Do antibiotics have any chemical substances?
The definition of a chemical substance is a material with a specific chemical composition. So yes, antibiotics contain chemical substances. Although, antibiotics will employ some sort of living microorganism, instead of just one simple chemical substance.
Which pair is classified as chemical substances?
compounds and elements because only compounds and elements have a specific set of physical and chemical properties.
What is the difference between atoms compounds minerals?
Minerals are solid homogeneous inorganic substances having a specific chemical composition that can be represented by a chemical formula. They are different from rocks, which can be a mixture of minerals and non-minerals and do not have a specific chemical composition.
Are compounds of the element?
The elements of a compound are the chemical bonds that are present in a specific ratio in a compound. Elements are pure chemical substances that are made of the same atom.
How the chemical combination of substances take place?
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.
Is there such thing as scientific names of substances?
Yes; today official scientific names of chemical substances are established by IUPAC (International Union of Pure and Applied Chemistry). Each country has a specific adaptation for this terminology. Also, exist numerical codes for chemical substances: CAS registry number (CAS is Chemical Abstract Service).
How would you describe chemicals?
A chemical substance is a material with a specific chemical composition. Generally, chemical substances exist as a solid, liquid, gas, or plasma and may change between these phases of matter with changes in temperature or pressure. Chemical reactions convert one chemical substance into another.
You want to make a jelly using chemical substances?
It's certainly easier than making a jelly using non-chemical substances. You're going to need to be a lot more specific if you want sensible answers.
Why do liquids show varied densities?
Because liquids are different substances or mixture of substances; each chemical compound (substance) has a specific density.
Why is it important to identify substances by their physical and chemical properties?
These properties are specific for each substance.
