Flammability and combustibility are this type of property?
What physical property would be the best to use to tell the difference between powdered sugar and baking soda in your kitchen at home?
If you poured a red liquid, blue liquid and green liquid into a glass and the blue liquid formed a layer on the top of the others, what could you say about its density?
Describe the shape and volume of a liquid.
Most metallic elements have these properties.
This happens to the identity of matter during a chemical change.
Crumpling a piece of paper is a physical change because this physical property is the only thing that changes.
Evidence of a chemical change includes these pieces of evidence.
Baking soda and vinegar combine and gas and water are produced. This is what type of change?
What is evidence that food digesting is a chemical change?
How is the particle motion of a liquid different from the motion of a solid?
Which way does heat transfer between substances?
What happens to the energy of particles when a substance changes from a gas to a liquid?
What are the three ways that heat is transferred?
What happens to the temperature of a substance when it goes through a phase/state change?
Atoms as they appear on the periodic table of elements have this overall charge.
This is located in the nucleus of the atom
The number of valence electrons that arsenic (As) has.
The atomic weight of Cobalt (Co).
Most elements on the periodic table belong to this class.
When electrons are transferred between atoms to form a bond, it is this type of bond that forms.
Covalent bonds form between these classes of elements.
Why noble gasses do not normally form bonds.
