Ionic Compound Properties

"Ionic compound properties stem from their structure. Ionic compounds are found in lattice structures, making them extremely brittle. Ionic compounds have high melting points and form electrolytic sol ...

Types of Solutions

"Solutions are homogeneous mixtures. Different types of solutions have solvents and solutes in different phases. Solutes are dissolved in the solvent. In a solution in which carbon dioxide is dissolve ...

Ionic Bond

"In an ionic bond, two ions are held together by electrostatic force. These two atoms are trying to attain full valence shells of eight electrons. One atom has too many electrons and another has too f ...

Types of Reactions

"Scientists classify different types of chemical reactions using their behavior. Types of reactions include single displacement, double displacement, synthesis, decomposition and combustion." Fuente: ...

Investment Math Problems

"In Algebra II and in the real world, sometimes we need to solve investment math problems by using linear equations. When solving word problems using linear equations, we first need to pull out the re ...

Types of angles

"There are four types of angles: acute, right, obtuse, and straight. Each name indicates a specific range of degree measurements. Congruent angles have equivalent measures. Adjacent angles share a v ...

Two Column Proofs

"Two column proofs are organized into statement and reason columns. Each statement must be justified in the reason column. Before beginning a two column proof, start by working backwards from the "pro ...

Invertible Square Matrix

"In order to determine if a matrix is an invertible square matrix, or a square matrix with an inverse, we can use determinants. The only matrix with a nonzero determinant is an invertible square matri ...

Trigonometric Identities

"Identities are equations true for any value of the variable. Since a right triangle drawn in the unit circle has a hypotenuse of length 1, we define the trigonometric identies x=cos(theta) and y=sin( ...

Inverse Variation

"When modeling real world situations, we often use what's called inverse variation to describe a relation between two variables. Inverse variation is a relation in which the absolute value of one vari ...
