Which equation represents a physical change?
Burning coal is a chemical reaction, a chemical change; but the solid reactant is transformed in gaseous products (H2O and CO2) - this is a physical change.
Is using a dehumidifier for moisture a chemical or physical change?
No. It is a physical change.
Is water turning to snow a chemical or physical change?
Changes of state are physical changes.
Is smoke a physical change?
It's not a physical change. Rather, it is a sign of an already completed chemical reaction.
When a physical change occurs in a sample of matter which is the matter that does not change?
During a physical change, the chemical composition of the matter remains the same, while its physical properties, such as shape, size, or state, may change. The individual particles that make up the matter do not change in a physical change.
What is physical products?
involves a change in the organinal subtance.
Name two products that are made through physical change?
Examples:- copper wire- wheat flour
When do the physical and chemical properties change?
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.
Why is shapening a pencil a physical change?
no new chemical products are formed .there is only a change in shape .the products after and before are same that is wood and graphite
How dowhen a physical change occurs opposed to a chemical change?
A physical change does not change the chemical composition of the substance undergoing the change, while a chemical change involves a change in chemical composition of the reactants in order to form the products.
Is it true that A physical change differs from a chemical change in that waste products are formed through chemical changes?
yes
What is chemical reaction physical reaction?
A physical change is one in which the chemical composition of the substance does not change. A chemical change is one in which new products are formed with their own unique chemical compositions and properties.
What are the products formed after a mixture is formed?
The product formed depends with the type of change that occurs whether it is a chemical or a physical change.
How you tell if matter has undergone a chemical change or a physical change?
If a chemical change has occurred, the chemical composition has changed and new products will have formed, different from the reactants. If a physical change has occurred, the chemical composition does not change and no new products will have formed.
Is filtering coffee a physical or chemical change?
filtering coffee is a physical change as no new products are formed after filtering and is reversible..
Is the reaction between carbon dioxide and limewater physical?
Since it gives differed products, its a chemical change.
Is a physical reaction is a process that one or more reactants change into one or more products with different properties?
No, a physical reaction does not involve the change of reactants into products with different properties. Instead, it refers to a process where the physical state or appearance of a substance changes, such as melting, freezing, or dissolving, without altering its chemical composition. In contrast, a chemical reaction involves the transformation of reactants into products that have different properties.
