## Questions

### Subject: Chemistry

What are the basic concepts taught in chemistry?

There are several basic concepts one must know to be successful in chemistry. How to read a periodic table and know the basic concepts of elements such as atomic mass, atomic number, and symbol is the first basic concept. Some of the other important topics is chemical reactions, how to balance chemical equations, performing stoichiometry, compound nomenclature, limiting reagents, electron configuration of atoms, acid-base reaction, ideal gas laws and equations, buffer solutions, titrations, different types of chemical bonds, structures of atoms, molecular geometry, hybridization of orbitals, mixtures and intermolecular forces, redox, rate laws, thermodynamics, etc.

### Subject: Statistics

What are some of the main concepts of basic statistics?

Some of the main concepts taught in statistics classes are confidence intervals, probability, how to draw conclusions from data sets provided, how to determine how to read data analysis for variation, degree of uncertainty, outliers, areas of distribution, regression coefficients, when to accept or reject null hypothesis, and other terms.

### Subject: Algebra

How are slope, point-slope form, standard form, and slope-intercept form of linear equations related?

Slope is a necessary component of all three forms of linear equations. If a student is given a single point and the slope of a line they will be able to determine the equation of the line using point-slope form. From there they can either transform the equation into slope-intercept form or standard form. If a point is not given but a linear equation is given in either standard form or slope-intercept form, the student can determine the slope and y-intercept from these equations either through simple math or directly from slope-intercept form. Graphing these solution sets can be determined from there given the circumstances of the problem.
