Question 1 A)Which substance is an example of a nonpolar compound?(1 point) Responses vegetable oil vegetable oil water water food coloring food coloring sugar sugar Question 2 A)Which option is a microscopic property that helps determine whether or not two substances will dissolve with each other? (1 point) Responses volume volume polarity polarity molecular mass molecular mass state of matter state of matter Question 3 A) Use the graph to answer the question. Which statement is the best explanation for the graph? (1 point) Responses As temperature rises, the space between liquid particles decreases, leaving less room for gas particles. As temperature rises, the space between liquid particles decreases, leaving less room for gas particles. As temperature rises, gas particles are moving faster and are more likely to enter the solution. As temperature rises, gas particles are moving faster and are more likely to enter the solution. As temperature rises, gas particles are moving faster and may leave the solution. As temperature rises, gas particles are moving faster and may leave the solution. As temperature rises, the space between liquid particles increases, allowing more room for gas particles. As temperature rises, the space between liquid particles increases, allowing more room for gas particles. Question 4 A)A mother finds her daughter’s mug of hot cocoa on a table an hour after she had been drinking it. As the mother pours out the cocoa, she sees brown solids in the bottom of the mug. How can this be explained?(1 point) Responses This would only happen if too much cocoa powder was added in the first place, because the solubility should not change. This would only happen if too much cocoa powder was added in the first place, because the solubility should not change. All dissolved substances will come out of solution over time. If the mother waits long enough, then all of the powder will appear at the bottom of the mug. All dissolved substances will come out of solution over time. If the mother waits long enough, then all of the powder will appear at the bottom of the mug. The cocoa was mixed with hot water, but some cocoa settled as it cooled because the solubility went down. The cocoa was mixed with hot water, but some cocoa settled as it cooled because the solubility went down. The cocoa was mixed with hot water, but some cocoa settled as it cooled because the solubility went up. The cocoa was mixed with hot water, but some cocoa settled as it cooled because the solubility went up. Question 5 A)After which action would the concentration of a solution remain constant?(1 point) Responses adding water to the solution adding water to the solution removing solution from the container removing solution from the container adding solute to the solution adding solute to the solution evaporating water from the container evaporating water from the container
