When elements are combined to form compounds do their properties change?
Almost all elements can be combined into compounds, for example water=h20 steel=iron and carbon. Their properties usually change. For example when carbon is added to iron to make steel, it becomes stronger and more durable. Humans use compounds to our advantage, adding various elements to materials to make them water proof, stronger, more flexible, harder e.g
Can chemicals change by being combined with other chemicals?
Chemicals yes, elements however, no. Elements are themselves chemicals, Burn hydrogen in oxygen and you'll end up with water, another chemical.
When elements combine to form compounds their properties change?
The chemical properties of atoms are significantly changed when they form compounds. When elements combine to form compounds it is called a chemical reaction. The compound is then a collection of molecules and each molecule has are still the same atoms as one started with, but the arrangement of the electrons in the atoms has changed.
Is germanium a physical or chemical change?
Germanium is a chemical element, so its presence or absence is considered a physical change. However, if germanium is combined with other elements to form compounds, the resulting chemical reaction would be classified as a chemical change.
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
Do compounds containing iron and copper look like the elements iron and copper?
Compounds containing iron and copper do not typically resemble the pure elements in their metallic form. When combined in compounds, the properties and appearance of the elements change due to their chemical bonding with other elements.
When elements combine to form compounds is this a physical or chemical change?
This is a chemical change.
Who decided that atoms do not change when chemical combined into compounds?
Jesus Christ

Do the properties of elements change when combined to form compounds true or false?
no they dont chane
Can compounds may be broken down into elements in a chemical change?
yes they can
Are compounds broken down into elements by chemical or physical change?
its a chemical change. a physical change does not change the chemical makeup of a substance. it simply changes its form or physical state. examples: ice melting, a tree being chopped down.
A substance in which two or more elements are combined in fixed proportions?
a chemical change
In a chemical change what is always formed?
A chemical change always forms one or more products which can be elements, molecules, and/or compounds.
Is decompostion of water a physical change?
Yes, it is a chemical change; new compounds (elements) are formed !
