What is one way forces act on atoms

Forces cause bonds to form.

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.

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.

What is the average atomic mass of an element with isotopes a b and c

(mass of A) x (%of A) + (mass of B) x (% of B) + (mass of C) x (% of C)

Which metal gets coated during electroplating

Reduction occurs at which electrode

The electrode that removes ions from solution

What is a trend seen in the periodic table

electronegativity

Which of the following metals is the least stable Silver Potassium Iron or Aluminum
