What expresses the relationship between elements in the compounds and the molecules they make up?
Chemical Formula :)
Is formation of a gas is a chemical change?
The formation of gas is:- a chemical process if the gas is the product of a chemical reaction- a physical process if the gas is the product of a change of phase as sublimation and vaporization
What do you call combinations of two or more elements Sodium chloride and magnesium sulfate are examples?
Chemical compounds are molecules made up of two or more elements.
What is a substance which contains atoms of two or more elements combined together?
Hydrogen and Oxygen are only two elements in water
What is the relationship among atoms elements and molecules?
atoms combine to form molecules of elements
What is a nature of a molecules?
Molecules are formed from chemical elements associated by chemical bonds.
What is the difference between elements and nutrients?
Nutrients are chemical compounds; they contain molecules - and the molecules are formed from chemical elements.
What are the molecules?
Molecules are chemical entities formed from two or more elements associated by chemical bonds.
How are reactant elements or molecules different than the compound produced in a chemical reaction?
reactant elements and molecules are used in a chemical reaction, they are not mixed or combined or produced in a chemical reaction.
What are made up of different elements?
Molecules are formed from chemical elements.
Can new elements be produced in a chemical reaction can new molecules be produced through a chemical reaction?
New elements can by obtained only by nuclear reactions.New molecules can be obtained by chemical reactions.
What role of properties of elements and simple molecules play in chemical evolution?
The most important is the electronegativity of chemical elements.
How are molecules built and broke down?
Molecules are formed by synthesis from elements; molecules are broken by chemical reactions.
Most elements are combined with one or more other elements in?
Elements form molecules of chemical compounds
When can molecules form a compound?
One defining characteristic of a chemical compound is the inclusion of two or more chemical elements. When atoms of those different elements bond in a fixed ratio, the resulting molecules constitute a chemical compound. Molecules of a single chemical element (such as O2) are not considered compounds.
What reactants are in chemical reaction?
The elements or molecules that participate in a chemical reaction and yield a product.
Chemical bonding is the combining of elements to form what?
to form molecules
