quartz, a form of SiO2, which contains an ordered array of neutral, covalently bonded nonmetal units, is an example of

a. alloy

b. amorphous solid

c. metallic solid

d. ionic solid

e. molecular solid

Expert Solution

In order to answer this qurstion,we need to cinsider the method of elimination,

An alloy is made up by mixing of two or more metallic substances(general),to have some desirable traits,quartz does not qualify this criteria as it is not an alloy of silicon and oxygen.

As mentioned in the question an ordered array of units,which suggests that it is not an amorphous solid either.Quartz is a crystalline form od sio2

Metallic solids are composed of metal atoms and quartz does not qualify this criteria agin because it is composed of non metalallic atoms

Ionic solids are made up atoms that are charges and form ionic bonds.Like in NaCl with Na having a positive charge and Cl having a negative charge they form an ionic solid.Quarts has no ionic counterparts as both the constituents are non metallic.

So,quartz is a molecular solid in which numerous Sio2 molecules are held together by covalent bonds and in an orderly arrangement.

Answer:e.a molecular solid

Create a “Main” method that contains two 2-Dimensional arrays of characters. The first array, which we will call our visible field, needs to be 5 by 5 and should initially hold the underscore character “_”. This will be used in our game of minesweeper to represent the possible locations the player can check. The second array, which we will call our hidden field, should also be 5 by 5 but filled with the capital letter "S” which means safety. However, we...
