Question

1. complete the chart below with every physical and chemical property listed in the text.

physical properties (can you find all 12?)	chemical properties (can you find all 5?)

1. viscosity is property of matter. viscosity describes a fluids resistance to flow. syrup and honey do not flow very fast when compared to water, so they are more viscous. is viscosity a physical or a chemical property? explain your answer.
2. a spoon made of pure silver has a mass of 15 grams, a volume of 1.43cm³, and a density of 10.49g/cm³. silver is used in spoons because it has no toxicity to humans. silver is a shiny metal which tarnishes (reacts with gases in the air) easily. it has a melting point of 960°c and a boiling point of 2212°c. it is used in jewelry because it is malleable, and its used in electrical circuits because it has a high electrical conductivity. silver is not magnetic.

a. what are the physical properties of a silver spoon?
b. what are the chemical properties of a silver spoon?

Explanation:

Step1: Identify physical properties

Physical properties can be observed or measured without changing the substance's chemical identity. For silver spoon, mass (15 grams), volume (1.43 cm³), density (10.49 g/cm³), shininess, melting - point (960°C), boiling - point (2212°C), malleability, non - magnetism, high electrical conductivity are physical properties.

Step2: Identify chemical properties

Chemical properties describe how a substance reacts with other substances. For silver spoon, tarnishing (reacting with gases in the air) and non - toxicity to humans are chemical properties.

Step3: Determine viscosity property

Viscosity is a physical property as it can be observed (comparing flow rates of different fluids) without changing the chemical composition of the fluid.

Answer:

2.

Physical Properties	Chemical Properties

1. Viscosity is a physical property. It can be observed by comparing the flow rates of different fluids without changing their chemical composition.

4.
a. Mass, volume, density, shininess, melting point, boiling point, malleability, non - magnetism, high electrical conductivity
b. Tarnishing, non - toxicity to humans
