Question

directions: read the passage, then answer the questions that follow. sugary fruit drink casey wants to make a sugary fruit drink. she has a package of white powder. casey puts the white powder into a glass of water. the pictures show how the powder looked before and after being stirred. 6. explain whether the contents of the glass are solution, mixture, or alloy. write your answer on the lines. 7. casey allows the water to evaporate. read each statement. write your answer. describe what will be left after the water in the glass evaporates. identify how the quantities of water and powder in the glass change.

Explanation:

A solution is a homogeneous mixture where one substance (solute) is dissolved in another (solvent). Here, the white - powder (solute) is dissolved in water (solvent) after stirring, creating a homogeneous mixture. An alloy is a mixture of metals or a metal and other elements, which is not the case here. A mixture can be homogeneous (solution) or heterogeneous. Since the powder dissolves in water to form a uniform mixture, it is a solution. When the water evaporates, the powder (solute) that was dissolved in the water will be left behind. The quantity of water decreases as it evaporates, while the quantity of powder remains the same in terms of mass (assuming no chemical reactions), but its concentration in the remaining substance increases as the water volume decreases.

Answer:

1. The contents of the glass are a solution. The white powder dissolves in water to form a homogeneous mixture.
2. After the water evaporates, the powder that was dissolved in the water will be left behind. The quantity of water decreases as it evaporates, and the quantity of powder remains the same in mass but its concentration relative to the remaining substance increases.
