Interpretation:
The initial fragrance, as well as the change in the fragrance over time of the given perfume, is to be identified.
Concept Introduction:
Solid, liquid and gas are the three
When these forces start decreasing, the state changes from solid to liquid. This is termed as melting. On further decrease in the intermolecular forces, liquid changes to a gas. This is termed as vaporization. Some substances bypass the liquid state and directly convert from solid to gas state. This process is known as sublimation.
There is a number of intermolecular forces which play a role in different molecules such as dipole-dipole, hydrogen bonding, and dispersion forces etc.
The compounds lacking specific functional moieties have dispersion forces acting on their molecules. These increase with an increase in the molecular mass.
Lower are the forces of attraction, more is the volatility of the substance.

- If the combination of iron filings and sulfur in Question 25 is heated strongly, the iron reacts with the sulfur to form a solid that is no longer attracted by the magnet. Would this still represent a “mixture”? Why or why not?arrow_forwardWhat is the shiny metallic substance coating that form in the walls of the test tube when mercury oxide is heated? And is the substance element or compound?arrow_forward1. An unknown liquid is added to a beaker of water. After a few minutes you discover that unknown liquid is floating on top of the water in a separate layer. Explain what type of compound the unknown liquid is, and how you know?arrow_forward

- 1. Seawater is composed of salt, sand, and water. Is seawater a heterogenous mixture or homogenous mixture? 2. Suppose there are four unknowns in bottles: three of the bottles are solutions and one is a pure substance. How are you going to determine which of the unknown is a pure substance?arrow_forwardQuestion 2 A chemist observes that solid copper(Il) sulfate crystals do not pass through filter paper. The chemist mixes 2.5 g of the blue crystals with 2 L water to produce a clear, blue liquid. When filtered through filter paper, the filtered liquid retains the same blue color. How can these observations be explained? A Materials pass through filter paper only when the paper is wet. B. The copper sulfate crystals slide more easily through the filter paper when water is present. The copper sulfate reacts with water molecules to form a new substance that can pass through filter paper. Water acts as a solvent to break up copper sulfate into individual ions, which allows them to pass through the filter paper.arrow_forwardA chef in Denver (the mile high city) and a chef in Tampa (sea level city) make the same recipe but the Denver chef has to modify the recipe. Why did the Denver chef have to modify the recipe? O The density of water is higher at high altitudes O The boiling point of water is lower at high altitudes O The boiling point of water is higher at high altitudes O The density of water is lower at high altitudes D Question 9 Which statement describes how food is cooked using microwaves? O The food reflects microwaves causing the air surrounding the food to heat up O Microwaves heat up the air around the food and it is transferred to the food through convection O Microwaves break chemical bonds and the energy that is released cooks the food O The food absorbs the microwaves and its molecules begin to rotate causing heat D Question 10 When making yogurt, the pH of the milk solution O decreases, making it more sour O No answer text provided. O stays the same O increases, making it more bitterarrow_forward
- 1. Give two reasons why one substance might have a greater density than another substance from a molecular point of view. Explain each reasons. 2. What would happen to the water level in a glass if the ice cube floating in a glass of water will be completely melted? 3. Why does a balloon filled with helium gas rise? Is there a lower limit on how much helium gas it must contain before it begins to rise?
