Assigning virtual experiments as pre-lab assignments is an effective way to promote conceptual understanding and enable students to be both minds-on and hands-on when in physical lab. From osmosis, diffusion, pH balance, to spectrophotometry, discover how 91视频 Hill Virtual Labs for Chemistry can support your student鈥檚 hands-on work.
Students will separate an unknown mixture containing two miscible liquids and separate it into its components. Using simple distillation and fractional distillation, students use the same unknown mixture to determine each liquid component's boiling point and identity.
Using Simple and Fractional Distillation to Separate Binary Liquid Mixture
Students will use Lewis structures and VSEPR theory to predict shapes of small molecules and polyatomic ions.
Molecular Modeling
Students will observe indications of a chemical change after mixing aqueous solutions or adding a metal to an aqueous solution. Students will classify the chemical reaction and identify the net ionic equation.
