(08.01 MC) Segment Two Exam: Which of the following describes a characteristic of water that helps it in dissolving a wide range of chemicals and bio molecules?
A) It has a partial negative charge on oxygen and a partial positive charge on hydrogen.
B) It has a linear molecular structure with H-O-H arranged in a straight line.
C) It requires a high amount of heat to raise or drop its temperature.
D) It has completely non-polarized O-H bonds.

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.

The activation energy for the reaction no2(g)+co2(g)⟶no(g)+co(g) is ea = 300 kj/mol and the change in enthalpy for the reaction is δh = -100 kj/mol . what is the activation energy for the reverse reaction?
