This disease is caused by legionella bacteria that proliferate in contaminated water supplies. Determine how the physical properties of a solvent are dependent on the number of solute particles present. Each element is classified as a metal, metalloid, or nonmetal, and its state at room temperature is also given.
Create a variety of challenge molecules including cyclic molecules and isomers. In the Feel the Heat Gizmo, create your own hot and cold packs using various salts dissolved in water and different bag materials. Use a variety of real-world lab tests to analyze common food samples in order to determine if the food is a carbohydrate, a protein, or a lipid. Measure the dew point by cooling a bucket of water until condensation forms on the surface. Chemical changes result in the formation of new substances. Students take on the role of an environmental chemist to investigate the source of legionella and use stoichiometry to decontaminate the water supply and remediate the disease outbreak. 1:: individually and collaboratively plan and conduct observational and experimental investigations. Electrons and chemical reactions gizmo answer key worksheet. Construct a DNA molecule, examine its double-helix structure, and then go through the DNA replication process.

Plot both stable and radioactive isotopes on a graph of neutrons vs. protons, and explore how the neutron:proton ratio of stable isotopes changes from lighter to heavier elements. 3:: use models and simulations to visualize and explain the movement of particles, to represent chemical reactions, to formulate mathematical equations, and to interpret data sets. C. Mass number of an element is equal to the sum of number of protons and number of neutrons, Hence, mass number = 5 + 7 = 12. 3. a:: chemical formulas are models used to represent the number of each type of atom in a substance; Chemical Equations. Salt can be added to the water to see its effect on the freezing point of water. E:: colligative properties depend on the extent of dissociation. Tiles can be flipped to cancel units. Data can be interpreted visually using a dynamic graph, a bar chart, and a table. Determine the effects of concentration, temperature, surface area, and catalysts on reaction rates.
