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.

The balanced reaction that describes the reaction between hydrogen and oxygen to produce water is expressed 2H2 + O2 = 2H2O. Hence for each mole of oxygen used, two moles of hydrogen is used and two moles also of water is produced.
