A compound is a substance composed of two or more elements chemically bonded in fixed proportions. The elements in a compound are present in set ratios determined by the compound's chemical formula. Each compound has a unique combination of elements and proportions that define its chemical properties.

What term describes a substance formed by the combination of two ore more elements in definite proportions?
A compound is a substance formed by the combination of two or more elements in definite proportions. Each compound has a specific chemical formula that indicates the types of atoms present and the ratio in which they are combined.
Are the proportions of a compound fixed or not fixed?
The proportions of elements in a compound are fixed, meaning that a specific compound will always have the same ratio of elements by mass. This fixed ratio is determined by the chemical formula of the compound.
Who said that a given compound always contains the same elements in the same proportions by mass?
This statement was made by French chemist Joseph Proust and is known as the Law of Definite Proportions. It states that a compound always contains the same elements in the same proportions by mass regardless of the source of the compound.
State the law of definite proportions?
The law of definite proportions states that a compound always contains the same elements in the same proportion by mass, regardless of the source of the compound. This means that for a given compound, the ratio of the masses of the elements is always constant.
When two or more different elements joined together in fixed proportions is known as?
When two or more different elements are joined together in fixed proportions, it is known as a compound. Compounds have unique properties that differ from the elements they are made of.

Are elements that make up a compound always present in the same proportions?
No, elements in a compound are not always present in the same proportions. The ratio of elements in a compound is determined by its chemical formula.
Are the proportions of a compound fixed or not fixed?
The proportions of elements in a compound are fixed, meaning that a specific compound will always have the same ratio of elements by mass. This fixed ratio is determined by the chemical formula of the compound.
Is a compound a substance of two or more elements bounded together in definite proportions?
Yes, a compound is a substance composed of two or more elements chemically bonded together in specific proportions. These elements combine to form a new substance with unique properties.
What is the law of proportions?
A chemical compound always contains exactly the same proportion of elements by mass. ---------------------------------------------------------------------------------------------------- A law that states that a compound always contains the same elements in the same proportions. Source: e2020

What is the chemical combination of two or more elements in definite proportions?
This is a chemical compound.
When two or more different elements joined together in fixed proportions is known as?
When two or more different elements are joined together in fixed proportions, it is known as a compound. Compounds have unique properties that differ from the elements they are made of.
How are experimental data used to show that compound obeys the law of definite proportions?
Experimental data can be used to show that a compound obeys the law of definite proportions by determining the mass ratios of elements in the compound. By analyzing the masses of elements present in different samples of the compound and comparing them, one can show that the elements combine in specific, fixed ratios according to the law of definite proportions.
