What else can I help you with?
What is a matter with a composition that is always the same?
Matter with a definite composition is a pure substance, such as an element, molecule, molecular compound, or ionic compound.
Do compounds have varying compositions?
No. A compound will always have the same composition.
Do all pure samples of a given compound have the same percent composition?
A compound is a combination of two or more elements. These elements join together based on their molecular bonds. No two elements combine in the same percentage.
Is the law of definite proportions says that the composition of a compound always the same?
always the same
What happens when you change the composition of a mixture and a compound?
When you change the composition of a mixture, you are altering the relative amounts of the substances mixed together, while their chemical properties remain the same. In contrast, changing the composition of a compound involves altering the elements that make up the compound, leading to the formation of a new substance with different chemical properties.
Does the composition of the same compound differ from on location to another?
No, the composition of the same compound does not differ from one location to another. A compound has a fixed chemical formula regardless of where it is found. The arrangement of atoms and elements within the compound remains consistent regardless of its location.
What is a substance that has a fixed composition and differs from a mixture because every sample has the exact same characteristics and every sample has the exact same composition?
called: Compound.
Composition of inorganic compound?
the composition varies from one compound to another
What always stays the same in a compound?
a compound always has the same chemical formula
Why Is air a homogeneous mixture and not a compound?
The composition of air is practically the same at the level of earth.
Explain how your class's results in this experiment support the law of definite composition?
The law of definite composition states that a compound will always have the same proportion of elements by mass regardless of the source or how it was prepared. In the experiment, if the class obtained consistent results in terms of the mass of elements present in the compound, it would support this law. This consistency would demonstrate that the compound was formed with a fixed ratio of elements, reinforcing the idea that compounds have a definite composition.
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.
