Objective: Particle Diagrams for solids, liquids, gases, atoms, molecules, compounds, and mixtures. Lots of drawing today, get paper, put on thinking hats.

Objective: Particle Diagrams for solids, liquids, gases, atoms, molecules, compounds, and mixtures. Lots of drawing today, get paper, put on thinking hats.
A particle diagram shows the idea of chemical substances in a cartoon sort of way. The diagrams are not realistic in shape, but with some imagination and thinking, you can understand what they are going to show. You need to be aware of these vocabulary words to move forward. Think, or ask now. SOLID – LIQUID – GAS ATOM – COMPOUND – MIXTURE – DIATOMIC ELEMENTS These diagrams will show all seven of these, you need to be able to recognize them, and draw examples of each of these seven.
atoms molecules diatomic elements
These might be CO2 2 kinds of atoms Maybe H2, O2, N2, Cl2, etc. These might be NH3
Particle diagrams show atoms, diatomic elements, or molecules. They can also show phases, depending upon how the particles are arranged in the box. LEFT TO RIGHT: Gas particles don’t touch and “float” in space. Liquids are at the bottom, but not arranged orderly. Solid matter has particles in a very orderly pattern, that does not conform to the shape of the container.
Could this be Ammonia NH3 Carbon Dioxide CO2 Water H20 Methane CH4 Could this be Ammonia NH3 Carbon Dioxide CO2 Water H20 Methane CH4
When 4.0 g hydrogen combines rapidly with 32 grams of oxygen in the air to form into wata, how many grams of this dihydrogen monoxide form?
When 4.0 g hydrogen combines rapidly with 32 grams of oxygen in the air to form into wata, how many grams of this dihydrogen monoxide form? 36 grams of course Matter cannot be created or destroyed in a chemical reaction, or physical change. answer 4.Og + 32g = 36g
What's in the box? • Atoms only • Atoms and molecules • Molecules only • Diatomic elements • A mixture • A compound Which of these could be in the box? H2, He, CO2, H2O, CO, CH4
What's in the box? That is an atom, could be He, or any other single atom. That is a compound with a 1:1 ratio, maybe CO This is a diatomic element, maybe H2 Which of these could be in the box? H2, He, CO2, H2O, CO, CH4
In two boxes below, draw iron in the solid phase at left, and helium in the gas phase at right.
