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?
A compound is the pure substance formed from the chemical combination of two or more different elements in a fixed ratio.

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 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?
A compound is a substance of two or more elements bounded together in definite atomical proportions
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?
A compound is the pure substance formed from the chemical combination of two or more different elements in a fixed ratio.
How are experimental data used to show that compound obeys the law of definite proportions?
The Law of Multiple Proportions states that two or more compounds may be made from the same elements but each compound will obey the Law of Definite Proportions. Combining two elements to create another element can only be done with precise measurements of each element or another element would be created instead of the one intended.
When two or more elements bond together in definite proportions?
When forming a chemical compound.
Is the amount of elements needed to make a compound always the same?
The proportions are always the same.
