Chapter 1, Problem 1SAQ

A chemist mixes sodium with water and witnesses a violent reaction between the metal and water. This is best classified as

a) an observation

b) a law

c) a hypothesis

d) a theory

Expert Solution & Answer

Interpretation Introduction

Introduction: The scientific approach to knowledge is empirical and is based on observations and experiments. Most of the observations are quantitative (taking measurements or quantifying something regarding the process) but some of them are qualitative (description of a process) also.

Answer to Problem 1SAQ

(a) The violent reaction witnessed by a chemist on mixing sodium with water is best classified as an observation. Hence, option (a) is correct.

Explanation of Solution

Observation is generally regarded as an act to sense the external real objects.

Theory can be described as a scientific explanation of an observed activity or a phenomenon. It explains the observations or events that are based upon any proven hypothesis.

A law is a description of an observed phenomenon or activity. It is generally regarded as a statement of fact.

A hypothesis is a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.

In this case, there is a violent reaction that is observed. So, it is an observation.

Hello, I am doing a court case analysis in my Analytical Chemistry course. The case is about a dog napping and my role is prosecution of the defendant. I am tasked in the Area of Expertise in Neutron Activation and Isotopic Analysis. Attached is the following case study reading of my area of expertise! The landscaping stone was not particularly distinctive in its decoration but matched both the color and pattern of the Fluential’s landscaping stone as well as the stone in the back of the recovered vehicle. Further analysis of the stone was done using a technique called instrumental neutron activation analysis. (Proceed to Neutron Activation data) Photo Notes: Landscaping stone recovered in vehicle. Stone at Fluential’s home is similar inappearance. Finally, the white paint on the brick was analyzed using stable isotope analysis. The brick recovered at the scene had smeared white paint on it. A couple of pieces of brick in the back of the car had white paint on them. They…
