Which factor increases the rate of dissolution in an unsaturated solution?
increasing the temperature
decreasing the surface area
decreasing the amount of solute
increasing the amount of solvent

The factor that increases the rate of dissolution in an unsaturated solution is increasing the temperature. The rest of the choices do not answer the question above.

coral.

explanation:

coral. many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing co2 levels and decreasing ph in seawater.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
