How do the properties of substances formed in chemical changes compare to those of the original substances?
Substances formed in chemical changes have different physical and chemical properties compared to the original substances. This can include changes in color, odor, state of matter, melting/boiling points, and reactivity. The chemical composition of the new substances is also different from the original substances.
What is changes of chemistry?
Changes in chemistry refer to alterations in the properties and composition of substances as a result of chemical reactions. These changes can be classified as physical changes, where the substance's form is altered without changing its composition, or chemical changes, where new substances are formed. Understanding these changes is fundamental to understanding the behavior of matter in various environments.
Does physical change differ from a chemical in that waste products are formed through chemical changes?
Yes, physical changes involve a change in the appearance or form of a substance without forming new substances. Chemical changes, on the other hand, involve the formation of new substances through the rearrangement of atoms. Waste products may be formed in chemical changes as new substances are produced.
What chemical changes provide evidence that a compound has formed?
Signs of chemical reactions may be: - Gas release - Formation of a precipitate - Change of color - Change of odor - Change of pH - Change of aspect - Visible formation of new compounds - A violent reaction with explosion or fire - Bubbling
Chemical reactions involve changes in what chemical that join atoms compounds?
Chemical reactions involve changes in the chemical bonds that join atoms to form compounds. During a chemical reaction, these bonds are broken and new bonds are formed, resulting in the rearrangement of atoms and the formation of new compounds.
What changes shape in a chemical reactions?
New molecules are formed.
Can you name two chemical changes?
Two examples of chemical changes are the rusting of iron and the combustion of gasoline. In chemical changes, new substances are formed due to the rearrangement of atoms.
When a physical changes occurs a substance's changes?
A new substance is formed only after a chemical change.
What are the similarities between chemical and physical changes?
Both chemical and physical changes involve a transformation of matter. In physical changes, the substance's chemical composition remains the same, while in chemical changes, new substances are formed as a result of a chemical reaction. Both types of changes involve the absorption or release of energy.
Is it true that A physical change differs from a chemical change in that waste products are formed through chemical changes?
yes
Can you explain the difference between physical changes and chemical changes?
Physical changes is change in property. Ex) change from solid to liquid....ice to water. Chemical change changes to different substances. Ex) rotting of fruit.

Is wood rotting a chemical change or physical change?
it is a chemical reaction because a new substance is formed when the wood rots
What is formed when a chemical change occurs?
When a chemical change occurs, new substances are formed with different chemical properties than the original substances. This process involves the breaking and forming of chemical bonds to create new molecules.
Is bituminous coal detrital or chemical in nature?
Bituminous coal is a chemical sedimentary rock, formed from the remains of plants that have undergone chemical changes over time.
Chemical changes in the structure shown are most likely to happen during?
Chemical changes in a structure are most likely to happen during a chemical reaction where bonds are broken and formed between atoms. This can occur when new substances are formed, leading to a change in the composition and properties of the structure.
