It's a compound. H2O2 is hydrogen peroxide. It as two different elements that is what a compound is.
Silicon is an element, not a compound or mixture. It is a non-metallic chemical element with the symbol Si and atomic number 14.
Starch is an organic compound.
Gasoline is a compound. It is a hydrocarbon.
Salt water is a mixture of water and salt, oxygen is a compound, and air is a mixture of gases like nitrogen, oxygen, and carbon dioxide. Oxygen is an element found in the air, but salt water does not contain oxygen as an element.
A compound: any formula that contains more than one kind of atomic symbols represents a compound.
Silicon is an element, not a compound or mixture. It is a non-metallic chemical element with the symbol Si and atomic number 14.
It is a compound and of heterogeneous mixture. Considering that it has many ingredients that do not uniformly cohere into one single substance.
Starch is an organic compound.
Gasoline is a compound. It is a hydrocarbon.
No. It is a heterogeneous mixture.
Salt water is a mixture of water and salt, oxygen is a compound, and air is a mixture of gases like nitrogen, oxygen, and carbon dioxide. Oxygen is an element found in the air, but salt water does not contain oxygen as an element.
A compound: any formula that contains more than one kind of atomic symbols represents a compound.
Nitrogen (N) is a chemical element.
Nitrogen naturally occurs as a diatomic molecule (N2). Nitrogen, by itself, is an element.
It is a compond. It is made up of N and H
NO!!! It is NOT an element. By the very fact that the formula is NH3 , tells, us that a molecule of ammonia contains nitrogen(N) and hydrogen(H) in COMBINATION; a COMPOUND.
No. Coffee is not a chemical element. Neither is the cup. They are both heterogenous mixtures of different compounds.
