Which of the following actions will increase the rate of dissolution of a solid solute into an aqueous solution?, Stirring with a spoon, Freezing the solute, Decreasing the temperature, Continuously adding more solute, The image shows two different samples of the same compound, calcium carbonate.There are two beakers full of water. One sample is added to each beaker. Which of the following options correctly compares the rate of dissolution of the samples?, The calcium carbonate stones will dissolve slowly since they have a greater surface area than the calcium carbonate powder., The calcium carbonate stones and calcium carbonate powder will dissolve at the same rate since they have the same surface area., The calcium carbonate stones will dissolve quickly since they have a greater surface area than the calcium carbonate powder., The calcium carbonate stones will dissolve slowly since they have a lower surface area than the calcium carbonate powder., You have a solution of saltwater. Which statement best describes what happens when you perform a dilution by adding water?, The concentration of the solution will increase., The concentration of the solution does not change., The concentration of the solution will decrease., The amount of solute increases., To increase the _________ of a solution, a person would dissolve more _________ into the _________. Which words best complete the sentence?, dilution; solvent; solute, dilution; solute; solvent, concentration; solute; solvent, concentration; solvent; solute, Why does sugar dissolve more slowly in iced tea compared to hot tea?, Ice absorbs sugar more than hot water., Cold water has more molecules that interact with sugar., Cold water molecules move slower and interact with sugar less frequently., Sugar changes its structure in cold solvent., Which of the following best explains why grinding a solid into finer particles increases its rate of dissolution?, It increases the surface area of the solid., It decreases the surface area of the solid., It increases the temperature of the solid., It decreases the temperature of the solvent., A student observes that stirring a solution speeds up the dissolution of a solid. This increase in the rate of dissolution due to stirring is primarily because agitation:, decreases the solvent’s temperature, increases the solute’s surface area, reduces the amount of solvent in contact with the solute, Moves dissolved the solute away from the surface of the solid, allowing more solvent to contact the solid., The images below show two glasses of water at the same temperature, one with a whole tablet and one with a crushed tablet. Which statement best explains why the crushed tablet dissolves faster?, The crushed tablet has a higher temperature., The crushed tablet has a greater surface area exposed to the solvent., The crushed tablet has a smaller mass., The whole tablet absorbs more water., If a student wants to dissolve a solid faster in an aqueous solution, which of the following methods would be least effective?, using hotter water, crushing the solid into a finer powder, using colder water, stirring the solution, A teaspoon of a powdered drink mix is being stirred into a cup of hot water. What factors are affecting the dissolution rate of the drink mix in this scenario?, only temperature, only agitation, Both temperature and agitation., Neither temperature nor agitation.
