This Digital Resource has less sophisticated functionality as it was one of the first we developed and is priced to reflect this.
This resource covers the things you need to know and be able to do for the NCEA Level 3 Achievement Standard 91390 (Chemistry 3.4) Demonstrate understanding of thermochemical principles and the properties of particles and substances.
What you'll learn
In this resource you’ll find answers to questions like:
- What is the electron configuration of atoms and ions of the first 36 elements using s, p, d notation?
- What are periodic trends in atomic radius, ionisation energy and electronegativity?
- What is the difference between atomic and ionic radii?
- How do you draw Lewis structures and shapes?
- What are the shapes of molecules and ions?
- What does polarity of molecules mean?
- What are the attractive forces between atoms and ions (covalent bonds and ionic bonds)?
- What is intermolecular attraction due to temporary and permanent dipoles, including hydrogen bonding?
- What are the factors affecting the relative strengths of intermolecular forces?
- What is the evidence for differences in the relative strengths of intermolecular forces?
- How do you apply thermochemical principles to systems involving phase changes?
- What is meant by the transfer of heat between the system and surroundings, and use of specific heat capacity?
- What is Hess's law?
LearnWell Digital resources put the learner at the centre. Using almost any device, students can easily work at a pace that suits them through interactive, scaffolded learning and activities.
