What are two or more substances that are chemically combined in a fixed proportion called?
Compound
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.
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 the proportion of iron and sulphur in a mixture always fixed?
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.
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.
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.
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.
Are the sample mean and sample proportion of a population are called population parameters?
No, the sample mean and sample proportion are not called population parameters; they are referred to as sample statistics. Population parameters are fixed values that describe a characteristic of the entire population, such as the population mean or population proportion. Sample statistics are estimates derived from a sample and are used to infer about the corresponding population parameters.
What is high gearing?

Is the proportion of iron and sulfur in a mixture always fixed?
Yes
Total variable cost does not increase in proportion to output is it true?
False, it is the fixed cost which is not increased or decreased with proportion to output.
What does having a fixed composition mean?
Having a fixed composition means that a substance always contains the same elements in the same proportion by mass. This characteristic is a defining feature of pure substances like elements and compounds.
What does proportion period mean?

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)?
