What else can I help you with?
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.
Constituents of mixture are present in a fixed proportion true or false?
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.
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.
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.

Is SO2 a mixture?
No, SO2 is a pure substance. It is a chemical compound composed of sulfur and oxygen in a fixed ratio.

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.
