New Mastering Science Workbook 2b Answer Chapter 9 -
A typical question in Chapter 9 that students struggle with might look like this:
Question: "In the circuit shown, one bulb burns out but the others remain lit. Is this a series or parallel circuit?"
The Answer Key says: Parallel.
How to understand it (The Logic):
By understanding the logic behind the answer key, you are preparing yourself for the exam, where the question might be flipped: "Why did all the lights go out in this circuit?"
| Concept | Formula | Example (from workbook) | Answer | | :--- | :--- | :--- | :--- | | Ohm’s Law | V = I × R | 6V, 3Ω → I = ? | 2 A | | Power (Electrical) | P = V × I | 220V, 0.5A → P = ? | 110 W | | Energy (Joules) | E = P × t (s) | 100W bulb for 120s | 12,000 J | | Energy (kWh) | E (kWh) = P (kW) × t (h) | 2kW heater for 0.5h | 1.0 kWh | | Cost | Cost = kWh × rate | 1.0 kWh × $1.5 | $1.50 |
Example Question: A 12V battery is connected to a 4Ω resistor. What is the current? Formula: ( V = I \times R ) → ( I = V / R ) Solution: [ I = \frac12V4\Omega = 3A ] Answer: 3 Amperes.
Common Mistake: Forgetting to convert units (e.g., mA to A). Always check!

The New Mastering Science Workbook 2B Chapter 9 focuses on Common Acids and Alkalis. Based on student resources and teacher guides from Oxford University Press and Scribd, the chapter covers the properties, safety precautions, and real-world applications of these substances. Chapter 9: Key Content Overview
The workbook exercises typically test knowledge in the following areas:
Properties of Acids and Alkalis: Identifying substances by taste (sour for acids, bitter for alkalis) and their effects on indicators like litmus paper, red cabbage, and rose petals.
The pH Scale: Using universal indicators and pH meters to measure acidity and alkalinity. A typical question in Chapter 9 that students
Safety and Handling: Critical precautions such as wearing safety goggles and gloves, and the proper technique for diluting concentrated sulfuric acid (adding acid to water gradually). Neutralization Applications: Practical examples include:
Toothpaste: Slightly alkaline to neutralize mouth acids and prevent decay.
Antacids: Alkaline substances used to relieve stomach aches caused by excess acid.
Soil Regulation: Using lime (alkaline) to treat acidic soil. Review of Answer Resources
Educators and students find these answer keys helpful for verifying structured questions and multiple-choice exercises. Key resources include:
Sectional Exercises: These provide true/false and multiple-choice questions that reinforce core concepts.
Spelling Corners: Some guides include vocabulary checks for terms like "Indicator," "Neutralization," and "Corrosive".
Diagram Labeling: Exercises often require labeling scientific setups, such as experiments involving the pH change when hydrochloric acid is mixed with an alkali. Question: "In the circuit shown, one bulb burns
