Question

Classify the following as an element, a compound, a solution, or a heterogeneous mixture: aluminum carbon dioxide sugar and water sulfuric acid an orange a pencil nitrogen gasoline raisin bread water sulfur mercury water & instant coffee carbon particles & sugar air grain alcohol a) Element, Compound, Solution, Heterogeneous Mixture b) Compound, Solution, Element, Heterogeneous Mixture c) Solution, Element, Compound, Heterogeneous Mixture d) Heterogeneous Mixture, Compound, Solution, Element

Answer 1

c) Solution, Element, Compound, Heterogeneous Mixture

Step-by-step explanation:

Aluminum is an element, carbon dioxide is a compound, sugar dissolving in water forms a solution, sulfuric acid is a compound, an orange is a heterogeneous mixture (comprising various components like pulp and peel), a pencil is made of the element carbon, nitrogen is an element, gasoline is a heterogeneous mixture, raisin bread is a heterogeneous mixture, water and sulfur together form a heterogeneous mixture, mercury is an element, water and instant coffee form a solution, carbon particles and sugar form a heterogeneous mixture, air is a homogeneous mixture (a solution of gases), grain alcohol is a solution, and finally, carbon particles and sugar in the air constitute a heterogeneous mixture.

In summary, the classification is based on the nature of substances and their combinations. Elements are fundamental substances, compounds are composed of different elements in fixed ratios, solutions involve a homogenous mixture of substances, and heterogeneous mixtures have distinguishable components. This classification system allows us to understand the diverse nature of materials and their interactions in various forms.
