Context clues practice quiz Grade 12

🧪 Topic Summary

In chemistry, context clues are pieces of information within a text that help you understand the meaning of unfamiliar words, concepts, or reactions. Instead of memorizing every single term, you can use the surrounding information – like the surrounding words, sentences, and the overall topic being discussed – to infer their meaning. This is super useful for understanding complex scientific texts and solving problems!

🔬 Part A: Vocabulary

Match each chemistry term with its correct definition:

1. Term: Catalyst
2. Term: Endothermic
3. Term: Equilibrium
4. Term: Titration
5. Term: Isotope

1. Definition: A reaction that absorbs heat from its surroundings.
2. Definition: Atoms of the same element with different numbers of neutrons.
3. Definition: A substance that speeds up a chemical reaction without being consumed.
4. Definition: The point where the rate of forward and reverse reactions are equal.
5. Definition: A process for determining the concentration of a solution using a solution of known concentration.

Match the term with the correct definition. For example, write 1-A, 2-B, etc.

🌡️ Part B: Fill in the Blanks

Fill in the blanks in the following paragraph using the words provided below.

Words: Acid, Base, pH, Neutralization, Salt

A(n) ______ is a substance that donates protons or accepts electrons, while a(n) ______ is a substance that accepts protons or donates electrons. The ______ scale measures the acidity or alkalinity of a solution. A reaction between an acid and a base is called ______ , and it produces a(n) ______ and water. A solution with a pH of 7 is considered ______.

⚗️ Part C: Critical Thinking

Explain how understanding context clues can help you better understand a complex chemistry research paper. Provide a specific example of a type of information you can gather from surrounding context.
