Are the proportions of a mixture fixed?
No.
Are the proportions of a mixture fixed or not fixed?
I have been googling this sane question for the past 2 hours and there is no solution. Screw You!
Is mixture a substance?
No, a mixture is not a substance. They are two different items. A mixture is when two or more substances are mixed together using any proportions but can be separated physically. A substance is when two or more compounds or elements are combined chemically into fixed proportions but can only be separated chemically.
How are compounds and homogeneous mixtures similar?
A compound is similar to a homogeneous mixture in that the proportions of the atoms throughout the compound/mixture are always fixed and do not vary. For example, a sample of pure C02 gas is a compound and will always have two parts oxygen to every carbon atom. Likewise, a homogeneous mixture of salt water will always have a fixed proportion of salt ions to water. (However, a heterogeneous mixture, such as muddy water would not always have a fixed proportion of mud to water since the mud might settle towards the bottom. The solution strength of a heterogeneous mixture can vary while a homogeneous mixture remains constant).A homogeneous mixture can be separated into its constituent components by physical means. For example, you can evaporate off the water off a sugar-water mixture, or you can filter a mixture of water and sand.A compound, however, requires some kind of chemical reaction to separate it into its constituent elements.
What does daltons fourth postulate state?
Answer: in fixed proportions
Are the proportions of a mixture fixed?
No.
Is a mixture of elements a compound?
No, unless all the elements involved in the mixture are present in fixed atomic proportions to one another that are ratios of integers, thereby showing that the elements are chemically bonded.
When a substance which contains various elements or compounds without bonding or in fixed proportions is?
mixture

Does compound have a fixed composition?
I think so or maybe not. But if you add one more element then it will be mixture.
Are the proportions of a compound fixed or not fixed?
Fixed.
What consitutes a mixture?
A mixture is when two substances combine together. However in a mixture there is no chemical bonding in fixed proportions. It is like rocky road ice cream. Chocolate and ice cream mixed together forms a mixture.
What is the rule of constant proportions?
The law of constant proportions, also called Proust's law, states that the elements in a compound are all present in a fixed proportion by weight, regardless of how the compound is prepared.
What make's a mixture a mixture?
A mixture is a combination of two or more substances that are not chemically united and do not exist in fixed proportions to each other.
Is mixture a substance?
No, a mixture is not a substance. They are two different items. A mixture is when two or more substances are mixed together using any proportions but can be separated physically.

What are composed of atoms in fixed proportions?
elements
Composed of atoms in fixed proportions?
