What can be done to make a solid solute dissolve faster in a liquid solvent? A. decrease the surface area of the solute
B. increase the surface area of the solute
C. decrease the temperature of the solvent

a. a primary source combines several different accounts of an event. b. a primary source generally benefits from having been written after an event.

explanation:

what is the volume occupied by 40 grams of argon gas (ar) at standard conditions? what volume, in liters, is occupied by 1.5 x 1023 

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.
