That explains the molecular polarity best

Chemistry (ABU)

Vocational high school: Basic skills at the end of grade 12

  • The students differentiate the material level from the particle level by describing observations on the material level and interpreting them on the particle level.
  • Using the periodic table, they describe the structure of molecular substances from molecules and the structure of salts from ions. They also use the periodic table to explain the formation and, conversely, the discharge of ions using the donor-acceptor concept.
  • They characterize molecules on the basis of certain structural features (e.g. bond polarity, molecular polarity, functional group) and assign them to substance classes.
  • They explain physical properties (including boiling temperature, melting temperature, solubility) of molecular substances and salts with the interactions between the particles (molecules, ions) that make up the substances.
  • They use models to explain the structure of matter, the material properties, the bonding relationships and reactions at the particle level. In addition to special features, you also recognize the limits of the models used.
  • They apply rules for the systematic naming of substances and derive statements on their reaction behavior from the structural features of the substances. They describe changes in chemical reactions with energy diagrams and reaction equations, which they also derive from partial equations. They use different formulas and use size equations to carry out simple calculations of the metabolic rate.
  • They explain chemical reactions with substances that are important in everyday life and technology by applying the donor-acceptor concept to acid-base reactions and redox reactions. They justify the incomplete conversion of the substances used with the reversibility of chemical reactions.
  • They use reaction mechanisms to explain the course of organic reactions step by step and to make predictions about possible reaction products.
  • They formulate quantitative statements on the speed of chemical reactions and use them to characterize the state of chemical equilibrium in reversible chemical reactions.
  • You use the equilibrium concept to formulate quantitative statements about the strength of acids and bases and use calculations to prove the effect of acids and bases on the pH value in aqueous solutions.
  • They know the hazard potential of chemicals and deal appropriately with hazardous substances in the laboratory and in everyday life. You dispose of pollutants properly and thereby develop responsibility for protecting your own health and the environment.
  • You plan scientific examinations and carry them out safely. They use scientific working techniques and document, evaluate and visualize the collected data largely independently.
  • With the help of specialist sources (e.g. reference works, non-fiction books, the Internet), the students research chemical issues, interpret the content presented and present the information recorded in correct technical language in a way that is appropriate for the target group.
  • When it comes to chemical issues relating to the environment, the pupils decide between given options for action and indicate which aspects (e.g. ecological, economic) they take into account when making a decision.
