Bio Chapter 2 - The Cell

Solvent

________- A liquid that is able to dissolve a solid.

Proton

________- a positive charge inside the atom and bonded to neutrons.

Electron

________- a negative charge on the outside of an atom.

Solute

________- A substance that is dissolved in a solution.

Neutron

________- no charge and inside of the atom.

Solution

________- A type of homogenous mixture in which the particles of one or more substances (the solute) are distributed uniformly throughout another substance (the solvent)

oxygen atom

However, the ________ has more protons in its nucleus (which are positive) and therefore attracts more electrons (making it negative), although the hydrogen keeps some (making it positive)

Cohesion

________- The act of water sticking to itself.

Adhesion

________- The act of water sticking to other surfaces.

Polar Covalent Bond

________- These are formed when there is an unequal sharing of electrons between atoms.

Compound

________- consisting of two or more simple parts or individuals in combination.

Covalent Bond

________- These are formed when there is an equal sharing of electrons between atoms.

Capillary Action

________- The act of water using both cohesion and adhesion to supply water to the leaves of a plant.

Polar Molecule

Why is Water a(n) ________- Water is polar because the hydrogen and oxygen atoms share electrons.

Electron

a negative charge on the outside of an atom

Neutron

no charge and inside of the atom

Proton

a positive charge inside the atom and bonded to neutrons

Compound

consisting of two or more simple parts or individuals in combination

What is the compound H2SO4 made of

two hydrogen atoms, one sulfur atom, and four oxygen atoms

Why Does Ice Float

Ice floats because when it freezes, it expands and binds to other water molecules doing the same

Adhesion

The act of water sticking to other surfaces

Cohesion

The act of water sticking to itself

Capillary Action

The act of water using both cohesion and adhesion to supply water to the leaves of a plant

Surface Tension

Tension created by tension inflicted upon the bonds of water molecules

Differences

Water sticking to itself versus other surfaces, water using this to perform an action, and the use of cohesion in surface tension

Polar Covalent Bond

These are formed when there is an unequal sharing of electrons between atoms

Covalent Bond

These are formed when there is an equal sharing of electrons between atoms

Why is Water a Polar Molecule

Water is polar because the hydrogen and oxygen atoms share electrons

Solution

A type of homogenous mixture in which the particles of one or more substances (the solute) are distributed uniformly throughout another substance (the solvent)

Solute

A substance that is dissolved in a solution

Solvent

A liquid that is able to dissolve a solid
