Chapter 1: Problem 82

Classify the following mixtures as homogeneous or heterogeneous. a. potting soil b. White wine c. your sock drawer d. window glass e. granite

Short Answer

Expert verified
a. potting soil - heterogeneous b. White wine - homogeneous c. your sock drawer - heterogeneous d. window glass - homogeneous e. granite - heterogeneous

Step by step solution

01

a. Potting Soil

Potting soil can contain different ingredients such as peat moss, perlite, compost, and vermiculite. These ingredients can be visibly distinguished and don't have a uniform appearance. Therefore, potting soil is a heterogeneous mixture.
02

b. White Wine

White wine is made by fermenting crushed grapes and then filtering out the solid particles. The final product has a uniform appearance and composition, making it a homogeneous mixture.
03

c. Your Sock Drawer

A sock drawer typically contains various types and colors of socks that can be visibly distinguished from one another. Therefore, a sock drawer is considered a heterogeneous mixture.
04

d. Window Glass

Window glass, which is typically made by melting and cooling a combination of silica, soda ash, and limestone at a high temperature, has a uniform composition and appearance. Therefore, window glass is a homogeneous mixture.
05

e. Granite

Granite is a type of rock composed of various minerals such as quartz, feldspar, and mica. Different minerals can be visibly distinguished within the rock, making granite a heterogeneous mixture.

Perform the following mathematical operations, and express each result to the correct number of significant figures. a. \(\frac{0.102 \times 0.0821 \times 273}{1.01}\) b. \(0.14 \times 6.022 \times 10^{23}\) c. \(4.0 \times 10^{4} \times 5.021 \times 10^{-3} \times 7.34993 \times 10^{2}\) d. \(\frac{2.00 \times 10^{6}}{3.00 \times 10^{-7}}\)

Which of the following are exact numbers? a. There are \(100 \mathrm{~cm}\) in \(1 \mathrm{~m}\). b. One meter equals \(1.094\) yards. c. We can use the equation $$ { }^{\circ} \mathrm{F}=\frac{9}{5}^{\circ} \mathrm{C}+32 $$ to convert from Celsius to Fahrenheit temperature. Are the numbers \(\frac{9}{5}\) and 32 exact or inexact? d. \(\pi=3.1415927\).

Sterling silver is a solid solution of silver and copper. If a piece of a sterling silver necklace has a mass of \(105.0 \mathrm{~g}\) and \(\mathrm{a}\) volume of \(10.12 \mathrm{~mL}\), calculate the mass percent of copper in the piece of necklace. Assume that the volume of silver present plus the volume of copper present equals the total volume. Refer to Table \(1.5\). Mass percent of copper \(=\frac{\text { mass of copper }}{\text { total mass }} \times 100\)

Perform the following unit conversions. a. \(908 \mathrm{oz}\) to kilograms b. \(12.8 \mathrm{~L}\) to gallons c. \(125 \mathrm{~mL}\) to quarts d. \(2.89\) gal to milliliters e. \(4.48 \mathrm{lb}\) to grams f. \(550 \mathrm{~mL}\) to quarts

This year, like many past years, you begin to feel very sleepy after eating a large helping of Thanksgiving turkey. Some people attribute this sleepiness to the presence of the amino acid tryptophan in turkey. Tryptophan can be used by the body to produce serotonin, which can calm the brain's activity and help to bring on sleep. a. What mass in grams of tryptophan is in a \(0.25\) -lb serving of turkey? (Assume tryptophan accounts for \(1.0 \%\) of the turkey mass.) b. What mass in grams of tryptophan is in \(0.25\) quart of milk? (Assume tryptophan accounts for \(2.0 \%\) of milk by mass and that the density of milk is \(1.04 \mathrm{~kg} / \mathrm{L}\).)
