During the electrolysis of sodium sulfate, an electric current is passed through a solution of sodium sulfate, causing the compound to break down into its constituent elements, sodium, oxygen, and sulfur. This process involves the migration of ions towards the electrodes, where they undergo chemical reactions. As a result, the chemical composition of the substance changes, leading to the formation of sodium hydroxide, oxygen gas, and sulfuric acid.

How could you prove to someone that the dissolving was a physical to change not a chemical change?

You can demonstrate that dissolving is a physical change by showing that the chemical composition of the substance remains the same before and after dissolving. This can be done by evaporating the solvent and obtaining the original substance in its solid form. Chemical changes involve a change in the chemical composition of the substances involved, leading to the formation of new substances, which is not the case in dissolving.


Is reacting to air a physical or chemical property?

Reacting to air is a chemical property because it involves a change in the chemical composition of the substance when it comes into contact with oxygen in the air, leading to the formation of new compounds. It reflects how a substance interacts with its environment on a molecular level.


Is a change that produces a new substance is a chemical change?

False. This is a chemical change. A physical change is, for example, when Ice melts into water. It is the same element but it is in a different form. A chemical change is, for example, when two hydrogen atoms and an oxygen atom come together to form a water molecule, thereby producing a new substance.


Which of the following processes does not involve a chemical change in property A rusting B boiling C burning D fermenting?

Boiling does not involve a chemical change in property. Boiling is a physical change in which a substance changes from a liquid to a gas without changing its chemical composition. The other options (rusting, burning, fermenting) involve chemical reactions that result in changes to the chemical composition of the substances involved.


Is pH a physical or a chemical property?

pH stands for "potenz Hydrogen" (potenz is German for power).It represents how much hydrogen is present in a solution... so it is a chemical property

What is always involved when physical or chemical changes occur in matter?

When physical changes occur in matter, the substance's state or appearance changes without altering its chemical composition. In contrast, chemical changes involve a modification in the substance's chemical composition, resulting in the formation of new substances.


What are the 4 processes involved in physical change?

The four processes involved in physical change are melting, freezing, condensation, and evaporation. In each process, the substance changes state without altering its chemical composition.

Glucose is the "fuel" for muscles.


What is the process leading to a chemical change in matter?

A chemical change in matter occurs when the atoms in a substance rearrange to form new chemical bonds, leading to the creation of a new substance with different properties. This process typically involves the breaking of existing bonds and the formation of new bonds, resulting in a change in the composition and structure of the original substance. Energy is usually involved in the form of heat, light, or electricity to drive the chemical reaction.


Is reacts with oxygen to produce rust chemical property or physical property?

The reaction of iron with oxygen to produce rust is a chemical property because it involves a change in the composition and structure of the substances involved. Chemical properties describe how a substance reacts with other substances to form new materials.


A chemical substance involved with clotting?

One example of a chemical substance involved in clotting is thrombin. Thrombin is a key enzyme in the coagulation cascade that plays a critical role in converting fibrinogen to fibrin, which forms a blood clot. Dysregulation of thrombin activity can lead to bleeding disorders or thrombotic events.

What is involved in every chemical change?

One substance changing into a completley different substance. It cannot be reversed.


Is the ability to combine with another substance physical?

Yes, the ability to combine with another substance is a physical property that depends on the chemical composition and structure of the substances involved. The physical properties of the substances, such as molecular size, polarity, and intermolecular forces, determine how easily they can combine with each other.
