Chapter 1: Problem 51

By using estimation techniques, arrange these items in order from shortest to longest: a \(57-\mathrm{cm}\) length of string, a 14 -in. long shoe, and a \(1.1-\mathrm{m}\) length of pipe.

Short Answer

Expert verified
First, convert all measurements to centimeters: the string is already 57 cm, the shoe is \(14 \times 2.54 = 35.56\) cm, and the pipe is \(1.1 \times 100 = 110\) cm. Then, arrange them from shortest to longest: 14-inch shoe (35.56 cm), 57-cm string (57 cm), and 1.1-meter pipe (110 cm).

Step by step solution

01

Decide on a common unit of measurement

In order to arrange the objects in order of their lengths, we must first convert all units to a common unit of measurement. Here, we can convert all the measurements to centimeters since it is the easiest conversion for all given measurements.
02

Convert all lengths to the chosen unit of measurement

We will convert the length of each item to centimeters: 1. The length of a string is already given in centimeters, which is 57 cm. 2. To convert the shoe length from inches to centimeters, we will use the conversion 1 inch = 2.54 cm. Length of the shoe = 14 inches * 2.54 cm/inch = 35.56 cm 3. To convert the pipe length from meters to centimeters, we will use the conversion 1 meter = 100 cm. Length of the pipe = 1.1 meters * 100 cm/meter = 110 cm
03

Arrange the items in order of their lengths

After converting all lengths to centimeters, we have: 1. Length of string = 57 cm 2. Length of shoe = 35.56 cm 3. Length of pipe = 110 cm Now we can easily arrange them from shortest to longest: 1. 14-inch long shoe (35.56 cm) 2. 57-cm length of string (57 cm) 3. 1.1-meter length of pipe (110 cm)

A solid white substance \(\mathrm{A}\) is heated strongly in the absence of air. It decomposes to form a new white substance \(\mathrm{B}\) and a gas \(\mathrm{C}\) The gas has exactly the same properties as the product obtained when carbon is burned in an excess of oxygen. Based on these observations, can we determine whether solids \(\mathrm{A}\) and \(\mathrm{B}\) and the gas \(\mathrm{C}\) are elements or compounds? Explain your conclusions for each substance.

In 2006, Professor Galen Suppes, from the University of Missouri-Columbia, was awarded a Presidential Green Challenge Award for his system of converting glycerin, \(\mathrm{C}_{3} \mathrm{H}_{5}(\mathrm{OH})_{3}\), a by-product of biodiesel production, to propylene glycol, \(\mathrm{C}_{3} \mathrm{H}_{6}(\mathrm{OH})_{2}\). Propylene glycol produced in this way will be cheap enough to replace the more toxic ethylene glycol that is the primary ingredient in automobile antifreeze. (a) If \(50.0\) mL of propylene glycol has a mass of \(51.80 \mathrm{~g}\), what is its density? (b) To obtain the same antifreeze protection requires \(76 \mathrm{~g}\) of propylene glycol to replace each \(62 \mathrm{~g}\) of ethylene glycol. Calculate the mass of propylene glycol required to replace \(1.00\) gal of ethylene glycol. The density of ethylene glycol is \(1.12 \mathrm{~g} / \mathrm{mL}\). (c) Calculate the volume of propylene glycol, in gallons, needed to produce the same antifreeze protection as \(1.00\) gallon of ethylene glycol.

Small spheres of equal mass are made of lead (density \(=11.3 \mathrm{~g} / \mathrm{cm}^{3}\) ), silver \(\left(10.5 \mathrm{~g} / \mathrm{cm}^{3}\right)\), and aluminum \(\left(2.70 \mathrm{~g} / \mathrm{cm}^{3}\right)\). Without doing a calculation, list the spheres in order from the smallest to the largest.

Label each of the following as either a physical process or a chemical process: (a) corrosion of aluminum metal, (b) melting of ice, (c) pulverizing an aspirin, (d) digesting a candy bar, (e) explosion of nitroglycerin.

(a) Classify each of the following as a pure substance, a solution, or a heterogeneous mixture: a gold coin, a cup of coffee, a wood plank. (b) What ambiguities are there in answering part (a) from the descriptions given?
