Which of the following situations best describes the chemical weathering process of sedimentary rock? Sedimentary limestone cliffs are battered by strong ocean waves.
Sedimentary limestone is exposed to acid rain at the top of a mountain
Sedimentary sandstone allows water to freeze and thaw inside its cracks.
Sedimentary sandstone is carried away by water along the bedrock of a stream.

Based on the equation and the information in the table, what is the enthalpy of the reaction?

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)

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.
