Question

02 question (3 points) use the particulate representations of matter a through i in the figure to answer the following questions. 4th attempt part 1 (1 point) sort the following representations into elements, compounds, and mixtures. items (9 images) (drag and drop into the appropriate area below)

Explanation:

Step1: Recall definitions

An element has only one - type of atom, a compound has two or more different types of atoms chemically bonded, and a mixture has two or more substances (elements or compounds) physically mixed.

Step2: Analyze each representation

• Elements: Helium (C) has only helium atoms, mercury (D) has only mercury atoms, platinum (I) has only platinum atoms.
• Compounds: Glycine (B) has carbon, hydrogen, oxygen and nitrogen atoms chemically bonded, ammonia (F) has nitrogen and hydrogen atoms chemically bonded, hydrogen peroxide (G) has hydrogen and oxygen atoms chemically bonded, propane (H) has carbon and hydrogen atoms chemically bonded.
• Mixtures: Brass (A) is a mixture of copper and zinc, salt (E) is a mixture of different substances.

Answer:

Elements: C, D, I
