Question 1

A HYPOTHESIS

Answer 1

might be a proposed explanation for a chemical reaction or behavior of a substance. For example, hypothesizing that increasing the temperature will speed up a reaction.

Question 2

A THEORY

Answer 2

might be a proposed explanation for a chemical reaction or behavior of a substance. For example, hypothesizing that increasing the temperature will speed up a reaction.

Question 3

THEORY

Answer 3

well-tested, unifying principle that explains a body
of facts and the laws based on them. Theories can suggest new hypotheses that can
be tested experimentally

Question 4

SCIENTIFIC METHOD INVOLVES

Answer 4

1. Observation: Noticing a chemical phenomenon, like a color change during a reaction.
   2. Question: Asking why this phenomenon occurs.
   3. Hypothesis: Proposing a possible explanation.
   4. Experiment: Conducting experiments to test the hypothesis, such as mixing chemicals under controlled conditions.
   5. Analysis: Analyzing the results to see if they support the hypothesis.
   6. Conclusion: Drawing conclusions based on the data.
   7. Communication: Sharing findings with the scientific community through publications and presentations.

Question 5

QUANTITATIVE INFORMATION

Answer 5

Numerical Data, this includes measurements like concentration, volume, and temperature. For example, measuring the pH of a solution

Question 6

QUALITATIVE INFORMATION

Answer 6

Descriptive data such as the color, smell, or state of a substance. For instance, noting that a solution turns blue when a certain reagent is added.
