Chapter 1, Problem 7A

Interpretation Introduction

Interpretation: Two situations needs to be discussed which can analyze a problem. The suggested hypothesis and method to test those hypotheses needs to be explained.

Concept introduction: Chemistry is the science of atoms/molecules and their transformations. Every matter is made of chemicals; the importance of chemistry is that it is the study of everything.

Answer to Problem 7A

Two situations are:

• Brainstrom
• Clarifying the problem.

Explanation of Solution

Chemistry is not something that can simply be memorized. Problem-solving skills are the standard expression of human thinking. Ability to solve a problem is important in every field of study, not just in chemistry. Problem-solving skills involve analytical, mental, and critical thinking skills to reach to the solutions. Understanding how to set up the problem is just as important as the process.

The hypothesis is a specific, testable prediction. It elaborates, in concrete terms, what a person (or chemist) expects will happen in a certain circumstance. After observations are completed, based on those observations, a hypothesis is created and then experiments are conducted. If the hypothesis turns out to be true, based on the experiments, the hypothesis can become a theory. According to this, hypothesis is based upon the observation made.

Two situations are:

• Brainstorm: Students have to keep themselflaser focused on one specific cause and effect theory.
• The nature of problems: In situation students have to understand the process of problem solving. It includes analyzing the information, gathering information, and making decisions based on certain problem.
• Analyzing the data: While write the data by conducting an experiment, be careful and also, communicate accurate results. Being able to solve question allows one to get solution to that question. For example, knowing what units’ variables need to be for equations.

Brainstorm is most suggested hypotheses. A hypothesis test is a statically technique used to make any decision about conjectured value of parameters. Students can make their decision based on experiential or observed values of a test statistic and resulting p-value.

Conclusion

While solving a problem, knowledge of subject or equation to solve first is extremely important.
