What term represents a compound?
Compounds can be described using element symbols and numbers
What is the chemical combination of two or more elements in definite proportions?
This is a chemical compound.
What are the 2 elements chemically linked in definite proportions called?
This is a chemical compound (a molecule).
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.
Are the elements that make up a compound joined in a fixed proportion?
This is an old rule (Law of definite proportions) not valid for nonstoichiometric compounds.
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.
What is the substance formed by the chemical combination of two or more elements in definite proportion?
A compound is the substance formed by the chemical combination of two or more elements in definite proportions. It has a unique chemical structure and properties different from its constituent elements.
What is a substance formed by the combination of two or more elements in definite proportions?
A chemical compound. The combination of two or more elements in definite proportions forms a compound. For instance, hydrogen and oxygen combine in a two to one ratio in order to form water. Similarly, one sodium atom reacts with one chlorine atom to form the ionic compound sodium chloride.

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.
What is the chemical combination of two or more elements in definite proportions?
This is a chemical compound.
What is the law that states that a chemical compound always contains the same elements in exactly the same proportions by w eight and mass?
The law you are referring to is the Law of Definite Proportions. This law states that a chemical compound always contains the same elements in the same proportions by mass, regardless of the source of the compound.
Why is water not a compound?
Water most definitely IS a compound! It is a compound composed of hydrogen and oxygen atoms chemically bonded in a definite proportion of 2H:1O. The molecular formula is H2O. A compound is a pure substance composed of different elements chemically bonded in definite proportions.
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.
When two or more elements bond together in definite proportions?
When forming a chemical compound.
When two or more elements bond together in definite proportions they form a?
Compound.
