A chemical substance is a material with a specific chemical compound.
A common example of a chemical substance is pure water; it has the same properties and the same ratioof hydrogen to oxygen whether it is isolated from a river or made in a laboratory. Some typical chemical substances are diamond, gold, salt (sodium chloride) and sugar (sucrose). Generally, chemical substances exist as a solid, liquid, or gas, and may change between these phases of matter with changes intemperature or pressure. Chemical reactions convert one chemical substance into another.
Forms of energy, such as light and heat, are not considered to be matter, and thus they are not "substances" in this regard.
What else can I help you with?
Do elements that combine in changing ratios form mixtures?
When elements combine in changing ratios, they form compounds rather than mixtures. Mixtures are made up of different substances that are not chemically bonded together, while compounds are formed by chemical bonding between elements in specific ratios.
Why these pure substances come up into mixtures?
Pure substances come up into mixtures because different substances can combine physically without undergoing a chemical reaction. These mixtures can be either homogeneous (uniform composition) or heterogeneous (non-uniform composition) depending on the interactions between the pure substances. Mixing pure substances allows for the creation of new materials with unique properties and characteristics.
What are the different substances to which acetanilide form eutectic mixtures?
Acetanilide can form eutectic mixtures with substances like urea, phenacetin, and resorcinol. Eutectic mixtures can have lower melting points than either pure component, making them useful in various applications such as pharmaceuticals and organic synthesis.
Is everything on earth made of different types of atoms?
Yes, everything on Earth is made up of atoms. Atoms are the basic building blocks of matter and combine in different ways to form various substances, such as elements, compounds, and mixtures.
Substances are divided into two classes?
Some people divide matter into pure substances and mixtures. Pure substances are elements and compounds. Mixtures include homogeneous and heterogeneous mixtures. Some people divide matter into homogeneous matter and heterogeneous matter. Homogeneous matter includes pure substances and homogeneous mixtures (solutions). Heterogeneous matter is heterogeneous mixtures.
Mixtures are?
Mixtures are materials made up of two different substances which do not combine chemically.
Do elements that combine in changing ratios form mixtures?
When elements combine in changing ratios, they form compounds rather than mixtures. Mixtures are made up of different substances that are not chemically bonded together, while compounds are formed by chemical bonding between elements in specific ratios.
Do heterogeneous mixtures combine to form compounds?
No. Heterogeneous mixtures are not compounds.
Do heterogeneous mixtures combine chemically?
No, heterogeneous mixtures do not combine chemically. In a heterogeneous mixture, the substances are physically mixed together but retain their individual properties. There is no chemical bonding between the components of a heterogeneous mixture.
What is substances combined in random amounts?
Substances combined in random amounts are called mixtures. Mixtures are made up of two or more different substances that are physically mixed together but do not chemically combine. Examples of mixtures include saltwater, air, and trail mix.
What is formed when two substances combine and form a new substances combine and form a new substance which cannot return to their original form?
a chemical reaction
When two substances combine to form a mixture the properties of substances what is it?
i have no idea :)
What are two or substances placed together but do not combine?
These substances form a mixture.
Why do chemicals combine?
To form new substances.
Helium can combine with what to form new substances?
helium does not combine with any element
When substances combine to form a compound what happens to the original properties of the substances?
When substances combine and retain their own properties, the result is a mixture.
What are two or more substances placed together but do not combine?
These substances form a mixture.
