What is the theoretical yield of a reaction
The amount of product that is possible in a 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.
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.
How do atoms show both unity and diversity
There are relatively few atoms, but they make many
molecules.
What is true of both galvanic and electrolytic cells
reduction happens at the cathode
Oxidation happens at the anode
What happens to the anode in an electrochemical cell
What happens at the cathode in an electrolytic cell
Reduction occurs at the cathode in an electrolytic cell.
Why is the average atomic mass used when calculating grams of a substance
the elements in the substance are mixtures of their isotopes
Which of the following best describes a galvanic cell
A battery containing a spontaneous redox reaction
All life on earth is ultimately dependent on what
Similar scientific themes are seen in what areas of science
If an element has three isotopes with known masses what information is needed to find the average atomic mass of the element
The abundance percentage of each isotope
In the reaction MgCI2 plus 2KOH MgOH2 plus 2KCI how many moles of MgOH2 are produced for every mole of MgCl2
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
In the reaction mgcl2 plus 2koh mgoh2 plus 2kcl how many moles of koh react with 1 mole of mgcl2
