Concept explainers

Thermochemistry

Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.

Exergonic Reaction

The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.

Question

**Properties and Changes of Matter**

This interactive exercise illustrates the differences between physical and chemical changes.

At the top of the page, there are several actions listed which include:
- Carving wood
- Slicing an apple
- Burning wood
- Tearing aluminum foil
- Bleaching skin
- Snow melting
- Frying an egg
- Oxidizing of mercury (Hg)

Below these actions are two delineated boxes labeled:
1. **Physical change** - where you can drag actions that represent a physical change.
2. **Chemical change** - where you can drag actions that represent a chemical change.

**Explanation:**

- **Carving wood** and **slicing an apple** are examples of physical changes as they involve changes in shape or size but do not alter the fundamental composition of the material.
- **Burning wood**, **bleaching skin**, and **frying an egg** are examples of chemical changes because they result in the formation of new substances with different chemical properties.
- **Tearing aluminum foil** and **snow melting** are physical changes; tearing aluminum foil changes its shape, while snow melting changes the state of water from solid to liquid without changing its chemical structure.
- **Oxidizing of mercury (Hg)** is a chemical change as it alters the chemical composition of mercury by forming mercury oxide.

Users are encouraged to drag and categorize each action into the correct box to demonstrate their understanding of physical and chemical changes.

After making their selections, users can click "Submit" to check their answers. There are also "Reset" and "Help" buttons available to aid in the exercise.

A chemistry student must write down in her lab notebook the concentration of a solution of potassium chloride. The concentration of a solution equals the mass of what's dissolved divided by the total volume of the solution. Here's how the student prepared the solution: • The label on the graduated cylinder says: empty weight: 1.55 g • She put some solid potassium chloride into the graduated cylinder and weighed it. With the potassium chloride added, the cylinder weighed 31.436 g. • She added water to the graduated cylinder and dissolved the potassium chloride completely. Then she read the total volume of the solution from the markings on the graduated cylinder. The total volume of the solution was 166.4 mL. What concentration should the student write down in her lab notebook? Be sure your answer has the correct number of significant digits. -1 g.mL x10 × Ś

The laboratory compared the mass of the starting reactants and final products of the combustion reaction. A technician determined the mass of the firewood and oxygen reactants before burning to be 2.72 kg. After the firewood finished burning, the pile of cooled ash that remained had a mass of 0.095 kg. According to the law of conservation of mass, matter is neither created nor destroyed in a chemical reaction. Do the results of the technician’s combustion experiment contradict the law of conservation of mass?

A 15000 L tailings pond at a mine site was analyzed for cadmium contamination. First, a 25.0 mL sample of water was removed from the pond. Then the solution was evaporated to dryness, and 56.1 mg of cadmium was recovered (the identity of the metal was confirmed through other methods). Assuming the water is homogeneously distributed throughout the pond, what is the concentration of cadmium in the tailings pond?
