What is one way forces act on atoms
Forces cause bonds to form.
How are models affected by new evidence
Models are changed if they don't fit new 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 happens at the cathode in an electrolytic cell
Reduction occurs at the cathode in an electrolytic cell.
What does a negative cell voltage mean
The reaction is nonspontaneous.
What kind of cell has a negative cell voltage
Which of the following best describes a galvanic cell
A battery containing a spontaneous redox reaction
Which electrode gets heavier in an electrolytic cell
The electrode where reduction occurs.
Which metal gets coated during electroplating
The cathode gets coated during electroplating.
What volume will 3.12 moles of SF6 gas occupy if the temperature and pressure of the gas are 141 degree celsius and 7.77 ATM
What are the spectator ions
Spectator ions are ions that do not part in a chemical
reaction.
What is the oxidation half-reaction for Mg s plus ZnCl2 aq --- MgCl2 aq plus Zn s
MgCl2 aq plus Zn s is the oxidation half-reaction for Mg s plus
ZnCl2 aq.
All life on earth is ultimately dependent on what
Reduction occurs at which electrode
The electrode that removes ions from solution
In the reaction mgcl2 plus 2koh mgoh2 mgoh2 plus 2kcl if 3 moles mgcl2 are added to 4 moles koh what determined how much mgoh2 is made
Where does reduction occur in an electrolytic cell
