While the ionic composition of surface seawater is basically the same anywhere in the world's oceans, the chemistry of inland waters can vary by orders of magnitude over short distances. In this activity we explore a data set on surface water chemistry in almost 5000 lakes across the Nordic countries (Norway, Sweden, Finland). Water chemistry of lakes in this mostly sparsely populated region does not carry a strong signal from local human activity. This allows us to explore large-scale gradients related to distance to the ocean, soil and landscape characteristics, post-glacial history, and effects of long-distance pollutant transport processes.

Inorganic chemistry is concerned with the properties and reactivity of all chemical elements. Advanced interests focus on understanding the role of metals in biology and the environment, the design and properties of materials for energy and information technology, fundamental studies on the reactivity of main group and transition elements, and nanotechnology. Synthetic efforts are directed at hydrogen storage materials and thermoelectrics, catalysts for solar hydrogen generation, fullerenes and metal porphyrins, metal clusters and compounds with element-element bonds, as well as nanowires and nanoparticles.

Adapted for CHEM 250, UBC-V

This course package is designed as an introduction to General and Applied Science. It satisfies the learning outcomes for British Columbia ABE Intermediate General and Applied Science, which is considered an equivalent to BC Science 10. This resource includes powerpoints, class notes, and laboratory manuals for each of three three modules: Chemistry, Biology, and Physics. Throughout these modules, students explore the scientific method, take part in peer discussions, try out their problem solving skills in classroom and laboratory settings, and learn required skills and knowledge to prepare them for the Grade 11 level of science. Quizzes and mini-finals are also available to instructors upon request.

The activity asks students to make observations about what occurs when two effervescent antacid tablets are placed into a beaker of water. The Students work together in groups. There are three parts to the activity. In the first part, the tablets are dropped into tap water and student groups (2-4 students) must complete a series of question sheets (one per group) that guide them through thinking about the event. In the second part, a presentation on chemical equilibrium for the carbonate system is given. The starting point is the answers received in the first part. Basic chemical reactions for the carbonate system are presented including equilibrium expressions for each reaction and discussion about open and closed systems. At the end of class, a handout is given to the students. In the third part, three beakers (acidic, neutral and basic solutions, but not indicated) are placed together and two tablets are placed into each beaker. Students are split into two groups (8-12 students) and are asked to describe why the reactions are different. Discussion follows collection of student responses in each part. Once the chemical reactions and equilibrium expressions are presented, they are involved and referenced in all discussions.

Short Description:
Introduction to Chemistry is designed for a one-term introductory chemistry course. For many students, this course provides their first and what may be their only academic introduction to chemistry. As such, this textbook provides an important opportunity for students to learn some core concepts of chemistry and understand how those concepts apply to their lives and the world around them.

This exercise is designed to familiarize students with some basic crystal structures
The exercise helps students fully understand the nature and significance of ionic bonds and Pauling's second rule
It also builds a bit on Pauling's first rule (radius ratio principle)
It is one of several related activities, all of which are intended to help students understand the nature of ionic crystals

CHE 101
A brief presentation of introductory chemical concepts including atomic structure, the chemical equation, the behavior of gases, the chemistry of solution, and acid-base chemistry.

In this lab, students investigate groundwater flow and water quality within a groundwater well field on the CSU campus. The well field is part of the GroundWater Education and Teaching (GetWET) Observatory south of the Hilton Inn off Centre Drive. Students determine water flow paths and rates as well as measure water quality parameters such as water temperature, pH, electrical conductivity, and dissolved oxygen.

Materials needed for this lab include:

Groundwater equipment: Groundwater well or wells adjacent to a perennial stream.
Water quantity equipment: Electronic water meter, staff, plate, tape, stop watch, and float to measure surface velocity.
Water quality equipment: pH, temperature specific conductance, and dissolved oxygen meters, bailer, and bucket to collect samples.
Other equipment: Map of site showing location of wells and stream.

The main goal of this multi-part field and lab exercise is to introduce students to practical aspects of soil and water geochemistry. Some of the analyses for this lab are conducted in the field using field analytical instruments and rest of the analyses is conducted in a wet chemistry/geochemistry lab. There are several objectives:
1. Learn how to sample water and soil samples in a safe and effective manner
2. Collect basic aqueous chemical parameters in the field
3. Compare field collected data with that obtained using advanced instruments in the laboratory
4. Determine bulk physical and chemical properties of the soils in the lab
5. Determine trace and major element concentrations of the soils in the laboratory
At the end of this exercise students will gain a better appreciation for how soil and water quality is assessed in multiple ways. They are also introduced to basic "tools-of-the-trade" in the environmental geochemistry and also using Excel to make simple and advanced calculations as well as for plotting data. During preparation of lab reports, they are introduced to basic elements of an effective data-based technical paper.

Short Description:
Introductory Chemistry is designed to cover the wide range of topics typically covered in a one-semester chemistry course for non-science majors. This re-mixed textbook is an adaptation of chapters predominantly from three open source chemistry texts- Boundless Chemistry by LumenLearning, Chemistry: Atoms First (2e) by OpenStax, and General Chemistry: Principles, Patterns, and Applications by Salyor Academy. This specific text was created to align with the flow of topics taught in the course Chemistry 1010 at Utah State University.

The goal of this textbook is not to make you an expert. True expertise in any field is a years-long endeavor. Here I will survey some of the basic topics of chemistry. This survey should give you enough knowledge to appreciate the impact of chemistry in everyday life and, if necessary, prepare you for additional instruction in chemistry.

This survey should give you enough knowledge to appreciate the impact of chemistry in everyday life and, if necessary, prepare you for additional instruction in chemistry. Throughout each chapter, I present two features that reinforce the theme of the textbook—that chemistry is all around you. The first is a feature titled, appropriately, “Chemistry Is Everywhere.” Chemistry Is Everywhere” focuses on the personal hygiene products that you may use every morning: toothpaste, soap, and shampoo, among others. These products are chemicals, aren’t they? Ever wonder about the chemical reactions that they undergo to give you clean and healthy teeth or shiny hair? I will explore some of these chemical reactions in future chapters. But this feature makes it clear that chemistry is, indeed, everywhere. The other feature focuses on chemistry that you likely indulge in every day: eating and drinking. In the “Food and Drink App,” I discuss how the chemistry of the chapter applies to things that you eat and drink every day. Carbonated beverages depend on the behavior of gases, foods contain acids and bases, and we actually eat certain rocks. (Can you guess which rocks without looking ahead?) Cooking, eating, drinking, and metabolism—we are involved with all these chemical processes all the time. These two features allow us to see the things we interact with every day in a new light—as chemistry.
