A composition of an element is only fixed if it doesn't radioactively decay, chemically react, interact with a fundamental particle, and no external energy is introduced into the system. These four things happen quite a bit though and if they don't the element stays the same because it is at the lowest energy state it can obtain.
What else can I help you with?
If the composition of a material is fixed?
If the composition of a material is fixed, it means that the material is made up of a set combination of elements in specific proportions. This fixed composition gives the material its unique properties and characteristics, which remain consistent as long as the composition is maintained.
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.
Which is not a characteristic of a compound?
One of the characteristics of a compound is that it has a fixed chemical composition.
Does compound have a fixed composition?
Yes, compounds have a fixed composition because they are made up of a specific ratio of different elements bonded together in a precise manner. This fixed composition gives compounds specific properties and characteristics that are different from the individual elements that make them up.
Is all composition of a compound fixed but that of a mixture is not true or false?
False. The composition of a compound is fixed, meaning it always contains the same elements in the same proportions. In contrast, the composition of a mixture can vary, as it is a physical combination of substances that can be in different proportions.
What is fixed composition?
Fixed composition refers to a mixture where the components are present in a specific and unchanging ratio. This means the proportion of each component in the mixture remains constant regardless of the amount of the mixture present. Fixed composition is often found in chemical compounds where the elements are combined in a defined ratio.
Why dont compounds differ from mixtures?
Compounds differ from mixtures because compounds have a fixed chemical composition with elements chemically bonded in a specific ratio, while mixtures can vary in composition with no fixed ratio. Compounds have specific properties different from their constituent elements, while mixtures retain the properties of their components.
What is the substance with a constant composition that can be broken down into elements?
A chemical compound is a substance with a constant composition that can be broken down into elements through chemical reactions. A compound is made up of two or more different elements chemically bonded together in fixed proportions.
Is fixed composition a caracteritic of a mixture?
A fixed composition is not a characteristic of a mixture. The composition of a mixture can vary, unlike the composition of a compound that forms a chemical reaction.
What has a fixed composition and is always homogeneous?
A compound has a fixed composition and is always a homogeneous pure substance.
How is the Law of definite composition and proportion relate to the empirical formula?
The Law of Definite Composition states that a compound will always have the same proportion of elements by mass. This relates to the empirical formula because the empirical formula gives the simplest whole number ratio of the elements in a compound, which reflects the fixed composition of elements as per the Law of Definite Composition.
Do compounds have a definite composition?
Yes, compounds have a definite chemical composition. This means they are made up of a specific ratio of elements that are bonded together in a fixed arrangement. This composition can be represented by a chemical formula.
