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

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
