Yes
No, the proportion of iron and sulfur in a mixture is not always fixed. It depends on the specific composition of the mixture and how it was prepared. Different mixtures can have varying ratios of iron and sulfur based on their intended use or source.
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.
False. In a mixture, the constituents are not present in a fixed proportion; they can vary in amounts. This distinguishes mixtures from compounds, where elements are combined in specific ratios. Mixtures can be homogeneous or heterogeneous, depending on how well the components are mixed.
Carbon disulfide is a pure substance, not a mixture. It is a homogeneous compound composed of carbon and sulfur atoms in a fixed ratio.
A compound always has a fixed chemical composition where the elements are bonded together in specific ratios, forming a new substance with unique properties. In contrast, a mixture is a physical combination of two or more substances that can be separated by physical means, and the components retain their original properties.
No, the proportion of iron and sulfur in a mixture is not always fixed. It can vary depending on the composition of the mixture and how it was prepared. The proportion can be adjusted by changing the quantities of iron and sulfur added to the mixture.
No, the proportion of iron and sulfur in a mixture is not always fixed. It depends on the specific composition of the mixture and how it was prepared. Different mixtures can have varying ratios of iron and sulfur based on their intended use or source.
No mixture has no definite proportion
Sulfur trioxide is a compound, not a mixture. It is a chemical compound composed of sulfur and oxygen atoms in a fixed ratio.
It is a mixture.
It is a mixture.
A material that contains three elements joined in a fixed proportion is a pure substance called a compound. It is not a mixture.
Sulfur trioxide is a compound, because it always contains sulfur and oxygen in the same proportions to each other and features inter atomic chemical bonds.
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.
No, pure copper sulfate is not a mixture. It is a compound composed of copper, sulfur, and oxygen atoms in a fixed ratio.
Copper sulfate is a compound, not a mixture. It is composed of copper, sulfur, and oxygen elements chemically bonded in a fixed ratio.
Carbon disulfide is a pure substance, not a mixture. It is a homogeneous compound composed of carbon and sulfur atoms in a fixed ratio.
