How is stoichiometry used
Stoichiometry is used to find the molar ratios between the
reactants of a chemical reaction.
What is one way forces act on atoms
Forces cause bonds to form.
Why do scientists define systems
It minimizes sources of bias in the data.
What makes balancing redox reactions different from balancing other reactions
Balancing redox reactions is different from balancing other
reactions because both the number of atoms and the amount of charge
must be balanced.
What does a negative cell voltage mean
The reaction is nonspontaneous.
How do chemists organize information about elements
By grouping the elements on the periodic table
When a magnet is moved alongside a wire what happens
the electrons in the wire begin to flow
Which power source directs these lost electrons through an electronic device to give it power
Which does not state a principle related to why ground wires are in effective safety device
electronic devices are protected from power surges by having insulated wires
Which of the following metals is the least stable Silver Potassium Iron or Aluminum
A particular power source creates electricity through the use of giant magnets that are rotated to create a flow of electrons. This electricity is then directed
From the electric generator to electric outlets in homes
Where does reduction occur in an electrolytic cell
