1. directions\nchoose the correct answer for each row.\nidentify each substance as either a compound, element, heterogenous mixture, or homogenous mixture\ncompound element homogenous mixture heterogenous mixture\nbag of nuts and seeds\na drink with ice cubes in it\noxygen (o)\ntable salt (nacl)\nair
Answer
Explanation:
Step1: Define types of substances
A compound is made of two or more different - element atoms chemically bonded. An element is a pure substance made of only one type of atom. A homogeneous mixture has a uniform composition throughout, and a heterogeneous mixture has a non - uniform composition.
Step2: Analyze bag of nuts and seeds
It has different types of nuts and seeds that are not chemically bonded and are visibly distinct, so it is a heterogeneous mixture.
Step3: Analyze a drink with ice cubes
The ice cubes and the liquid are two distinct phases, and the composition is not uniform, so it is a heterogeneous mixture.
Step4: Analyze oxygen
Oxygen is made of only oxygen atoms, so it is an element.
Step5: Analyze table salt
Table salt (NaCl) is made of sodium and chlorine atoms chemically bonded, so it is a compound.
Step6: Analyze air
Air is a mixture of nitrogen, oxygen, carbon - dioxide etc. and has a uniform composition at a given altitude, so it is a homogeneous mixture.
Answer:
Bag of nuts and seeds: Heterogenous Mixture A drink with ice cubes in it: Heterogenous Mixture Oxygen (O): Element Table Salt (NaCl): Compound Air: Homogenous Mixture
