When an electric current is passed through water during thr process of electrolysis, two gases are formed. One gas has boiling point of -183C and the other has a boiling point of -183C and the other has a boiling point of -253C, Jas a physical change or a chemical change occurred? Explain.
THATS IT IM GOING TO BRAINLY
Use brainly
I Think its Physical Change Because when objects or substances undergo a change a substance changes or one or more substances combine or break up to form new substances
chemical
the water's chemical bond has been broken, yielding its constituent elements
... the lower boiling point gas is hydrogen, the higher is oxygen
To determine whether a physical or chemical change occurred during the electrolysis of water, we need to understand the definition of these terms:
1. Physical change: A physical change involves altering the state or appearance of a substance without changing its chemical composition. Examples include changes in shape, size, phase (solid, liquid, gas), or physical properties such as melting or boiling point.
2. Chemical change: A chemical change, also known as a chemical reaction, occurs when the substances involved undergo a transformation at the molecular level, resulting in the creation of new substances with different chemical properties.
Now, let's analyze the given information. During the process of electrolysis, when an electric current is passed through water, two gases are formed. One gas has a boiling point of -183°C (degrees Celsius), while the other gas has a boiling point of -253°C.
Based on this information, we can conclude that a chemical change has occurred. Here's why:
1. The formation of gases: The production of two gases indicates that a chemical reaction has taken place. Gases are typically the result of chemical reactions, as they are composed of molecules with different chemical properties than the original substances.
2. Different boiling points: The fact that the two gases have distinct boiling points further supports the notion of a chemical change. Boiling point is a physical property that depends on the chemical composition of a substance. Since the two gases have different boiling points, it implies that their chemical compositions differ.
Therefore, the process of electrolysis of water involves a chemical change, as evidenced by the formation of two gases with different boiling points.
