undesirable to many.
