Question

1. fill in the flowchart below using the following terms: matter, substance, heterogenous, compound, element, homogenous, mixture. matter fixed proportion physically combined on the periodic table chemically combined different same

Explanation:

Step1: Categorize matter

Matter can be divided into substances and mixtures. Substances have a fixed - proportion composition, while mixtures are physically combined. So the first box on the left is "Substance" and the first box on the right is "Mixture".

Step2: Further categorize substances

Substances can be elements (found on the periodic table) or compounds (chemically combined). So the second - level left box under "Substance" is "Element" and the second - level right box under "Substance" is "Compound".

Step3: Categorize mixtures

Mixtures can be heterogeneous (components are different) or homogeneous (components are the same). So the second - level left box under "Mixture" is "Heterogeneous" and the second - level right box under "Mixture" is "Homogeneous".

Answer:

Left branch (top - down): Substance, Element, Compound
Right branch (top - down): Mixture, Heterogeneous, Homogeneous
