Can ammonia be broken down by chemical means?
Potassium can’t be broken down by chemical change because it’s an element, which is the simplest form of matter. Sulfuric acid, ammonia and water are all compounds composed of elements. Compounds can be broken down into simpler compounds or elements by a chemical reaction.
Can ammonia be broken down by chemical change?
(1) Ammonia is composed of one nitrogen and three hydrogen atoms so it is a compound. Therefore it can be broken down by chemical change.
Which is a physical property of aluminum *?
Physical properties It has a melting point of 660°C (1,220°F) and a boiling point of 2,327-2,450°C (4,221-4,442°F). The density is 2.708 grams per cubic centimeter. Aluminum is both ductile and malleable. Ductile means capable of being pulled into thin wires.
What are three physical properties of aluminum foil?

What are three physical properties of carbon?
Carbon dioxide is the by product of combustion and metabolism. Physical Properties: Carbon is a soft, dull gray or black non-metal that you can scratch with a fingernail. Th density of carbon as graphite is 2.267 g/mL, which means it will sink in water.
What is the unique properties of carbon?
(a) The most unique property of carbon atom is its ability to combine itself, atom to atom to form long chains. This property of self combination is useful to us because it gives rise to an extremely large number of carbon compounds (or organic compounds). (b) A diamond crystal is a giant molecule of carbon atoms.
What are two carbon properties?
The two features of carbon that give rise to a large number of compounds are as follows: (i) Catenation: It is the ability to form bonds with other atoms of carbon. (ii) Tetravalency: With the valency of four, carbon is capable of bonding with four other atoms.
