HELP!! There are three things that can affect the dissolving process. Describe how each of these can affect how quickly a substance will dissolve. (also known as the rate)
a. Surface area
b. Temperature

c. Agitation (shaking or stirring)

PLEASE HELP

C. Stirring a solute into a solvent speeds up the rate of dissolving because it helps distribute the solute particles throughout the solvent
B.The temperature of the solvent is another factor that affects how fast a solute dissolves. Generally, a solute dissolves faster in a warmer solvent than it does in a cooler solvent because particles have more energy of movement.
A. solute in solid state), temperature and amount of stirring.

m=9

step-by-step explanation:

7m+8=71 subtract   8 from 71 which is 63 than divide it by 7m   equal 9.
