Determine if each item is a chemical or physical change.
Determine if each item is a chemical or physical change.
A reaction is given and each substance is notated as a (s), (l) or (g). Which are products? Which are reactants? Is energy absorbed or released? Is the reaction endothermic or exothermic?
Concepts relating to the father or modern chemistry, Lavoisier, burning, etc.
For the three items given, does kinetic energy increase or decrease?
You are given an octahedral model such as AsF6-. All bonded atoms, no lone pairs. How many atoms are bonded? Are there 2 kinds of
You are given a model of seesaw geometry such as XeO2F2. What kind of atom is missing? Approximate bond angles? Geometry defined by equatorial angles? Name of geometry? Position of O? Position of F?
You are given a picture of a trigonal bipyramidal atom such as XeO3F2. Are all positions the same or two different? Shape of O atoms? Is Xe on the O plane? Are F on the same or opposite side as O? Approximate bond angles? Geometry of equatorial and axial? geometry? Position of O and position of F?
Three hybridizations are given. Match the images given with the correct hybridization and select the electron pair geometry.
Determine if each item is macroscopic, microscopic or particulate.
