Balancing a chemical equation involves a certain amount of trial and error. In general, however, you should follow these steps: Count each type of atom in reactants and products. Does…

Acids and bases react with one another to yield two products: water, and an ionic compound known as a salt. This kind of reaction is called a neutralization reaction. All alkalis are…

Describe how common tools (pH meter, conductivity, pH paper) help identify whether a solution is an acid or base and strong or weak and concentrated or dilute.....

Describe the relationships between volume and amount of solute to solution concentration. Explain how solution color and concentration are related. Predict how solution concentration will change for any action (or…

Describe and draw models for common static electricity concepts (transfer of charge, induction, attraction, repulsion, and grounding). Make predictions about force at a distance for various configurations of charge. ......

Explore how light interacts with molecules in our atmosphere. Identify that absorption of light depends on the molecule and the type of light......

Define “isotope” using mass number, atomic number, number of protons, neutrons and electrons. Given information about an element, find the mass and name of an isotope.

Describe the qualitative difference between scattering off positively charged nucleus and electrically neutral plum pudding atom. For charged nucleus, describe qualitatively how angle of deflection depends on: Energy of incoming…

Relate the electrostatic force magnitude to the charges and the distance between them. Explain Newton's third law for electrostatic forces.......
