Question

Following is a list of properties of a sample of solid sulfur:

I. Brittle, crystalline solid.
II. Melting point of 113°C.
III. Density of 2.1 g/cm²
IV. Combines with oxygen to form sulfur dioxide.
Determine which characteristics are chemical properties. Explain.
a) IV. This property can only be determined by chemically reacting the sample of sulfur.
b) I and II. These properties can only be determined by chemically reacting the sample of sulfur.
c) III. These properties can only be determined by chemically reacting the sample of sulfur.
c) III. These properties can be determined by physical measurements. The sulfur does not need to react chemically to measure these properties.
d) III and IV. These properties can be determined by physical measurements. The sulfur does not need to react chemically to measure these properties.

Answer 1

Chemical properties describe the ability of a substance to react and form new substances. Property IV, combining with oxygen to form sulfur dioxide, is a chemical property.

Step-by-step explanation:

Chemical properties describe the characteristic ability of a substance to react to form new substances. Examples of chemical properties include flammability and the ability to combine with other substances to form new compounds.

Based on the given properties of solid sulfur, property IV - combining with oxygen to form sulfur dioxide - is a chemical property. This property can only be determined by chemically reacting the sample of sulfur.
