Answer from: swagmonstah24

The sentences among the group of answer choices that applies to physical and chemical properties are:

A. Chemical properties can only be observed during a chemical reaction.

B. The rusting of iron is a chemical property.

C. Melting and boiling points are physical properties.

E. The various components of a mixture do not combine chemically.

A physical property can be defined as the properties of a chemical compound (substance) that is measurable and observable without altering the chemical composition of the chemical compound (substance). Some examples of the physical properties of a substance are;

Density.Conductivity.Melting and boiling point.Color.

A chemical property can be defined as the properties of a chemical compound (substance) that is observable and measurable during a chemical reaction. Some examples of the chemical properties of a substance are;

Tarnishing. Flammability. Reactivity.Acidity.

In conclusion, we can deduce the following from the above definitions of physical and chemical properties;

I. A chemical property can only be observed and measured during a chemical reaction.

II. An example of a chemical property is the rusting of iron.

III. Melting and boiling points are considered to be physical properties.

IV. The various components of a mixture do not combine chemically.

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)
