matter classification worksheet\nall matter can be classified as either a substance or mixture. a substance is an element or a compound. a mixture is heterogeneous or homogeneous.\n\nclassify each of the following as either substance or mixture. if it is a substance, write element or compound in the appropriate column. if it is a mixture, write heterogeneous or homogeneous in the appropriate column. be ready to defend your answer!!!\n\n| type of matter | substance | mixture |\n|--|--|--|\n| chlorine (cl₂) | | |\n| water (h₂o) | | |\n| lucky charms | | |\n| salt water | | |\n| nitrogen (n₂) | | |\n| salt (nacl) | | |\n| rocky road ice cream | | |\n| rubbing alcohol | | |\n| pure air | | |\n| iron (fe) | | |
Answer
Explanation:
Step1: Recall definitions
An element is a pure - substance made of only one type of atom. A compound is a pure - substance made of two or more different types of atoms chemically combined. A homogeneous mixture has a uniform composition throughout, and a heterogeneous mixture has a non - uniform composition.
Step2: Analyze Chlorine ($Cl_2$)
Chlorine ($Cl_2$) is a substance and an element as it is made of only chlorine atoms.
Step3: Analyze Water ($H_2O$)
Water ($H_2O$) is a substance and a compound as it is made of hydrogen and oxygen atoms chemically combined.
Step4: Analyze Lucky Charms
Lucky Charms is a mixture and heterogeneous as it has different components (marshmallows, cereal pieces) that are not uniformly distributed.
Step5: Analyze Salt water
Salt water is a mixture and homogeneous as the salt is uniformly dissolved in the water.
Step6: Analyze Nitrogen ($N_2$)
Nitrogen ($N_2$) is a substance and an element as it is made of only nitrogen atoms.
Step7: Analyze Salt ($NaCl$)
Salt ($NaCl$) is a substance and a compound as it is made of sodium and chlorine atoms chemically combined.
Step8: Analyze Rocky road ice - cream
Rocky road ice - cream is a mixture and heterogeneous as it contains ice - cream, nuts, and marshmallows which are not uniformly distributed.
Step9: Analyze Rubbing Alcohol
Rubbing alcohol is a mixture and homogeneous as it is a solution of isopropyl alcohol and water.
Step10: Analyze Pure air
Pure air is a mixture and homogeneous as it is a mixture of nitrogen, oxygen, and other gases uniformly distributed.
Step11: Analyze Iron (Fe)
Iron (Fe) is a substance and an element as it is made of only iron atoms.
