Question

salt barium air orange juice with pulp platinum hot tea silicon salt water carbon monoxide soil toluene element compound heterogeneous mixture homogeneous mixture

Explanation:

An element is a pure substance made of only one type of atom. A compound is made of two or more different - type atoms chemically combined. A heterogeneous mixture has visibly different parts, and a homogeneous mixture has a uniform composition throughout.

• Barium, platinum, and silicon are elements as they consist of only one type of atom.
• Salt is a compound (sodium chloride, NaCl). Carbon - monoxide (CO) is also a compound.
• Orange juice with pulp and soil are heterogeneous mixtures as they have distinct parts.
• Air, hot tea, salt water, and toluene are homogeneous mixtures as they have a uniform appearance.

Answer:

Element: Barium, Platinum, Silicon
Compound: Salt, Carbon monoxide
Heterogeneous mixture: Orange juice with pulp, Soil
Homogeneous mixture: Air, Hot tea, Salt water, Toluene
