A chemical combination of two or more substance in variable proportions is called?
A chemical combination of two or more substances in variable proportions is called a mixture. Mixtures can be either homogeneous (uniform composition throughout) or heterogeneous (non-uniform composition).
What is made of two or more of something in exact proportions?
Physically, a mixture. Chemically, a compound.
How does changing the amount of one substance affect a mixture identity and compounds identity?
The compounds identity remain unchanged; but the new mixture is different.
Is pure water a homogeneous mixture or heterogeneous?
Pure water is a homogeneous mixture because it has a uniform composition throughout, with the same proportions of water molecules.
Is gun pouder a mixture?
Yes, gunpowder is a mixture of potassium nitrate, charcoal, and sulfur. These three components are combined in specific proportions to create the explosive powder used in firearms.
Are the proportions of a mixture fixed or not fixed?
The proportions of a mixture can be fixed or not fixed, depending on the specific components and how they are combined. In a homogeneous mixture, such as a solution, the proportions of the components are fixed. In a heterogeneous mixture, such as a mixture of solids, the proportions can vary throughout the sample.
Are the proportions of a mixture fixed?
No.
Is gun powder a pure substance?
Gunpowder is not a pure substance. It is a mixture composed of potassium nitrate, charcoal, and sulfur in specific proportions. Each of these individual components maintains its chemical identity in the mixture.
Is substances maintain their identity in a heterogeneous mixture but not in a homogeneous mixture?
The identity remain the same.
How does avartar relate to identity?
It doesn't!
How does changing the amount of one substance affect a mixture's identity and compound's identity?
The compounds identity remain unchanged; but the new mixture is different.
How does changing the amount of one substance affect mixture's identity and a compound's identity?
The compounds identity remain unchanged; but the new mixture is different.
Two evenly mixed substances is called?
a homogeneous mixture they have the same proportions through out a given example
What are the differences between hetrogeneous and homogeneous mixtures?
A homogeneous mixture contains the same proportions of its ingredients throughout the mixture. A heterogeneous mixture does not.
A chemical combination of two or more substance in variable proportions is called?
A chemical combination of two or more substances in variable proportions is called a mixture. Mixtures can be either homogeneous (uniform composition throughout) or heterogeneous (non-uniform composition).
What Is The Specific Gravity Of mixture of Gas And Water?
The specific gravity of a mixture of gas and water would depend on the proportions of gas and water in the mixture. Gas would typically have a much lower specific gravity than water. The specific gravity of the mixture can be calculated by taking into account the specific gravity of each component and their respective proportions in the mixture.
Why can you write a formula for compounds but not for a mixture?
Because in a mixture, there are no bonds formed between the elements, and therefore the proportions of each element are unknown, for the mixture as a whole. A mixture is not a chemical change.
