Yes: The characteristic named is part of the definition of a compound.
Matter with a definite composition is a pure substance, such as an element, molecule, molecular compound, or ionic compound.
No. A compound will always have the same 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.
always the same
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.
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.
called: Compound.
the composition varies from one compound to another
a compound always has the same chemical formula
The composition of air is practically the same at the level of earth.
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.
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.
