What is substances in which two or more elements are combined in s fixed proportion?
Easy- any compound.
Water- H20- Two hydrogen atoms for every oxygen atom
Carbon Dioxide- CO2- Two oxygen atoms for every carbon
Table Salt- NaCl- One sodium atom for every chlorine
Sulfuric acid- H2SO4- A molecule of this contains two hydrogen, one sulfur, and four oxygen atoms

What are two or more substances that are chemically combined in a fixed proportion called?
Compound
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.
Whats the difference between a compound and a mixture?
a compound is a substance that contains two or more elements chemically combined in a fixed proportion while mixture is a physical blend of two or more substances that are not chemically combined
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 are compounds and mixture?
Elements: Pure substance. Made up of only itself (Ex: Oxygen).Compound: A substance made up of two or more elements that are chemically combined (Ex. Water- dihydrogenmonoxide= H2O).Mixture: Combination of substances (substances can be elements, compounds, or both). These substances are NOTchemically combined, which means that mixtures are differentfrom compounds.
The composition of a mixture can vary unlike a compound?
Yes, in a mixture, the substances are physically combined and can be present in any proportion. This allows the composition to vary, unlike a compound where the elements are chemically combined in fixed ratios.
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.
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.
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.
What substance that contains 2 or more elements chemically combined in a fixed proportion?
A substance made of two or more elements chemically combined in a specific proportion is called a compound. A substance composed of two or more elements combined chemically in a fixed proportion by mass is called a compound. A chemical compound can be held together by a covalent bond or an ionic bond.
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.
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.
Whats the difference between a compound and a mixture?
a compound is a substance that contains two or more elements chemically combined in a fixed proportion while mixture is a physical blend of two or more substances that are not chemically combined
One difference between a compound and a mixture is a compound always?
