The independent variables in Part I, the ones intentionally manipulated, are the
A. Mass and type of material
B. Temperature and volume
C. Density and gravity

The independent variable in Part II, the one that is intentionally manipulated, is the
A. Mass
B. Type of material
C. Temperature

The dependent variable for both Parts I and II, the one that you measure the response in, is the
A. Mass
B. Type of material
C. Temperature

What is the overall order of reaction for rate = k[no]2[o2]

Astable electron arrangement for an atom is one that does not easily change. how is this arrangement arrived at? a. valence electrons are transferred or shared to create a full outer shell of electrons. b. valence electrons are discarded into space to create a full outer shell of electrons. c. protons (positive charge) pair with valence electrons (negative charge) to create a strong bond. d. outer shells with valence electrons are transferred or shared.

To find the enthalpy of a reaction in the lab, you measured the of the reactants and the change during the reaction.
