Is the proportion of iron and sulfur in a mixture always fixed?
Yes
How can we determine that water is a compound not a mixture?
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.
One difference between a compound and a mixture is a compound always?
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.
What is a material that contains three elements joined in a 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.
What is a difference between a compound and a mixture that is a compound always?
A compound is a substance made up of two or more elements that are chemically bonded in a fixed proportion, whereas a mixture is a combination of two or more substances that are physically mixed together but not chemically bonded. This means that a compound always has a specific chemical formula and composition, while a mixture can vary in composition and can be separated by physical means.
Is the proportion of iron and sulfur in a mixture is always fixed?
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.
Is the proportion of iron and sulfur in a mixture always fixed?
Yes
Do mixture combine in set or fixed pattern?
No mixture has no definite proportion
If a material contains three elements but not joined in a fixed proportion it is a(an)?
It is a mixture.
If a material contains three elements but not joined in a fixed proportion it is a?
It is a mixture.
If a material contains three elements joined in a fixed proportion it is a(an)?
A material that contains three elements joined in a fixed proportion is a pure substance called a compound. It is not a mixture.
How can we determine that water is a compound not a mixture?
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.
Is SO2 a mixture?
No, SO2 is a pure substance. It is a chemical compound composed of sulfur and oxygen in a fixed ratio.
One difference between a compound and a mixture is a compound always?
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.

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.
What is a fixed proportion in chemistry?
A fixed proportion in chemistry refers to the specific ratio in which elements combine to form compounds. This means that the elements in a compound are always present in the same proportion by mass. For example, water is always composed of hydrogen and oxygen in a 2:1 ratio by mass.
What is the name of two or more elements in a fixed proportion?
A compound refers to two or more elements chemically bonded together in a fixed proportion. This fixed proportion is represented by a chemical formula that shows the types and ratios of atoms present in the compound.
