(a)
Interpretation:
Whether a beaker that weighs 6.6 g is a qualitative data or quantitative data needs to be determined.
Concept introduction:
Data is the collection of information obtained through observations about a person or a thing. Qualitative data is used for approximates and characterization. Quantitative data has numbers.
Answer to Problem 43A
A beaker that weighs 6.6 g is a quantitative data.
Explanation of Solution
Qualitative data is the measure of types and is mostly represented in the form of name, symbols or number codes. Whereas quantitative data is the measure of values or counts and is expressed in numbers. These are numeric variables representing the quantities as how many, how much or how often.
Thus, a beaker weighing 6.6 g is a quantitative data because it is data of the weight.
(b)
Interpretation:
Whether sugar crystals are white and shiny is a qualitative data or quantitative data needs to be determined.
Concept introduction:
Data is the collection of information obtained through observations about a person or a thing. Qualitative data is used for approximates and characterization. Quantitative data has numbers.
(b)
Answer to Problem 43A
Sugar crystals are white and shiny is a qualitative data.
Explanation of Solution
Qualitative data is the measure of types and is mostly represented in the form of name, symbols or number codes. Whereas quantitative data is the measure of values or counts and is expressed in numbers. These are numeric variables representing the quantities as how many, how much or how often.
Hence, sugar crystals are white and shiny is a qualitative data as it is depicting color of the sugar crystals.
(c)
Interpretation:
Whether fireworks are colorful is a qualitative data or quantitative data needs to be determined.
Concept introduction:
Data is the collection of information obtained through observations about a person or a thing. Qualitative data is used for approximates and characterization. Quantitative data has numbers.
(c)
Answer to Problem 43A
Fireworks are colorful is a qualitative data.
Explanation of Solution
Qualitative data is the measure of types and is mostly represented in the form of name, symbols or number codes. Whereas quantitative data is the measure of values or counts and is expressed in numbers. These are numeric variables representing the quantities as how many, how much or how often.
Hence, fireworks are colorful is the qualitative data.

- Hi!! Please provide a solution that is handwritten. Ensure all figures, reaction mechanisms (with arrows and lone pairs please!!), and structures are clearly drawn to illustrate the synthesis of the product as per the standards of a third year organic chemistry course. ****the solution must include all steps, mechanisms, and intermediate structures as required. Please hand-draw the mechanisms and structures to support your explanation. Don’t give me AI-generated diagrams or text-based explanations, no wordy explanations on how to draw the structures I need help with the exact mechanism hand drawn by you!!! I am reposting this—ensure all parts of the question are straightforward and clear or please let another expert handle it thanks!!arrow_forwardIn three dimensions, explain the concept of the velocity distribution function of particles within the kinetic theory of gases.arrow_forwardIn the kinetic theory of gases, explain the concept of the velocity distribution function of particles in space.arrow_forward
