How is stoichiometry used

Stoichiometry is used to find the molar ratios between the reactants of a chemical reaction.

How is stoichiometry used to calculate the amount of product produced

Stoichiometry relates moles of reactant to moles of product, so if you have the amount of reactant in the equation, you can calculate the amount of product produced.

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.

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 is true of both galvanic and electrolytic cells

reduction happens at the cathode

Oxidation happens at the anode

What happens at the cathode in an electrolytic cell

Reduction occurs at the cathode in an electrolytic cell.

Which of the following best describes a galvanic cell

A battery containing a spontaneous redox reaction

Which metal gets coated during electroplating

The cathode gets coated during electroplating.

Similar scientific themes are seen in what areas of science

In all areas of science

What is a trend seen in the periodic table

electronegativity

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

Potassium.

Which of the following statements describes electromagnetism

Magnetism can create electricity, and electricity can create magnetism.
