The balanced chemical reaction equation in stoichiometry is used to..?

a) Determine the number of moles and their relationships between reactants and products
b) Determine the mass of each product and calculate percent yield
c) Determine the Limiting reactant based on which substance you have the most of
d) None of the above

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible? a. attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly. b. collisions between gas particles are elastic; there is no net gain or loss of kinetic energy. c. gases consist of a large number of small particles, with a lot of space between the particles. d. gas particles are in constant, random motion, and higher kinetic energy means faster movement.

Identify a specific example for each type of technology

Precision can be defined as the o exact center of a data set. o reproducibility of a measured value. o correlation between two variables that are measured in a data set agreement between a measured value and an accepted value.
