A molecule having four total electron groups around the central atom has three bonding electron groups and one nonbonding electron group what is its molecular structure
How is the oxidation state of a transition metal determined from the chemical formula
The subscript of the second ion identifies the oxidation state
of the transition metal
What would cause the shape of a molecule to be tetrahedral
Four atoms bound to a central atom with no lone pairs
What makes atoms spread out around a central atom
the shared valence electron pairs repel each other.
What best describes a bond formed between two unlike atoms
The type of bond is determined by the difference in
electrongativity of atoms
How does the shape of a molecule affect the polarity of the molecule
C.A molecule that has a symmetrical shape will be a nonpolar
molecule.
How are oxidation states of transition metals indicated in the names of metal compounds
Roman numerals are used to indicate oxidation states.
What determines the ratio of ions in an ionic compound
C.The charges on the ions
What is an example of food engineering
The development of irrigation.
What happens in a double replacement reaction
In this reaction a change of bonds of the reactants occur: the general form is:
AB + CD = AD + BC
How does a lone pair contribute to the molecular shape
The lone pair repels the electrons of the adjacent bonds more so
than does a bonding pair of electrons, so thus alters the molecular
geometry of the molecule.
Which of the following is the correct formula for aluminum oxide
Which of the following could be considered a benefit of modern farming techniques
The food we eat is fresher because it is treated with preservatives.
