HONORS CHEMISTRY PRACTICE TEST FINAL 1
FINAL PAPER 2026 SOLVED QUESTIONS AND
FULL SOLUTION UPDATED
◉ how to determine the limiting reactant.
Answer: find the moles (or grams) of product that each could
produce (you must find the same product); whichever one produces
fewer moles (or grams) of product is the limiting reactant
◉ how to find the amount of excess reactant remaining.
Answer: find the amount of excess reactant used by the limiting
reactant; subtract that amount from the original amount of the
excess reactant
◉ theoretical yield.
Answer: the maximum amount of product which can be produced
from a given amount of reactant (calculated from the balanced
equation using stoichiometry)
◉ actual yield.
Answer: the amount of product actually produced when an
experiment is performed (determined experimentally; given in a
problem)
,◉ percent yield formula.
Answer: (actual/theoretical) x 100
◉ energy.
Answer: the capacity to do work or produce heat
◉ first law of thermodynamics.
Answer: energy can be transferred from one form to another but not
created or destroyed (the energy of the universe is constant)
◉ potential energy.
Answer: energy due to position or composition
◉ kinetic energy.
Answer: energy due to the motion of an object
◉ kinetic energy formula.
Answer: (1/2)mv^2
◉ state functions.
Answer: a property that depends only on its present state
, ◉ temperature.
Answer: a measure of the random motions of the particles in a
substance; the average kinetic energy of the particles
◉ thermal energy.
Answer: the total kinetic energy of all of the particles
◉ heat.
Answer: the flow of energy due to a temperature difference
◉ heat flow.
Answer: flows from hotter to colder and stops when it reaches
thermal equilibrium
◉ exothermic energy.
Answer: energy (q) flows out of the system resulting in the
production of heat; the energy of the system is transferred to the
surroundings; q is negative
◉ endothermic energy.
