How is stoichiometry used to calculate amount of product from amount of reactant
The coefficients give the ratio of moles reactant to moles
product.
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.
How do atoms show both unity and diversity
There are relatively few atoms, but they make many
molecules.
What determines the effect of a limiting reagent on the mass of a product
the amount of limiting reagent
What does a negative cell voltage mean
The reaction is nonspontaneous.
Which pairs of half-reactions would have a negative total reduction potential
Silver (Ag) reduced, gold (Au) oxidized.
What branch of chemistry studies the flow of electrons
How does the activity series of metals reflect the stability of metals
The metals highest on the list are the least stable.
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)
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
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
