What process is used to group chemicals according to their physical properties?
observing
What are the columns used for on the periodic table?
the elements in a given column (or group) have the same number of valence electrons and hence similar chemical properties.
Why are elements in the same group undergo the same kinds of reactions?
Elements in the same group have similar chemical properties because they have the same number of valence electrons that are used in chemical reactions.
How can the periodic table be used to predict the properties of an element that has not been discovered?
It can't. the properties of an element determine it's group placement, without knowledge of these properties (or, indeed, the element itself) it would be impossible to place an element in it's proper place on the periodic table.
Which mathematical equations are used in astronomy?
Virtually all of them.
What properties of quality are frequently used to solve linear equations?
Quality does not normally play any part in linear equations.
How can you find the lumens by using area?
Area can be used to find lumens. There are specific equations that are used to find lumens and area can be included in these equations. Plug the numbers into the equations and the amount of lumens will be found.

Members
Which properties of minerals can be used in numbers?
I'm not sure but I belive that it is hardness
What process is used to group chemicals according to their physical properties?

What do you use oxidation numbers and their least common multiples to write?
They are used to write balanced chemical equations.
The domain for f x is all real numbers greater than or equal to?
This is a function. Functions are used in trigonometry and algebra equations. They are also used in calculus to find out a series of numbers.
What is alegebra?
Algebra is a part of mathematics in which letters and other symbols are used to represent numbers and quantities in formulas and equations.
Which tab in the properties dialog box of a group account is used to view the other groups that are members of this group?
Members
What two properties are 7 1-4 1 4?
There are two properties of these numbers are para-naphthoquinone and Naphthoquinone. This is used in math.
How could Mendeleevs table be used to predict the properties of elements that had not been discovered?
Comparing the properties of the new element with the properties of the other elements in the group we can make this prediction.
What type of problems have imaginary numbers?
Imaginary numbers are only ever used when you are using the square roots of negative numbers. The square root of -1 is i. You may find imaginary numbers when you are finding roots of equations.
