What else can I help you with?
Does a chemical property describe which changes are possible for a substance?
Yes, a chemical property describes the behavior of a substance in reactions or interactions with other substances. It helps predict how a substance will react or change under specific conditions.
Does ripening of papaya under a physical change or chemical change?
yes it is a physical change because physical change means change in which no new substance is formed. so when a mango is ripen there is no new substance formed thus it is a physical change
Can new substances be formed when you observed a chemical property?
Yes, and here is the reason: The Definition of a chemical property is a property in which a substance has a potential to change Identity under certain circumstances in that manner of chemical change. If this substance changes identity, then new substances are produced from the matter that was changed.
What are three signs that a chemical change has occured?
chemical change doesn't apper outside easily as it is change in the chemical property of the element or the experiment done,specific methods can only be used to detect the chemical change for the substance under observation.
Is reduction a physical change?
Reduction is primarily a chemical change, not a physical one. It involves the gain of electrons by a substance, often resulting in a change in its chemical composition. In contrast, physical changes, such as changes in state or appearance, do not alter the substance's chemical structure. Therefore, while reduction is a crucial process in chemistry, it falls under the category of chemical changes.
Is chlorine gas liquefies at 35 degree celsius under normal pressure a chemical or a physical change?
The liquefaction of chlorine gas at 35 degrees Celsius under normal pressure is a physical change. It involves a change in the state of the substance (from gas to liquid) without altering its chemical composition.
What happens when a pure substance undegoes a chemical change?
When a pure substance undergoes a chemical change, its molecular structure is altered, resulting in the formation of one or more new substances with different chemical properties. This process is typically accompanied by observable signs such as color change, gas production, or temperature change. Unlike physical changes, where the substance retains its original identity, chemical changes are often irreversible under normal conditions. Examples include combustion, rusting, and fermentation.
Is dissolving in water a chemical or physical property?
Dissolving in water is a physical property because it does not change the chemical composition of the substance. The molecules of the substance are simply surrounded by water molecules and dispersed throughout the solution without undergoing a chemical reaction.
Is boiling point a chemical property?
Yes, boiling point is a chemical property. It is the temperature at which a substance changes from a liquid to a gas phase under standard atmospheric pressure, and is characteristic of that substance, making it a chemical property.
Is chlorine gas liquefies at - 35 degree celsius under normal pressure a chemical or a physical change?
The liquefaction of chlorine gas at -35 degrees Celsius under normal pressure is a physical change. This is because the change in state from a gas to a liquid does not alter the chemical composition of the substance, only its physical state.
When a substance under goes a physical change its?
The classical example is water with 3 phases: solid, liquid, gas. The transition is called change of phase
What is a substance when it under goes a physical change?
The classical example is water with 3 phases: solid, liquid, gas. The transition is called change of phase.
