Use the scenario to answer the next two questions

Making solutions

Solutions are mixtures that are very common in our daily lives. A solution is composed of a solute and a solvent.

A student conducted an investigation using 50 milliliter of distilled water and 5 grams of table salt. The water for each test was brought to a certain temperature before the salt was added. The data from the investigation are shown in the graph.

Which conclusion best describes the data in the graph?

• Increasing the amount of solvent increases the temperature of a solution

• Increasing the temperature of the solute increases the amount of the solution

• the amount of solute in a solution determines the time needed for the solute to dissolve in the solvent

• A decrease in the temperature of a solvent increases the time needed for a solute to dissolve in a solvent

A student needs to separate a mixture compsed of iron fillings and sand. How can the student most easily separate all the iron fillings from the mixture?

• Use a magnet to attract the iron filings

• Use filter paper to isolate the iron filings

• Add water to the mixture and pour off the floating iron filings.

• Add water to the mixture and allow it to evaporate and leave behind the iron filings

Which statement identifies the most likely outcome if the rabbit population suddenly reduced?

• Owls would become extinct because they have no food

• Hawks would have less food available so their population would decrease

• Grasshoppers would have less food available so their population would decrease

• Grasses in the area would die and all of the animals would have to move to another area to survive

The diagram shows what happens when wood is burned

Burning Wood

^{wood + oxygen} = ^{ashes+carbon dioxide gas + water}

^{(starting) ------------------------------ (ending)}

Which statement best explains the change that occurs when wood is burned?

• This is physical change because the products can be changed back into wood

• This is physical change because the products are different from the starting materials

• This is chemical change because the products can be changed back into wood

• This is chemical change because the products are different from the starting materials
