Question

Classify each of the following substances as an element, compound or mixture:
\begin{tabular}{lll} 
sea water & hydrogen & honey \
magnesium oxide & copper(II) sulfate & blood \
calcium & mud & potassium iodide solution
\end{tabular}

Accepted Answer

∻Solution∻ ‖ 1 ⋮ **Classify sea water**: Sea water is a mixture of water, salts, and various other substances. It does not have a fixed composition. ‖‖ 2 ⋮ **Classify hydrogen**: Hydrogen is an element, represented by the symbol H on the periodic table. ‖‖ 3 ⋮ **Classify honey**: Honey is a mixture of sugars, water, and other compounds, making it a mixture. ‖‖ 4 ⋮ **Classify magnesium oxide**: Magnesium oxide is a compound formed from magnesium and oxygen, with the formula $MgO$. ‖‖ 5 ⋮ **Classify copper(II) sulfate**: Copper(II) sulfate is a compound with the formula $CuSO_4$, consisting of copper, sulfur, and oxygen. ‖‖ 6 ⋮ **Classify blood**: Blood is a complex mixture containing cells, proteins, and other substances, thus classified as a mixture. ‖‖ 7 ⋮ **Classify calcium**: Calcium is an element, represented by the symbol Ca on the periodic table. ‖‖ 8 ⋮ **Classify mud**: Mud is a mixture of water and various particles, making it a mixture. ‖‖ 9 ⋮ **Classify potassium iodide solution**: Potassium iodide solution is a mixture of potassium iodide ($KI$) dissolved in water, thus classified as a mixture. ‖ ∻Answer∻ ⚹ Sea water: Mixture ⚹ ⚹ Hydrogen: Element ⚹ ⚹ Honey: Mixture ⚹ ⚹ Magnesium oxide: Compound ⚹ ⚹ Copper(II) sulfate: Compound ⚹ ⚹ Blood: Mixture ⚹ ⚹ Calcium: Element ⚹ ⚹ Mud: Mixture ⚹ ⚹ Potassium iodide solution: Mixture ⚹ ∻Key Concept∻ ⚹ Classification of substances into elements, compounds, and mixtures ⚹ ∻Explanation∻ ⚹ Elements are pure substances made of one type of atom, compounds are made of two or more elements chemically combined, and mixtures contain two or more substances that are not chemically bonded◊What is the chemical formula for potassium iodide?⍭ Generate me a similar question◊⚹
