Question

heeeeeeeelp please

Look at the periodic table. List three metallic elements and three nonmetallic elements. Write both the symbol and name, such as "Re, rhenium" Name an example of a ceramic material in each of the following categories AND an application of your example material: a ceramic containing oxygen (a metal oxide) a ceramic containing carbon (a metal carbide) a ceramic containing nitrogen (a metal nitride) What oxide compound is the primary constituent of glass? Write the chemical formula as well as the name in words. Give two examples of a composite material. Clarify the constituents of each composite usually some kind of fiber embedded in some kind of matrix. Identify the fiber and the matrix

Explanation / Answer

nonmettalic: hydrogen=H , carbon=C, Nitrogen=N

mettalic: Aluminum: Al , Iron:Fe, copper: Cu

2: metal oxide: A metal oxide is the basic anhydride of a base, and therefore, the reaction between the metal oxide and an acid is essentially an acid base reaction that produces a salt and water.

Na2O(s) + HCl(aq) --> NaCl(aq) + H2O(l)

metal carbide: calcium carbide Calcium carbide is a chemical compound with the chemical formula of CaC2. Its main use industrially is in the production of acetylene and calcium cyanamide.[2]

metal nitride:a compound of nitrogen with a more electropositive element, for example magnesium nitride, Mg3N2

3.Silica (the chemical compound SiO2) is a common fundamental constituent of glass. In nature, vitrification of quartz occurs when lightning strikes sand, forming hollow, branching rootlike structures called fulgurite.

4.Composite materials (also called composition materials or shortened to composites) are materials made from two or more constituent materials with significantly different physical or chemical properties, that when combined, produce a material with characteristics different from the individual components. The individual components remain separate and distinct within the finished structure. The new material may be preferred for many reasons: common examples include materials which are stronger, lighter or less expensive when compared to traditional materials.

Typical engineered composite materials include:

Composite building materials such as cements, concrete

Reinforced plastics such as fiber-reinforced polymer

Metal Composites

Ceramic Composites (composite ceramic and metal matrices)

example1: Wood is a naturally occurring composite comprising cellulose fibres in a lignin and hemicellulose matrix

example 2: Concrete is the most common artificial composite material of all and typically consists of loose stones (aggregate) held with a matrix of cement.
