Concept explainers
Interpretation:
The measurement which is not quantitative for pencil should be selected.
Concept introduction:
The measured data which can be reported in numbers is said to be quantitative measurement. These measurements are made with the help of instruments like thermometer, balances, rulers etc.

Answer to Problem 11STP
The correct option is (c), color.
Explanation of Solution
Reason for correct option:
The color is not quantitative measurement for pencil as there are no numbers involved in the measurement of color. It is a qualitative measurement that is for this kind of measurement senses are used to observe the results these are not measurable.
Reason for incorrect options:
Length, mass and diameter are quantitative measurement for pencil as there are numbers involved in the measurement and instrument used for these measurements are scale, balance and caliper micrometer ruler respectively.

Note for advanced students: by significant, we mean that the rate of elimination would be greater than the rate of competing substitution reactions. yes O no If you said elimination would take place, draw the major products in the upper drawing area. If you said elimination would take place, also draw the complete mechanism for one of the major products in the lower drawing area. If there is more than one major product, you may draw the mechanism that leads to any of them. Major Products:arrow_forwardDraw one product of an elimination reaction between the molecules below.
