Question

this is a brass trumpet. brass is a shiny metal. to make brass, copper and zinc metals are melted down and mixed together until they are evenly distributed. yellow brass, which consists of about 70% copper and about 30% zinc, is used to make trumpets that produce a bright, forceful sound. gold brass, which has a higher percentage of copper, produces a richer, fuller sound. classify brass. element compound homogeneous mixture heterogeneous mixture

Explanation:

Step1: Define element, compound, homogeneous mixture, heterogeneous mixture

• Element: A pure substance consisting of only one type of atom.
• Compound: A pure substance formed by chemically combining two or more elements in a fixed ratio.
• Homogeneous mixture: A mixture with a uniform composition throughout.
• Heterogeneous mixture: A mixture with a non - uniform composition.

Step2: Analyze brass composition

Brass is made by melting and mixing copper and zinc metals until evenly distributed. It is not a pure element (has two metals) or a compound (no chemical reaction to form a new substance with fixed ratio in the sense of a compound formula). Since the copper and zinc are evenly distributed, it is not a heterogeneous mixture.

Answer:

homogeneous mixture
