When elements or molecules combine to form a new compound what reaction it occurs?
When elements or molecules combine to form a new compound, a chemical reaction occurs. This process involves the rearrangement of atoms to create new bonds and result in a different composition than the original substances.
What happens to the original substance during a chemical reaction?
The original substances are transformed during a chemical reaction a new substance (compound) is obtained.
One difference between a compound and a mixture is a compound always?
A compound always has a fixed chemical composition where the elements are bonded together in specific ratios, forming a new substance with unique properties. In contrast, a mixture is a physical combination of two or more substances that can be separated by physical means, and the components retain their original properties.
What is it called when an original material is transformed into a new material?
That process is called transformation or transmutation where the original material undergoes a change in its chemical or physical composition resulting in a new material.
What type of bond is penicillin?
Penicilline is not a 'bond' but a compound. The chemical formula is: C16H18N2O4S (the original PenG, benzylpenicilline)
Why is heating copper sulfate a chemical change?
Heating copper sulfate causes a chemical change because it leads to the compound decomposing into different substances, namely copper oxide and sulfur dioxide. This change alters the chemical composition and properties of the original compound, indicating a chemical reaction has occurred.
Physical changes do not changes the original what of matter?
Chemical composition

What the change that produce matter with a different composition than the original matter?
This is a chemical change.
What is a substance that retains its original chemical composition while bringing about a change in a substrate?
catalyst
Is the original water liquid sample a compound an element a heterogeneous mixture or a homogeneous mixture?
Water (H2O) is a chemical compound.
Is it a chemical change when a compound splits into its original elements?
Yes, that would be a decomposition reaction.
In a physical change some of the physical properties of the substance may be altered and the chemical composition?
In a physical change, the chemical composition of the substance remains the same, but some physical properties like shape, size, or state may change. This means that the substance can be reversed back to its original state without undergoing a chemical reaction.
One difference between a compound and a mixture is a compound always?
A compound always has a fixed chemical composition where the elements are bonded together in specific ratios, forming a new substance with unique properties. In contrast, a mixture is a physical combination of two or more substances that can be separated by physical means, and the components retain their original properties.
Which substance can be broken down by a chemical change The answer is Hexane--but why?
Hexane is a compound. All chemical compounds can be broken down by chemical change (chemical reactions of many types) - not only hexane. All the other choices are elements which cannot be broken down by chemical changes.
When matter undergoes a chemical change does the composition of the matter change?
Yes, when matter undergoes a chemical change, the composition of the matter changes at the molecular level. New substances are formed with different chemical properties than the original substances.
