Identify the physical properties of aluminum from the paragraph below.

Aluminum is the most common metal in the Earth's crust. It is silvery white in color. It is highly chemically reactive and insoluble in water. The melting point of aluminum is 660.32ºC. Because aluminum is malleable and ductile, it can be used to manufacture a wide range of products. Aluminum is a good conductor of heat. Aluminum is difficult and expensive to refine from ores such as bauxite.
A. silvery white
B. chemically reactive
C. melting point = 660.32°C
D. malleable
E. expensive

Respuesta :

The physical properties of aluminum from the paragraph are silvery-white, melting point, malleable.
