Are the proportions of a mixture fixed or not fixed?
The proportions of a mixture can be fixed or not fixed, depending on the specific components and how they are combined. In a homogeneous mixture, such as a solution, the proportions of the components are fixed. In a heterogeneous mixture, such as a mixture of solids, the proportions can vary throughout the sample.
What is a fixed mixture?
A fixed mixture is a combination of substances that always maintains the same composition and properties throughout. The components of a fixed mixture are evenly distributed and cannot be separated by physical means like filtration or distillation. Examples include alloys like bronze and solutions like salt water.
What are the characterisitcs of a mixture?
A mixture is a combination of two or more substances that are not chemically bonded. Mixtures can be separated by physical means, such as filtration or distillation, and their properties can vary depending on the proportions of the components present. Mixtures do not have a fixed composition and the components retain their individual properties.
Does a heterogeneous mixture contain only fixed amounts of components?
No, a heterogeneous mixture does not contain fixed amounts of components. In a heterogeneous mixture, the substances are not evenly distributed, so the composition can vary from one part of the mixture to another. This makes it difficult to determine the exact amounts of each component.
A combination of substances in which no reaction takes place is?
A combination of substances in which no reaction takes place is called a mixture. In a mixture, the individual components maintain their distinct chemical properties and can be physically separated. Examples include salad, air, and sand mixed with salt. Unlike compounds, mixtures do not have a fixed composition or specific ratios of components.
A combination of two or more components that retain their identity?
A mixture is a combination of two or more components that maintain their individual identities within the mixture. Each component can be separated by physical means.
How is a mixture differnt from a compound?
A compound is a combination of two or more elements that are chemically bonded together in a fixed whole number ratio. A mixture is composed of two or more substances (elements or compounds) mixed together, but not chemically bonded to one another and are generally not in a fixed ratio. Unlike a compound, the components of a mixture can be separated by physical means.
Is metal alloys a mixture?
An alloy is a mixture of Metals. A mixture is a combination of elements in an unfixed ratio. A compound is a mixture of elements in a fixed ratio.
How is a homogenous mixture different from a compound?
In a compound the component elements are chemically bonded together in a fixed ratio. In a homogeneous mixture the components are not chemically bonded together and the ratio can vary.In a compound the component elements are chemically bonded together in a fixed ratio.In a homogeneous mixture the components are not chemically bonded together and the ratio can be varied.
Is chunky spaghetti sauce an element compound or mixture?
Chunky spaghetti sauce is absolutely a mixture because its components are not mixed in a fixed ratio by mass
What are the differences between a mixture and a compound?
A mixture can be separated by physical means, a compound cannotThe components of a compound are chemically bonded together, those in a mixture are not.In a compound the components are in a fixed, whole-number ratio, Those in a mixture are not.A compound is considered to be one substance, a mixture is two or more.
