Catalog Description:

CHM4211 - General Chemistry (5 hrs.)

[KRSN CHM 1030/1031/1032]

An introduction to chemistry which includes the study of matter, atoms, molecules, chemical arithmetic, chemical reactions, gas laws, acids and bases, organic chemistry, and laboratory experimentation. 

Course Classification:

Lecture/Lab

Prerequisite: 

MTH4411 Intermediate Algebra with Review or a higher level Math course with a grade of “C” or better completion within the past 5 years, or a Math ACT score of 18 or better or an equivalent assessment score.

Controlling Purpose: 

This chemistry course is the beginning or preparatory chemistry which is offered to students who have a limited science background.  It gives the student a knowledge of the basic concepts of chemistry which are needed to enter a major chemistry course or other advanced science course.

Learner Outcomes:  Upon completion of this course the student will read about, understand and successfully apply the basic concepts of chemistry:  atoms, elements, molecules, compounds, chemical reactions, chemical composition and quantities, modern atomic theory, chemical bonding and introductory organic and biochemistry.  In addition, the student will become proficient in application of chemical mathematics and laboratory procedures and techniques.

Unit Outcomes for Criterion Based Evaluation:

The following defines the minimum core content not including the final examination period. Instructors may add other content as time allows.

UNIT 1:  Introduction to Chemistry, Matter and Energy

Course Timeframe:

The U.S. Department of Education, Higher Learning Commission and the Kansas Board of Regents define credit hour and have specific regulations that the college must follow when developing, teaching and assessing the educational aspects of the college. A credit hour is an amount of work represented in intended learning outcomes and verified by evidence of student achievement that is an institutionally-established equivalency that reasonably approximates not less than one hour of classroom or direct faculty instruction and a minimum of two hours of out-of-class student work for approximately fifteen weeks for one semester hour of credit or an equivalent amount of work over a different amount of time. The number of semester hours of credit allowed for each distance education or blended hybrid courses shall be assigned by the college based on the amount of time needed to achieve the same course outcomes in a purely face-to-face format.
