No, it is your choice.

Water is a compound because its molecules are formed of chemically combined elements (hydrogen and oxygen) in a fixed proportion. A mixture is a combination of separate atoms, molecules, or particles that are not chemically bonded or in any fixed proportion.
If a material contains three elements joined in a fixed proportion, then it is a compound. It can only be separated by a chemical reaction.
This would be a mixture or a compound, you choose :D
A compound is similar to a homogeneous mixture in that the proportions of the atoms throughout the compound/mixture are always fixed and do not vary. For example, a sample of pure C02 gas is a compound and will always have two parts oxygen to every carbon atom. Likewise, a homogeneous mixture of salt water will always have a fixed proportion of salt ions to water. (However, a heterogeneous mixture, such as muddy water would not always have a fixed proportion of mud to water since the mud might settle towards the bottom. The solution strength of a heterogeneous mixture can vary while a homogeneous mixture remains constant).A homogeneous mixture can be separated into its constituent components by physical means. For example, you can evaporate off the water off a sugar-water mixture, or you can filter a mixture of water and sand.A compound, however, requires some kind of chemical reaction to separate it into its constituent elements.

No mixture has no definite proportion
It is a mixture.
It is a mixture.
a MIXTURE. If it was mixed in a fixed proportion you would get a compound!
A material that contains three elements joined in a fixed proportion is a pure substance called a compound. It is not a mixture.
