When elements combine to make a compound is it always in the same proportion?

No, the elements are not always in the same proportion.
For example, two atoms of hydrogen combine with one atom of oxygen to make a single molecule of water. But one atom of hydrogen combines with one atom of fluorine to make a single molecule of hydrogen fluoride.
The numbers of atoms involved depends on the number of electrons available in the outer electron clouds of the atoms involved.

What is the law of definite 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
Do elements always combine in specific ratios?
The Law of Definite Proportions says that a given chemical compound always contains the same proportion by mass of its constituent elements. This is NOT the same as saying that elements always combine in a specific ratio, because they can combine in different ratios in different compounds. An example of this might be copper oxide which can be CuO or Cu2O, showing a different ratio of copper to oxygen. So, the answer to the question, as asked, is no, elements do not always combine in specific ratios.
What is a fixed proportion in chemistry?
You think probable to the law of definite proportions: the ratio of elements in a compound is always the same. Now this law is for the most part obsolete.
Is hydrochloric acid an element a compound or a mixture?
Is Hydrochloric acid HCL is a compound. Hydrochloric acid is a solution of hydrogen chloride in water.
Does a compound contain elements combined in a specific ratio?
You think probable to a chemical compound.
A given compound is always made of the same elements in the same?
A given compound is always made of the same elements in the same proportion.
A compound differs from a mixture because it?
always contains the same elements in the same proportion.

What is meant by law of constant proportion and how is this law applied in experiment empirical formula of a compound?
The law of constant proportion states that a pure chemical compound always contains exactly the same proportion of elements by mass.This information, together with the atomic masses of the elements in the compound enable scientists to determine the formula of a compound.

Who proposed the theory that the elements in a compound always combine in the same fixed ratio?
Dalton
One difference between a compound and a mixture is a compound always?
A compound is composed of two or more elements chemically combined in a definite proportion. The components of a mixture are not chemically combined and can vary in proportion.
What theory states that a given compound will always contain exactly the same proportion of elements by weight?
Law of definite proportion or law of definite composition.
Who proposed the theory that elements in a compound always combine in the same fixed ratio?
John Dalton.
