In the case of H20, the oxygen atom covalently bonds unequally with 2 hydrogen atoms. This is why H20
is considered a _______ molecule. - polar
Electrons are not evenly distributed; at any instant, they may accumulate by chance in one part of a
molecule or another, causing every-changing regions of positive and negative charge that enable all
atoms and molecules to stick to one another, known as - Van der Waals interactions.
Which statement is true of all atoms that are anions? - The atom has more electrons than
protons.
What is negative feedback? - Accumulation of the end product slows its production.
What is an example of positive feedback? - The increasing labor contractions of childbirth before
delivery.
Which of these is reflective of the hierarchical organization of life from most to least inclusive? -
kingdom, phylum, class, order, family, genus, species
A controlled experiment is one in where - there are at least two groups, one of which does not
receive the experimental treatment.
A substance that cannot be broken down into other substances by ordinary chemical procedures is a(n) -
element.
A substance that consists of two or more substances in a fixed ratio is a - compound.
Which of the following subatomic particles always has a positive charge? - proton
, Subatomic particles that have no electrical charge and are located in the atomic nucleus are -
neutrons
Two atoms of an element that differ in number of neutrons are - isotopes.
Isotopes of an element are similar in the sense that they have the same - number of protons.
Isotopes of an element differ in the sense that they have a different - number of neutrons.
A sharing of a pair of valence electrons by two atoms is referred to as a - covalent bond.
Atoms that have an *equal* sharing of a pair of valence electrons is called a - nonpolar covalent
bond.
What is positive feedback? - An end product speeds up its own production.
Atoms that have an *unequal* sharing of a pair of valence electrons is called a - polar covalent
bond.
Energy that matter possess due to location or its structure is known as - potential energy.
When a cation and anion are attracted to each other, this is known as a(n) - ionic bond.
The attraction between a hydrogen covalently bonded to one electronegative atom and another
electronegative atom is called a - hydrogen bond
Capacity to cause change is known as - energy
Example of potential energy? - Molecule of glucose.
